The Lady's Guide to Death and Deception

Rate this book
What is a spy willing to do when both her heart and her country are at risk?

Life changes once again for British spy Miss Mary Bennet when Napoleon Bonaparte escapes from the Isle of Elba. Mary quickly departs England for Brussels, the city where the Allied forces prepare for war against the French. But shortly after her arrival, one of the Duke of Wellington’s best officers is murdered, an event which threatens to break the delicate alliance between the Allies.

Investigating the murder forces Mary into precarious levels of espionage, role-playing, and deception with her new partner, Mr. Withrow—the nephew and heir of her prominent sponsor, and the spy with whom she’s often at odds. Together, they court danger and discovery as they play dual roles gathering intelligence for the British. But soon Mary realizes that her growing feelings towards Mr. Withrow put her heart in as much danger as her life. And then there’s another murder.

Mary will need to unmask the murderer before more people are killed, but can she do so and remain hidden in the background?

This is a wonderful Jane Austen cozy series. Although it's the third book, I easily read it as a standalone. Jane Austen's characters are reimagined in a clever way. Mary Bennett is a spy, helping Mr. Witherow gather intelligence after Napoleon escapes. Meanwhile, Lydia is married to Mr. Wickham and hiding a terrible secret. Can Mary help her? And how is Mary coping with her growing feelings for Mr. Witherow?

This is a compelling combination of thriller, romance, and family drama. Mary is a fantastic protagonist who can go undercover as a man one moment and fight off a wicked husband the next The attraction between Mary and Mr. Witherow is very well done and progresses naturally. Mary and Lydia's relationship as sisters is explored as well. The story is captivating, satisfying, and enjoyable, and Mary shines in her role of spy.. Fans of Jane Austen will delight in this new adventure with beloved characters.

I received a free copy of this book from the publisher via Netgalley. My review is voluntary and my opinions are my own.

I adore Katherine Cowley’s version of Mary Bennet and this book has her coming into her own after a few years of training with her spy group. Her team is in Europe as Napoleon makes his way to the Netherlands with Waterloo serving as the epic culmination of the story. Along the way, we get beautiful developments in Mary’s romantic life and we get to see Lydia and Wickham.

This book could be the end, but please don’t let it be! I don’t want to let these characters go!

3.5 stars rounded down. A cozy mystery set in the context of espionage and war, The Lady's Guide to Death and Deception is a spin-off of the Pride and Prejudice character Mary Bennet. I jumped into this book, the third in the series, without having read the first two, and so it did take me a little bit of time to find my footing with a few characters. That said, this held its weight as a standalone if you're like me and not necessarily planning to embark on the whole series.

Mary Bennet is a lady, but she's also a spy. And she's been tasked, along with her colleague Mr. Withrow, to solve the murder of a duke's officer. Traveling to Brussels to track down clues, sometimes dressing in disguise as a male to enter into places she cannot go as a woman, and falling in love with her colleague along the way, Mary sheds more and more of her innocence as the case progresses.

I found the writing and historical research solid and interesting, though the pacing was a bit slow to start. I'm curious to hear about Mary's start as a spy, though perhaps not enough to pick up book one. I did love the unique premise of a female spy in the early 1800s, as that's not an era you typically think of females as having much of an active role in. Thank you to NetGalley and Dreamscape Media for providing a copy of this book for honest review.

I wasn’t sure exactly what to expect when I picked up The Lady’s Guide to Death and Deception by Katherine Cowley. This is, after all, my first book by the author, and it’s usually not a good idea to jump into a series on the 3rd book. However, that’s exactly what I did in this case – and my reading experience did not suffer in the least. While I do have the first two books, I haven’t yet had time to read them, but it did not affect my enjoyment or understanding of this book at all. I found the plot to be easily followed, delightful to read, and engaging in every way. In fact, the romance only really comes into play in this third book so, although I’m definitely going back to read the whole trilogy in order, I’m also kinda glad I started with the romantic book. Because…. #kissingbooks

Mary Bennet is often the most overlooked character in Jane Austen’s Pride & Prejudice. She’s awkward and bookish and overly prim. However, in the hands of Katherine Cowley’s creative imaginings, Mary blossoms into an endearing character with a heart of gold and a courageous spirit. Because – wait for it – Mary Bennet is now a spy for the Crown. Isn’t that just perfect?!? I thoroughly enjoyed watching how the author incorporated Mary’s quirks – which some might perceive as flaws – into assets and even into qualities that capture her partner Mr. Withrow’s heart. Readers get the sense that he has fallen in love with her because of these eccentricities (and what they show of her heart), not in spite of them. He also definitely brings out a new, bolder, side of her, as her feelings for him increase. I love this summary of Mary’s feelings toward one of their kisses:

“It was as if someone had managed to capture a year of happiness, put it in a jar, and then dispensed it all at once.”

Shortly after this book opens, Napoleon has escaped Elba and retaken France and is mounting an army, bringing the work that Mary, Mr. Withrow, Lady Trafford (and others) are doing all the more important. Brussels provides the stage for their drama to unfold – and there is definitely drama! Murders of high-ranking officials and rumors of war nip at their heels, causing Mary & Henry (Mr. Withrow) to employ whatever means necessary to root out critical information … and a killer. I especially loved the scenes where they go undercover as detectives Fothergill and Pike (both male – it was super fun to watch Mary deal with a mustache and male mannerisms), and I would love more books to that effect. Amid the intrigue swirling around them, Mary is also reacquainted with her sister Lydia – which brings about an entirely different kind of drama, one that will engage a wide range of emotions for readers.

Bottom Line: Oh, Mary Bennet – who knew you could be such a delight? I absolutely adored the way this author brought Austen’s underrated character to life on the pages of The Lady’s Guide to Death and Deception – with dignity, quirkiness, lots of heart, and incredibly plausible what-ifs. Before reading this novel I would never have said I could see Mary Bennet as a spy for the Crown; now, I can’t imagine her having any other future in the years after Pride & Prejudice. Warmth, wit, and a dash of swoony romance (those kisses!!) merge fabulously with the high-stakes intrigue in which she and Mr. Withrow (a lovely mix of Darcy & Knightley, with layers all his own) must engage. Fans of Jane Austen, Regency romance, and historical mysteries should not miss this book!

This is the best book yet! The Lady’s guide to Death and Deception does not disappoint. The book kicks off first thing, (Chapter 1 is amazing, WOW Mary! You go girl!) As always the story is balanced with a interesting mystery that draws you in, life lessons with Mary, Awesomeness and in this book… romance.

I’ve said it before, I love how Katherine Cowley writes amazing novels without just relying on romance and hand holding. She stays true to Mary Bennet but helps us understand her. Mary Bennet is amazing!

In this book we visit Brussels, where the preparations for fighting the escaped Napoleon are happening. Everything is in a whirl, and we hit the ground running. Costumes and secret roles. Mary even disguises herself as a man. Historically speaking, we know women have joined many an army in secret, but I haven’t read a story where a lady spy donned the role of a male investigator. It’s also makes for some adorable scenes with our love interest, It’s kinda hard to build a romantic relationship when you’re both dressed as men.

I also love meeting historic figures, Wellington! Wellington!! <3 I love the balance of History and awesome story! (Waterloo teeth, anyone?)

The mystery is perfect, I didn’t even guess anywhere close who done it! Interesting, well thought out and just a delight! I wish I could talk more about the mystery, but I won’t give it away. Just know you will enjoy it.

And the romance, sigh… perfect. As I said, from dance classes to parading as a man, It’s all adorable and I love it all. I also loved the healthy relationship that develops. I get so frustrated at novels with romance and the relationship is actually toxic, except all the times the author tells us that, it’s totally fine that he ignores and pushes past her morals and convictions, (I’m sorry, forcing kisses on someone, isn’t romantic, it’s creepy.) and the girl flip flops between every decision and is a strong powerful woman who doesn’t need a man, but somehow isn’t complete without a boyfriend. It’s a big pet peeve of mine, so I soooo adore The Lady’s Guide to Death and Deception! It’s cute, it’s fun, they learn, they grow, they. Are. PERFECT. Sigh.

We get to see Lydia Wickham and help her out a bit. We see a little bit of Kitty, who is now a spy in training (Woohooo!). We see old friends and make some new. We use old spy techniques and get to learn some new stuff. Treat yourself with this book, and geek out with me, it’s quite a ride.

It has been an honor to review this series, I’m proud to have been a part of its journey. If Katherine Cowley ever asks me to review future stories, I would not hesitate. As always, I was provided an ARC in exchange for my honest review.

I didn't like this one and it took me ages to listen to it. It went all over the place. I figured out the whodunit pretty quickly and did NOT enjoy the outcome. The plot veered off into domestic violence which is not at all what Jane Austen intended for her characters. Then it got into the history and politics and then the romance, back to the Battle of Waterloo before remembering this was supposed to be a mystery. The body count was very high for a Jane Austen themed mystery. That doesn't even include Waterloo! Waterloo is bloody and gory but not as detailed as An Infamous Army but similar conclusion after the battle.

I liked Mary's disguises. That was a lot of fun but she's still not a great spy. Her character growth is very good. The story started off rather scandalously for Mary and for Jane Austen. Mary needs to learn how to kiss to be an effective spy and suggests practice, which Lady Trafford readily agrees to. This sets up the romance. I also love nerdy neurodiverse Mary. She can't read social cues, even now and doesn't know when a gentleman is sending signals he would like to speak of marriage to a young lady. She SHOULD have realized what was happening with her sister and who the murderer was.

Mary has grown so much. She's an empathetic and caring big sister, recognizing the past faults of herself and her older sisters. Well, their father set them an example with his disinterest didn't he? Poor Lydia had no one to guide her and support her. Everyone rolled their eyes at silly little Lydia and ignored the fact that their parents weren't parenting and thus Lydia winds up with the dastardly Mr. Wickham! He's even more dastardly here which doesn't ring true to me. Mr. Wickham is a charming opportunist but not clever and very lazy. He relies on his charm to get what he wants. Jane tells us it's Lydia who keeps asking for money and Lizzie sends her some on occasion.

One quibble reviewers have with the story and I too thought the same at first - is that Mary says Uncle Gardiner made Wickham marry Lydia. Of course WE know this isn't true but when Lydia lets it slip Mr. Darcy was at her wedding, only Lizzie heard that and pursued the facts. ONLY Darcy and Lizzie and Mr. Gardiner know the whole story. I don't think Mrs. Gardiner knows the whole story herself but enough to tell Elizabeth. Mary doesn't so of course she would give the reader the wrong information. The story is from Mary's point-of-view. There's a lot Mary doesn't know.

I missed Mary's friend Fanny. Miss Tragore shows up late in the story and I had forgotten who she was for a moment. She doesn't have a lot to do. It's all Mary and Mr. Withrow in this one. Mary makes a new friend, a widow grieving her husband who was killed fighting the French. She's in Brussels to enjoy the peace celebrations and enjoys making Mary blush with scandalous gossip. She's a flibbertigibbet and not a real friend. If she were a real friend she would stop gossiping and scandalizing Mary and have a real and meaningful conversation. You can say they've only just met but they're on a first name basis already.

This story was too dark for me and too meandering.

I really like this narrator. Her voice is pleasing but sounds older than 20-something Mary.

Mary Bennet Continues to Save the Day!

Rating: 4.5 out of 5 stars

Source: Review Copy from Blog Tour


TYPE OF NOVEL: Pride and Prejudice Sequel about aa Secondary Characters

SERIES: The Secret Life of Mary Bennet #3 (Even though this book is a standalone, I’d recommend reading Book One and Book Two of this series prior to this book).

THE PREMISE: Mary Bennet’s adventures as a spy take her to Brussels, where Wellington is preparing the Allied troops and the world is waiting for Napoleon’s next move. But in between investigating murders and donning multiple disguises, Mary Bennet discovers that her feelings towards her investigating partner, the insufferably critical and cynical Mr. Withrow, have grown inexplicably more complicated…

MY THOUGHTS: Here we go! The climactic culmination of Mary Bennet’s adventures as a spy. She has evolved and grown so much in this series, and now Mary is thrust into dangerous territory, surrounded by death and war. For those of you who have yet to start this series, here is a little recap. After Mr. Bennet’s passing, Mary Bennet is invited to visit distant relations who train her to be a spy. And through her new companions and their spy work Mary loses some of her judgmental, pedantic, and cringe-y ways and opens herself up for deeper relationships.

As with the other two books in this series, I continue to love witnessing the gradual and gratifying evolution of Mary Bennet. In this installment of the series, we see some new boldness in her as she bravely speaks her mind and pushes to ask hard questions. She is often in discord with Mr. Withrow, and I loved seeing how she wasn’t intimidated by him and frequently called him out on his moods and behaviors. In addition, I also loved seeing how Mary handled her encounters with Lydia and George Wickham. Her relationship with Lydia has always been one of disconnection and distance, and yet Mary valiantly protects and cares for her sister. I thought Lydia’s circumstances and her relationship with Mary were thoughtful and creditable developments that provided a very satisfying subplot.

However, what I loved most about The Lady’s Guide to Death and Deception was Mary’s relationship with Mr. Withrow. There is an exciting undercurrent of admiration and attraction between these two that emerges in this story and simmers for its duration. Yes!!! Finally I have been waiting for this! I love the idea of Mary Bennet falling in love with someone she originally disliked and believes dislikes her. I thoroughly enjoyed all the scenes these two shared together and I loved seeing them pair up together a lot in this installment. I especially enjoyed seeing Mary turn her scientific and analytical mind towards Mr. Withrow and how she would assess her body’s own reactions to him.

And with our dear Mary journeying outside England and encountering famous figures like the Duke of Wellington and the Prince of Orange this third book of the series had a bit more amplified excitement and action. As always I appreciate how Katherine Cowley painstakingly tied her story closely to actual events of history. It was thrilling to be taken right into the center of the action and see the events leading up to and during the Battle of Waterloo. And in general I found the murder mystery fascinating – and one that I solved incorrectly. In addition, I loved all the characters and disguises Mary and Mr. Withrow embodied to go undercover. Their additional subterfuge added some new excitement and diversion for this adventure.

Like Mary Bennet, this series is accomplished, intellectual and full of surprising hidden depths. And Katherine Cowley’s newest installment – The Lady’s Guide to Death and Deception – is where Mary’s exquisite transformation reaches its apex. The Secret Life of Mary Bennet series is a terrific choice for readers who believe Mary Bennet possesses main character energy and would make an exceptional female Sherlock Holmes! I think this might be the conclusion of the series, but part of me is hoping for a spin-off with Kitty as our lead…

TITLE: Lady’s Guide to Death and Deception
AUTHOR: Katherine Cowley
PUB DATE: 09.06.2022 Now Available

As a Jane Austen fan, there is nothing more thrilling to me than see a favorite character, Mary Bennett reimagined as a spy gathering intelligence, during the time when Napoleon escapes. The writing was suspenseful and really hard to put down. Lady’s Guide to Death and Deception is the third book in this trilogy, and the stories just keep getting better and better.

I love how Cowley incorporates a well plotted mystery, sprinkle in a well deserved romance for Mary, and seeing sisters Lydia and Kitty make an appearance here. The series is quite the read that I highly recommend - it was intriguing, fast paced, and a thrilling historical fiction at its finest. Well don’t Kathy Cowley for on incredible series.

A Lady's Guide to Death and Deception by Katherine Cowley is the third installment in The Secret Life of Miss Mary Bennet series and I must say it just keeps getting better and better. I am completely hooked to this series, and I truly hope we will have more works to read in the future.

In this story Miss Mary Bennet travels with Mr. Withrow and Lady Trafford to Brussels where she will be at the center of the Napoleonic wars. I loved all the new secondary characters that appeared on this story and the fact that apart from the spying game, we are also privy to personal griefs and different ways of coping with them, domestic incidents and the usual feelings that come along with them and even some war scenes that will leave scars hard to forget. But above all, I love how this author continues to present Mary’s character to the reader.

Mary Bennet has been growing on many different levels throughout this series, but in this book the author gave her even more dept by forcing her to deal with feelings she had never felt before. Mary will feel what love is for the very first time, she will make new friendships and learn how to trust and confide in people, she will realize how much the love for a sibling can be conflicting, and she will have to deal with the feeling of loss, regret and guilt at the same time. I believe this is a feeling that will change and scar Mary forever, and I absolutely loved to see that the author made her a three-dimensional character, someone who has her own thoughts, concerns, beliefs, desires, traumas. backstory and ultimately someone who feels real.

When it comes to her spying, Mary is at the best of her game in this novel! I was amazed with how much Mary’s character has evolved, how much she has learned, and especially how she improved her skills, she has learned new talents and perfectioned old ones, and I believe she will no longer need the assistance of more experienced spies.

From the fist book in the series, I’ve mentioned that the lack of romance was a positive aspect but that a romantic relationship seemed to be building and I would love for it to be developed in the third novel. It appears the author answered my prayers, as Mary is finally entitled to her own love story. I loved how true to character this romance was. It was unique and completely in line with Mary’s character and experiences. I loved the fact that this would not have been a love story easily applicable to any other young lady. It was simply Mary’s story! The unique and interesting love story was also due to the romantic hero in this book who has also demonstrated a fascinating development, and whom I’ve come to love. If there is a fourth book, I want to know more about him!

Just like in previous books, Mary’s sisters play a part in the story, and I liked the fact that a different sister is explored by the author in A Lady's Guide to Death and Deception. Not only it was interesting to see a new sibling dynamic, but also to see how Lydia’s life has been since her father’s death in the first volume of the series. Her character was also very remarkable and well developed. In fact, the author’s ability to develop characters is impressive and probably my favorite characteristic in her books.

A Lady's Guide to Death and Deception is a smooth and balanced continuation of a wonderful series which I hope to continue reading. This book is incredibly well written, well thought of, engaging, and fast paced.  There was so much I loved in it, and how the story is presented to the reader, that I truly hope to see another book in the bookstores soon.

1815. In this Pride and Prejudice sequel Lady Trafford, Henry Withrow and Mary Bennet travel to Brussels to help gather information in their role as spies. But soon an officer is murdered and Withrow and Mary investigate. How many must die before the murderer is revealed.
An enjoyable well-written historical mystery, another good addition to this series with its very likeable main characters.
Another entertaining re-read of this story.

Katherine Cowley is a new-to-me author. I am grateful that I have the opportunity to participate in this blog tour because she is now on my radar and I look forward to reading more of her work.

Mary Bennet is a naive spy. She has closely held morals, which I happen to admire, that are not always the best ways to gather information. There is a scene where she learns that kissing is an acceptable way to learn things. She doesn't believe it, but she puts it to the test. She picks the spy that a kiss would leave the least impact and kisses him. It backfires. Now she knows what desire feels like. Seriously, I don't think I could get the grin off of my face for a while. Later in the story, she has the opportunity to try it again with someone else and learns that not all kisses are created equal. Having the right partner makes a big difference. She also learns that jealousy is not a fun thing to live through.


The mystery that she and Mr. Withrow are trying to uncover is who killed one of Wellington's officers. The investigation puts the morals of Mary to the test when she puts on a pair of trousers and plays the part of a gentleman. Katherine Cowley definitely has a sense of humor.

The Lady's Guide to Death and Deception takes the reader on an adventure of romance, mystery, and the art of spying. I'm glad that I gave this book a try. It was well worth my time and invigorated my imagination.

It was fun to read about Mary as a full-fledged spy during the events of the Napoleonic Wars. She has grown so much! A satisfying conclusion to the series. This book does feel a bit heavier than the previous books in the series as it addresses some tough topics. TW: abuse, war

Title: A Lady’s Guide to Death and Deception (The Secret Life of Mary Bennet #3)
Author: Katherine Cowley
Narrated by: Alison Larkin

Length: 10 hours and 36 Minutes

Who is your favorite underdog in literature? Mary Bennet is definitely not the favored sister in Pride and Prejudice, but I am glad to finally see her get her own story. The Secret Life of Mary Bennet series has done an excellent job giving Mary a well-rounded personality and story of her own.

Book three of this series, has an excellent title, A Lady’s Guide to Death and Deception. Mary has accompanied Lady Trafford and her heir Mr. Withrow to Brussels. Napoleon has escaped the island of Elba. The Duke of Wellington and his forces are in Brussels readying for their last battle with Napoleon. When one of the Duke of Wellington’s officers is murdered, Mary and Mr. Withrow are on the case to discover the identify of the murderer. Will they catch the murderer before he strikes again? Will Mary and Mr. Withrow realize their feelings for each other?

I greatly enjoyed this novel. Mary continues to develop as a character and spy and I’ll admit, I really got a kick out of her dressing up as a man and investigating the murder with Mr. Withrow. I also loved the balls and how Mary seemed to have captured the eye of the Prince of Orange. My favorite part of this novel was the inclusion of Lydia and Mr. Wickham. It was a very strong story. Mary realizes that her family abandoned Lydia due to the scandal, but never bothered to check on her, happy to have her away from them. She has become a victim of domestic abuse with no one to turn to. This storyline causes Mary to grow up in a way more deeply than anything else. As she experiences the Battle of Waterloo, she comes to realize what is most important in life.

I enjoyed the historical note at the end of the novel. It was a great conclusion to the trilogy, but I’ll admit to wanting more. I want to see what new adventures Mary has yet in store.

I was delighted to discover that Alison Larkin was the narrator of this audiobook. She is one of my favorite audiobook narrators. I love her English accent, smooth voice, and narration style. She was an excellent narrator of this audiobook.

A really satisfying conclusion to a series that I've enjoyed listening to on audiobook very much! I've become fond of Mary while reading these books and this was an excellent ending to her adventures in the Napoleonic wars, moving the setting to Brussels and adding in a murder mystery plot around the lead-up to the Battle of Waterloo. I liked that the previous two installments didn't have any romance in them and were mostly focused on Mary's character growth, but the romance that developed in this one was lovely–I greatly enjoy romance between characters who are in cahoots together and have great respect for the other one, and solving a murder gave Mary and Mr. Withrow much more page time together so we finally get more of his thoughts on her and a greater look into his mind. Things wrapped up in a satisfying manner (and Mr. Wickham got what he deserved) but if the author ever wrote further adventures with Mary and co, I would happily read them. Also, I would like to shout-out the audiobook narrator for this series: I only started listening to audiobooks regularly in the last few months, but I really enjoyed her narration, thought that she did solid voices for all the main cast, and greatly appreciated that unlike the terrible new Napoleon movie I (regrettably) went to see during the course of listening to this audiobook, all the characters actually have the correct accents, including the French ones.

Absolutely fantastic read from a solid series by Katherine Cowley. The development and growth to Mary’s character is so well done, that even though this book can be enjoyed as a standalone—you will truly reap the benefits by starting at the beginning and reading both 1 & 2.

I’m a total sucker for authors that dig deep into true historical events and include them in their books. The Battle of Waterloo has been of interest to me since my teen years, so you can imagine my delight that Cowley used this event in this book.

Mary has become quite the star of the Bennet family (at least to me) through this series, and her interactions with her family have taken on a new meaning.

The romance felt natural and doesn’t dominate. There’s a perfect balance of romance and mystery. Cowley delivers a well-rounded novel with something for everyone.

I think this might be my favorite of the three, and I really loved every minute.

So I read this one as a standalone and commemorate this author, she took characters from a well-loved Pride and Prejudice and made them her own. That on its own was absolutely amazing! Then, her mystery and development of the characters are outstanding. I really enjoyed this book a lot!
Mary is a spy working with Mr. Withrow and while they have worked together in the past this time is entirely different. Mary at first was in denial about her feelings toward Mr. Withrow, but soon she realized that she held a deep regard for him. However, while investigating murders and helping the Duke of Wellington her emotions and feelings have to be put on the back burner.
I do have to say that this novel was the perfect mixture of romance, mystery, and dramatic events to keep the reader engaged along with on the edge of their seat! The mystery had me on my toes until I was blindsided by the actual murderer and the reasoning behind the murders! Sooo good! I am definitely looking into the first novels in this series because I am hooked!
I received the audiobook from Dreamscape Media and Netgalley and this definitely was a treat! The narrator was stunning and had the best pace and voice for the story! I definitely recommend this book and the audiobook! It doesn't matter which one you pick up you will not be disappointed!

4. 5 stars Really enjoyed it. There was a lot of focus on the run up to the Battle of Waterloo and its aftermath. Some of that was a little hard to read. The half a star mark down was for the presence of Lydia and Wickham. I can always do without them.

I received a gifted copy from Austenprose and Tule Publishing.

I’ve only just discovered this series, so I confess I’ve not read the first two books yet, but I felt like this worked well as a stand alone novel. The author cleverly develops aspects of Mary's personality that we're all so familiar with from Pride and Prejudice to make Mary an adept spy. Merging spy work with her high moral standards creates internal conflict for the ever serious Mary, as does her attraction to Mr. Withrow, a fellow spy. Part of her work is spent incognito as a man, allowing her to play both spy and detective. A few other Bennets make an appearance too. There's humor, adventure, intrigue, romance and Waterloo. This was such a fun read!

What a delightful and unexpectedly strong entry in this series!

After a relatively poor second volume, I was hesitant to read this third installment but am so glad I did as everything that plagued the second book (awkward integration of historical elements, poor character development, and lackluster pacing) is gone here. The history and historical characters are well rendered and beautifully integrated into Mary's ongoing story, Mary herself is better drawn and more interesting, and the plot moves along nicely, providing a few moments of real tension and suspense. Cowley seems altogether more confident in her voice and there are some exceptionally lovely bits of prose and some somber themes that are sensitively handled. I also loved the romance here-I've been anticipating it since the first book and was not disappointed. It was sweet, heartwarming, and touchingly awkward at times-all the things one would expect given this particular couple.

Other reviewers seem to feel this is the conclusion to this series and I will be satisfied if it is, but given how confident and strong this recent volume is I would be pleased to follow Mary's adventures further.

Napoleon has escaped his island prison, and England’s best spies have been sent to Brussels to gather intelligence as the continent sits on the brink of battle. Mary Bennet, in company with Lady Trafford and Mr. Withrow, are called upon to investigate the death of one of the Duke of Wellington’s officers. As the threat of Napoleon’s offensive advances ever closer, they must determine whether gambling debts, old rivalries, or French intrigue is at play in the murder. Along the way, they must overcome their prickly sensibility to each other’s company and perhaps discover that there could be more to their relationship than an uneasy truce.

This story of Mary Bennet’s growth in spycraft is the third in a series. In preparation for this blog tour, I read the opening installment. There, plain spinster Mary Bennet was invited to stay with Lady Trafford (a distant relation?) to learn more accomplishments as she prepares to become a governess…or is it really to become something else? I struggled to suspend disbelief in this initial book. (Why on earth would Mary’s family, including Elizabeth, let her stay with strangers without inquiring who they were? Why would anyone ever want Mary Bennet to be a spy with her total inability to read people or understand nuance?) In the opening novel, Mary’s character was as obtuse and ungraceful as might be expected, but I did not like the character as Jane Austen’s Mary Bennet and I did not understand the reasoning behind her selection or metamorphosis.

However, I discovered upon reading the third installment of this series, that I really did like the character as Katherine Cowley’s Mary Bennet. With some distance now from her “origin story,” the highly literal Mary is a unique character in Regency spy fiction, and even semi-believable as a burgeoning femme fatale. Whenever she needs to assume a new role, she thinks: what would Jane (or Elizabeth, or Kitty, or Lydia) do? And then goes and does likewise… Lady Trafford’s nephew, Mr. Withrow, who is a cold and standoffish character in the first book, comes alive in the third book. As spy heroes ought to be, he is a keen strategist, a sturdy pugilist, and an excellent kisser. All in all, this book was an enjoyable exploration of a unique woman who has now deviated far enough from Jane Austen’s Mary Bennet to be the heroine of her own tale.

The Lady’s Guide to Death and Deception is the third installment in the series, The Secret Life of Mary Bennet, by Katherine Cowley. It is a Pride and Prejudice-related book that imagines sister Mary Bennet as a British spy.

After the death of their father, Mary and Kitty are pulled into the spy life. Now Mary and her colleague, Henry Withrow, are sent to Brussels to assist Wellington in the volatile times when Napoleon escapes from Elba.

Initially, Mary and Henry are just information gatherers, but a series of murders draws them into greater danger as the world moves toward the Battle of Waterloo.

I enjoyed seeing Mary change and grow, discovering love with her companion. At the beginning of the book, we still see Mary’s moral strictness and naivety. She was challenged on many levels—using a pistol, disguising herself as a man, learning to waltz, and more.

In Henry, she found someone who appreciated her logical mind and innate kindness. Mary discovered new dimensions of herself, and Henry gained the confidence to connect with her.

The Lady’s Guide to Death and Deception is an engaging mystery with a budding romance and an interesting look at historical events. The events leading up to the Battle of Waterloo and the battle itself are described with many details. Placing the main character in this setting allows the reader to see events through her perspective. It is an ambitious topic for the author to tackle, but she does an admirable job. ~ Diane, NovelsAlive.com

I was intrigued by the blurb for the Lady’s Guide to Death and Deception by Katharine Cowley- the idea of the prim and pious Mary Bennett from Pride and Prejudice as an undercover spy during the Napoleonic wars seemed far-fetched. But I have to say the author has pulled this off and keeps Mary true to her character.

I hadn’t read the previous books in the series prior to this one, but this made no difference to my enjoyment of the book. The author cleverly gets us up to speed with the characters, their pasts and as in any Austen-like book, their deeply repressed desires.
The Mary Bennett in this book is quietly feisty, loyal, brave and as expected respectable which can only get in the way of being a woman spy. The way Mary has to navigate the social niceties while being a woman and a spy was funny.
I guessed who the murderer was fairly quickly but that didn’t stop me from enjoying Mary and Mr Withrow trying to solve this. There were a few scenes of war and its aftermath that made it hard reading but war in any period is not pretty.
I don’t normally enjoy romance but the growing romance between Mr Withrow and Mary was lovely despite the two lovers unconsciously trying to sabotage this.

I look forward to reading the author’s backlist

3.5 stars rounded down. A cozy mystery set in the context of espionage and war, The Lady's Guide to Death and Deception is a spin-off of the Pride and Prejudice character Mary Bennet. I jumped into this book, the third in the series, without having read the first two, and so it did take me a little bit of time to find my footing with a few characters. That said, this held its weight as a standalone if you're like me and not necessarily planning to embark on the whole series.

Mary Bennet is a lady, but she's also a spy. And she's been tasked, along with her colleague Mr. Withrow, to solve the murder of a duke's officer. Traveling to Brussels to track down clues, sometimes dressing in disguise as a male to enter into places she cannot go as a woman, and falling in love with her colleague along the way, Mary sheds more and more of her innocence as the case progresses.

I found the writing and historical research solid and interesting, though the pacing was a bit slow to start. I'm curious to hear about Mary's start as a spy, though perhaps not enough to pick up book one. I did love the unique premise of a female spy in the early 1800s, as that's not an era you typically think of females as having much of an active role in. Thank you to NetGalley and Dreamscape Media for providing a copy of this book for honest review.

I am a sucker for anything Jane Austen. I especially love the variations of her novels in which supporting characters become the stars. Fun spin-offs, if you will. Katherine Cowley has created the perfect role for younger sister Mary Bennet in her Secret Life of Mary Bennet series. Mary a spy? How unexpected and thoroughly charming! I listened to the audiobook of The Lady’s Guide to Death And Deception, book 3 in the series, and was immediately swept up in the intrigue and mystery. The combination of old favorites (and not so favorites) from Pride And Prejudice and historical figures of the day made this book unputdownable. While staying true to Austen’s depiction of Mary, Cowley has certainly created a very grown-up version of Mary. I loved her prim and proper manners as she dons disguises, practices her shooting, and finds romance. This book is a must-read for Janeites! Even though it was book 3 of the series, I had no trouble following the plot or adjusting to this new side of Mary. I do, however, HAVE to read books 1 and 2 now! Thanks to Cowley for adding more to my TBR stack. 😉 I very much enjoyed the audiobook. The narrator was spot-on. The Lady’s Guide to Death And Deception is a highly recommended read or listen!

Highly Recommended.

Audience: Adults.

I truly love Katherine Cowley's depiction of the overlooked Bennet sister. Mary is quiet and sometimes off putting in Pride and Prejudice, but is that all there is to know about her?

This story is a fantastic continuation of the previous two. The story itself can stand on it's own, but the evolution of Mary is best seen over the course of the three books. I know that I had never really appreciated Mary, until now.

The depiction of a shy, loyal girl trying to figure things out is something that I think we can all relate to. She is trying to navigate society's rules while breaking them as an agent for the crown. I would have never placed her in this role and yet I can't see the story turning out any other way. We also get to see Lydia and how that all turned out and Kitty joins Mary. It is a fitting story that gives us more of the Bennet family than just Lizzy and Jane.

I would recommend this story and series to fans of Pride and Prejudice. It stays true to Jane Austen and brings a new and compelling adventure that wouldn't be in this world without a little romance as well.

I received and early copy through the publisher and this is my honest review.

The teaser: Life changes once again for British spy Miss Mary Bennet when Napoleon Bonaparte escapes from the Isle of Elba. Mary quickly departs England for Brussels, the city where the Allied forces prepare for war against the French. But shortly after her arrival, one of the Duke of Wellington’s best officers is murdered, an event which threatens to break the delicate alliance between the Allies.

This was a delightfully entertaining mystery with intrigue and romance thrown in. The main character - Mary Bennet is described as a straight laced person such as found in Jane Austen’s characters. Through the unravelling of the mystery of the deaths her character and that of her accomplice Mr Withrow are developed.

I found I had to remind myself of the period for which this story is written as the style seemed to be too formal. However the twists and turns held my attention until the end, and what a revelation that was.

I received an advance copy of this book and leave my review voluntarily.

England 1815

This is my favorite book of the series so far. Mary has grown a lot since she first caught Lady Trafford’s attention, and it really shows in this story as Mary takes on situations, challenges, and moral dilemmas which she simply could not have handled before. She tackles several new spycraft skills including disguises, establishing unknowing informants, the French waltz, and (possibly) seduction.

Note: This is the third book in the series. I tried to just jump into this one, but I felt like I was missing too much backstory and character development, especially in the case of Mary and her past dealings with Mr. Withrow. I’m really glad I did this. Mary grows so much as both a person and a spy in the first two books, which made her actions in this one much more believable to me.

Side Note: I really like the way that this series explores Mary’s relationships with her sisters. I’m sort of hoping Kitty gets a spin-off book or two.
