Bow Street Duchess Mystery
The Lady's Last Mistake
For years, Lady Cassandra Sinclair has harbored a scandalous secret and a painful loss. Unwilling to trust a man again, and determined to remain single, Cassie throws herself into a confidential project—a private home for pregnant, unwed women. Hope House is now her sole purpose. But after she is seen there by the arrogant lord she once fought feelings for, the walls around Cassie’s secret life begin to crumble. Physician and fourth son of a marquess, Lord Grant Thornton is contented with his reputation as a debauched widower. No respectable lady wants to marry a rogue, and after the tragic death of his first wife, Grant has no intention of marrying again. But his father’s impatience for a male grandchild to carry on the family title spirals into a demand that Grant either remarry and aid in the effort—or be cut off. When Grant discovers Cassie operating the much-whispered-about Hope House in the poverty-stricken stews of Whitechapel, he’s as impressed at her daring as he is furious. He also sees a wicked opportunity…Cassie is appalled when Grant threatens to expose her secret unless she agrees to a staged courtship. With any hope, the child his brother is expecting will be a boy, and Grant will be off the hook. But until then, Cassie intends to make him regret his scheming. Acting the part of besotted couple in public, the two bitter adversaries clash in private, until an inconvenient attraction becomes unruly—and unstoppable.The Lady’s Last Mistake is a standalone companion novel to the Bow Street Duchess Mystery series, where Cassie Sinclair and Grant Thornton first meet. The Lady’s Last Mistake can be enjoyed on its own, however reading the series first is highly recommended. The Bow Street Duchess Mystery series is now complete and available on Kindle Unlimited for binge reading!

Two broken people mending their pieces, together
Rounding to four stars because I love the series, but I had trouble connecting to this one and really feeling the romance.
This was the first romance and final book in the Bowstreet Duchess Mystery series; the long awaited story of Cassie and Thornton (who I didn’t realize was not his given name, more on that). Maybe it was too long awaited for me because, though the story was well written and had good pacing, I felt very disconnected from the couple and did not really feel any passion between them. Maybe I like this author better for a mystery?
Cassie and Thornton had both been through a lot and rightfully were wary of giving in to love or attraction. Each kept the other at arms length and used prickly behaviour to avoid attachment. But then, when they were both forced to work together, they found hidden depth in each other. A worthy story and a heartwarming one. I wish I could have felt more but this lacked emotion and tension for me. I think I needed more time with them together, liking each other before they jumped into bed because they disliked each other up to a half minute before they did. I dunno.
One other point, the historical elements were extremely loose and I had trouble not letting them bother me. Cassie, the unmarried daughter and sister to a Duke lived alone with only a maid and servants at 23 yrs old - so unlikely- especially since her brother kept trying to make a match for her. The author used this set up to make the plot work but I never like convenient disregard for historical realities just for story.
Also I honestly thought Thornton’s first name was Thornton in previous books because he’s referred to as Lord Thornton, and is the fourth son of a Marquess therefore would not have any courtesy title. But his first name is, in fact, Grant. This bothered me to no end because HE SHOULD HAVE BEEN REFERRED TO AS LORD GRANT! Anyone who’s read my reviews knows that I am a stickler for getting titles right in historical romance. I don’t need perfect accuracy but the basics need to be covered.
So in actuality I’d give this book a low three star but because I like the series, the writing and loved seeing glimpses of Hugh and Audrey, I’m rounding up.
Thanks to Booksirens and the author for an early copy of this book.

The story of Cassie and Grant was hinted at in previous books and is told in Book 8 of the Bow Street Mystery. I was surprised as I thought the series ended with book 7 but I understand that there was more to tell about this couple. This could be read as a stand-alone but it is such a good series that I recommend reading all of the previous books. The story starts off strong with each of the leads running charities that are kept secret. There is a mystery regarding one of the young women that lives at Hope House and I enjoyed that. There is a wall that Cassie has built due to being hurt before and Grant has lost his wife and also is resistant to love again. I thought this went on a bit too long and the mystery drifted a bit. This book has one steamy scene, and I loved the ending. 4.5* I received an advance review copy for free, and I am leaving this review voluntarily.

Super Quick Opinion: This was a lovely surprise! I enjoyed it. I enjoyed how it was a slow burn in the best way where they were developing the foundation of their relationship (on page!) and that made it so much sweeter when they finally gave into their feelings and were together. I enjoyed the characters, their banter, and the fact that they both were damaged in their own way but found support in each other enough to be vulnerable and work through their past traumas. I might go back and read others in this series since I did enjoy the author's voice.

What a treat to be back in the world of the Bow Street Duchess series to see Cassie and Grant finally come together! The beloved secondary characters were like magnets flipped on the wrong side. We all knew they'd be great together if they could just get aligned properly. This book explored their past trauma, showed them advancing in their own ways beyond the other series, and let them come together in a beautiful, satisfying (and steamy) way.
Moving this book forward two years since the end of the Bow Street series let us see Cassie and Grant in a new way. She's established in her own household and started a home for unwed, pregnant women who need a safe place to live. Grant's free clinic was part of the other series, but his reliance on family money to keep it going wasn't as clear. Both are being pressured by their families to marry.
When a sick resident of Cassie's home requires care and Grant responds, the characters who have been mostly separated are put back together.
The use of some familiar tropes was interesting. We have two people with secret identities entering a fake betrothal scheme with a side of blackmail. Of course, this has them in constant contact and the relationship blooms. There are a few steamy scenes, including one open-door bedroom scene.
Everyone loves it when characters from past books make a cameo. The entire cast from the earlier books is here and we actually get more than a glace at them. There are several scenes with Audrey, Hugh, Sir, Michael, Genie, etc. I read with a smile on my face!

Explosive!
We all intuited that when Lady Cassandra Sinclair and Lord Grant Thornton, a doctor and the Marquess of Lindstrom’s fourth son, finally came together it would be explosive. It was! Super charged, and so much more.
Cassie’s brother Michael, the Duke of Fournier, won’t give up his matchmaking efforts on Cassie’s part. Cassie wishes him to perdition in the nicest possible way. He has control of her fortune. She wants the money to fund her charity efforts, but definitely no marriage!
Cassie has a secret. Well a couple really. She helps to run a secret retreat for women suffering domestic violence, unmarried mothers, often pregnant servants, abused married women of the ton. It’s call Hope House. That information is well and truly hidden from her family.
Grant’s father has control of his fortune and wants him to marry and get an heir. The only problem is that Grant was married to a woman whom he truly loved. He doesn’t want to marry either.
And yes, Grant too has a secret. Unknown to all he operates a clinic in Whitehall under a pseudonym. He’d be cut off if his father ever got wind of it.
Grant learns of Cassie’s secret and due to his father’s machinations gives her three says to consider a proposal of marriage to him (the engagement later be ended by her). Cassie is furious, but eventually accepts.
A classic enemies to lovers story with volcanic sparks and danger laced throughout.
I just loved these two!

This author was new to me. I enjoyed characters and time/place setting in London. Cassie and Grant’s story was okay. Both had some major disappointments in life and found solace in their work with those less fortunate. Agree with other reviewers that Grant is an a@@, emotionally immature despite his role as Dr and prior marriage. Cassie is sad and I did not feel character growth for her either. Maybe their HEA in an unwritten epilogue would tie up loose ends. But I don’t care anymore, these spoiled brat martyr types are not my favorite.

This is a companion novel to Devlin’s excellent Bow Street Duchess series (now completed). It is classic Devlin and I enjoyed it immensely.
It is the story of Cassie and Thornton who have been at odds throughout the series. I don’t think it’s a spoiler to say they get their HEA but oh, the roller coaster ride to get there is delightful and frustrating all at the same time! So many twists and turns, family drama and secrets being revealed. All that plus a mystery to be solved.
I was thrilled to see quite a bit of Hugh, Audrey and Sir in the book. Seeing a bit of Catherine as a toddler plus a Basil cameo (in his nightshirt no less) was a delightful bonus.
The theme of women’s rights was a strong one throughout the book. In fact it’s been a theme throughout the series. Devlin didn’t hit us over the head with it in my opinion but it was noticeable in a good way. There are also references to inclusion, which is no surprise given Phillip’s proclivities mentioned in earlier books. I enjoyed the subtle nod to ‘Pride’ by the brothel owner’s rainbow party and gown.
I found this book a bit more steamy than the rest of the series which was a good thing I thought. The intimate scenes are well written, enjoyable and rather detailed. Devlin does an excellent job at creating that sexual tension and then showing how it is resolved.
You don’t need to read the series to make sense of this book but they are such terrific books, you’d be missing out if you didn’t.
The book is an easy read and thoroughly engaging. I devoured it in one sitting!
I am looking forward to Devlin’s new series coming in 2025.

September 26, 2024DNF. I always love characters who care for others and do what they can to help. So, I enjoyed time spent with Cassie and Grant. Up to a point. After cruising through the first half of the book, I really got frustrated with Cassie. Yes, she’s only 23 but seriously she apparently has no imagination. Every setback is a complete surprise, and every piece of advice is ignored without thought. It’s one thing to be determined and brave, and it’s something else to be foolhardy. She is completely caught up in her own drama with little apparent ability to understand others. Oh! I didn’t think of that! But she never takes the time to think or evaluate. But when she starts getting happy about her ability to drive Grant up a wall, that was it for me. I don’t find that behavior to be attractive in the least. I completely lost interest in her.

I think I went in expecting to be absolutely in love with this story because of the build up of the dislike between these two from book to book, but honestly Cassie drove me bonkers. Unfortunately that colored this story a bit for me and I feel like this was a bit of a miss in the entire series that I absolutely loved.
The hate to love trope is one of my faves and while that was done well I just didn’t click with these two as much as I had hoped I would.
Devlin writes wonderful stories and this was plotted and written well which is why I bumped it from a mid 3 to a 4.

Cara Devlin is a fairly new author for me. I just finished this whole series and it was so intriguing and so damn good. I was surprised how much depth she got in each book. The funny thing is all the books I read have sex in them and I researched her and thought she had sex in her books and she didn't in books 1 thru 4. Book 5 finally had some but like a sentence or two and not descriptive at all. The other times were mentioned but that's it. But like I said, these have been such greats read it really didn't matter. This is the last in this series.
I really liked this book a lot. I loved Grant and Cassandra. It was funny almost all of the other books had no sex or very little and even though this one has a bit more it was way more than the others. Kind of strange. Anyway, great couple, great story. Just loved it. Overall great read.

For years, Lady Cassandra Sinclair has harboured a scandalous secret and a painful loss. Unwilling to trust a man again, and determined to remain single, Cassie throws herself into running a private home for pregnant, unwed women. Hope House is now her sole purpose. Physician and fourth son of a marquis, Lord Grant Thornton is content with his reputation. No respectable lady wants to marry a rogue, and after the tragic death of his first wife, Grant has no intention of marrying again.
Grant & Cassie have locked horns several times over the years as his best friend Hugh has now married her sister in law Audrey. Their story had to be told as the series wouldn’t have been complete without it & what a lovely story it was. I’d grown to love both Grant & Cassie throughout the previous books & there was always an attraction between them, their banter is wicked & the air crackles when they are together. I loved their journey to a HEA which wasn’t easy but it was so very entertaining. The pace was very good, the characters had depth, there was some angst, some intrigue but most of all two broken people finding each other & becoming whole again – did I shed a tear ? Yes I did at Grant’s proposal & at the lovely epilogue
I voluntarily read and reviewed a special copy of this book; all thoughts and opinions are my own

I'm so sad to be finished with this series. I had the best time with it! I think there's a novella about Hugh and Sir that I still have to read, but after that I'll need to find a new series to binge :(
Even though this book takes place in the same world as the previous books and contains all the same characters, it felt completely different. I loved seeing Audrey, Hugh, and Sir again! And of course adorable Catherine! Their appearances felt very natural and they didn't overshadow Cassie and Grant's story.
I'd classify the other books as mysteries with a strong romantic element, but this book was definitely a romance with a bit of a mystery element. There was a mystery of sorts and some heavy content (I had to stop reading for a bit because it really upset me), there weren't clues or anything for the reader to figure out.
Not that I minded that! I really liked the romance story! It was really cute and Cassie and Grant suit each other really well. I also find it hilarious just how horny Cassie and Grant were for each other. Somehow the author wrote an entire 7 book series and managed to only have mild levels of horniness, but I swear every other chapter Grant or Cassie were lusting after each other. And I didn't ask to learn their kinks, but that's something I know now. Though, when I think about it, it does seem quite fitting for their characters and sets this book apart from the rest of the series. Also, unlike the other books in this series, the sex actually happens on screen (multiple times lol). I don't read a lot of smut so I can't comment on the quality per se, but I appreciated how much focus was on consent and the female perspective. There was still plenty of non-sexual moments between the two of them though, so my romantic heart was satisfied.
I think the author did such an amazing job with the characters. Both Cassie and Grant have gone through some really traumatic experiences, and I'm glad the author explored the complex feelings they had instead of keeping things completely light and fluffy. The book did an especially good job at making the reader emphasize with Cassie. I really felt her pain and the shame that she carried. I just wanted to cry for her and what she had to go through.
I will 100% be re-reading this in the future. If I were to read this outside the context of the series, it's nowhere near the best historical romance I've read, but with all the characterization the previous books gave to Cassie and Grant, I completely loved this.

When we were first introduced to Lord Grant Thornton and his friendship with Hugh Marsden in the Bow Street Duchess series, I either smiled, laughed or would nod my head in agreement to whatever was being said between the two. I thoroughly enjoyed their friendship and was so glad to continue to see him make an appearance as the series went on.
And when Cassie started showing signs of interest towards him and how it quickly turned to them arguing whenever they were in the same room, I had hoped they would get their own story. AND THEY DID!
I have been waiting for their story for a couple months and it did not disappoint. We gain more insight into Cassie and the trauma she has endured from a previous book. We also see why Grant is the way he is because IYKYK.
I laughed more than once because of their banter. I cried a few times because of these two broken souls trying to protect themselves. My eyes felt like they couldn't read fast enough because the different pieces of the story literally left me on the edge of my bed, couch, and seat.
I'm sad this is officially the end of these characters. But it was such a satisfying end for everyone involved.

Thanks to Book Whisperer for the EARC of this book, the concluding book in the series. We have watched Cassie and Grant interact throughout the series, and I am happy they finally have a happy ending, though it took a lot of twists and turns to get there.
Cassie is secretly funding a home for pregnant women, and Grant is secretly funding a medical clinic in the slums, both using assumed names. When they discover this, it is quite a shock to both.
I love when Hugh and Audrey arrive, with their 2 year old daughter and Sir in tow.
Though there is a small mystery, the story is actually about 2 wounded souls who find each other. I was quietly sobbing at the end.
If you have not read the series, I behoove you to start with book #1.

Thanks to BookSirens for a copy of this ebook and this is my freely given opinion...
Cara Devlin... I love you and I hate you.
I love you for giving us a bit more of Audrey and Hugh, and a peek into their hard won happily ever after, especially since I did not want their story to end.
I love you for giving us Cassie and Grant's story, after giving us hints of them and their stories in the previous books, and it was satisfying... I am replete, like after having that rich, and sumptuous dessert after a wonderful, satisfying meal at a favourite restaurant.
But I also hate you, because this feels like an ending - I am sad that there will be no more of these rich, wonderfully drawn characters and their engrossing stories, and it feels like I am in mourning.
I just look to the sign I have on one of my bookshelves, that I made for myself - I get too attached to fictional characters... and have remember it is too too too true. Time to let go and move on to the next book...
This is Cassie and Grant's story and it continues a few years after the last Bow Street Duchess story. Hugh and Audrey are living their life and happiness, and Cassie has gained some independence from her overbearing brother, Michael, the Duke of Fournier. He is still determined to protect her and have her live a conventional life and hopefully marry an acceptable beau. But Cassie remains emotionally traumatized by her past, and determined to provide help for women who may not have the support and resources she had at the time of her secret distress. To this end, she has formed a secret identity and uses her resources to form connections and form Hope House, a refuge for women needing a place to escape abusive relationships, and perhaps give birth, a safe place to heal, and a chance at a safer, secure future for themselves. If they choose, Cassie and her cohorts can either help them find new homes for their babes, or help them if they choose to keep the babes.
But this must be a close kept secret, to keep the women safe, but also any hint of Cassie's involvement with such a scandalous endeavour, would ruin her and taint her family terribly, in the eyes of Society, and she could lose her funds and the support of her brother.
Grant Thornton is the fourth son of the powerful and strict Marquess of Lindstrom . Generally he is ignored or reviled for daring to lower himself to work as a doctor, and living as a rake otherwise, as he drowns his heartbreak from the death of his beloved wife and stillborn child in meaningless liaisons and encounters. But Grant is dependent on his allowance from the Marquess to fund his lifestyle and his secret work running a free clinic for the poor. But the Marquess lays things on the line for Grant, demanding that he marry and provide a much needed male heir for the line, or be cut off by the new year.
In Society, Grant and Cara despise each other, only knowing their Society faces and reputations. But both their secret worlds collide one day when of the women under the care of Hope House needs the care of a doctor, and they call for the services of Dr. Brown, the alias of Lord Grant Thornton.
This is an enemies to lovers, fake relationship/betrothal story as Grant uses the secret of Cara to force her into a pretend courtship to stall his father's threats. But in the course of their forced courtship, they learn to see each other beyond their facades and presumptions about each other, and the banked attraction that started years before that they had been fighting flares, bright and hot.
Combine this with conflicting family relationships and drama, the risk of their secrets coming to light, past trauma on both their parts and the fear of further risks to both their hearts, and danger hanging over Cassie and Hope House. What this all adds up to is a richly drawn out dramatic historical romance with complex characters in an emotionally engrossing story.
Cara Devlin, I love you... but I also hate you a little bit as well.
But I am satisfied and replete. But that does not mean that I am not greedy for more!
(after all... Sir needs a happily ever after too...)

Cara Devlin... I love you and I hate you.
I love you for giving us a bit more of Audrey and Hugh, and a peek into their hard won happily ever after, especially since I did not want their story to end.
I love you for giving us Cassie and Grant's story, after giving us hints of them and their stories in the previous books, and it was satisfying... I am replete, like after having that rich, and sumptuous dessert after a wonderful, satisfying meal at a favourite restaurant.
But I also hate you, because this feels like an ending - I am sad that there will be no more of these rich, wonderfully drawn characters and their engrossing stories, and it feels like I am in mourning.
I just look to the sign I have on one of my bookshelves, that I made for myself - I get too attached to fictional characters... and have remember it is too too too true. Time to let go and move on to the next book...
This is Cassie and Grant's story and it continues a few years after the last Bow Street Duchess story. Hugh and Audrey are living their life and happiness, and Cassie has gained some independence from her overbearing brother, Michael, the Duke of Fournier. He is still determined to protect her and have her live a conventional life and hopefully marry an acceptable beau. But Cassie remains emotionally traumatized by her past, and determined to provide help for women who may not have the support and resources she had at the time of her secret distress. To this end, she has formed a secret identity and uses her resources to form connections and form Hope House, a refuge for women needing a place to escape abusive relationships, and perhaps give birth, a safe place to heal, and a chance at a safer, secure future for themselves. If they choose, Cassie and her cohorts can either help them find new homes for their babes, or help them if they choose to keep the babes.
But this must be a close kept secret, to keep the women safe, but also any hint of Cassie's involvement with such a scandalous endeavour, would ruin her and taint her family terribly, in the eyes of Society, and she could lose her funds and the support of her brother.

Lady Cassandra Sinclair, sister of the Duke of Fournier, is using her pin money from him to operate Hope House, a safe-house for pregnant women, unmarried or unable to keep the child. Grant Thornton, fourth son of the Marquess of Lindstrom, is a physician to the ton who runs a clinic for the poor in Whitechapel. Both face social ruin should their secret—and secret identity—become known.
When the marquess tells Grant that he will stop funding him if he doesn’t become betrothed by the first of the year, Grant uses his knowledge of Cassie’s enterprise to coerce her into a pretend engagement.
Neither counted on falling in love.
It’s an expertly developed enemies to lovers story with an underlying theme of the need for honesty in relationships—even when that honesty requires courage and may result in ostracism.
This is a standalone with characters from the Duchess of Bow Street series reprising their roles, but with Grant, Hugh Mardsen’s best friend, and Cassie, Audrey’s former sister-in-law, as main characters and Audrey and Hugh making essentially cameo appearances. That said, while readers of the mystery series will appreciate the nuances of the reactions of Cassie and Grant to each other in the beginning of the novel, the story is self-contained.
As one expects from Cara Devlin, the characters are fully formed, believable and true to the era in which they are presented. I will admit that The Lady’s Last Mistake is spicier than I anticipated, but the deviations from societal norms are acknowledged by the character as well as indicating the sanction for the violation.

We met Grant and Cassie, two characters who suffered trauma, in previous books of the excellent Bow Street Duchess Mysteries. Grant, Hugh's friend, lost his wife and baby. Cassie, Audrey's sister in law from her marriage with the Duke, suffererd from the lies of a terrible man and had a pregnancy out of wedlock, We saw Grant and Cassie interacting throughout the series and we knew there was chemistry, even if it obviously was a love/hate relationship, both of them with wounds of the heart too deep to build anything.
In this book, we are meeting them doing secret work quite unusual for the ton: Grant, a physician, runs a free clinic in the bad part of town, Cassie runs a house for unwed mothers who need help. Their world collides, and sparks fly. Both running their clinic and house in secrecy, they come to an arrangement to fend marriage pressures from both of their family: they will fake courting... What comes next is pure delight for the readers.
Two characters who are strong and stubborn: how will they let their walls down and see that together, they can be the best team? The progression is realistic and touching because those two aren't perfect and they both admit it. Also, seeing a strong female character who recovers from trauma and finds love with someone who shares her sense of justice was compelling. Grant was hard to like at first but we learn soon enough that he hides a good heart behind those walls he built around him.
There was less mystery than in the rest of the Bow Street Duchess series but there is an intrigue that kept me on the edge of my seat. The romance is beautiful without being kitch: it has depth and layers, and develops into something solid and safe. Personally, I like that this story has a strong vibe of social justice and basic human rights. Those are topics that still resonate today. One of my favorite romance novel in 2024.

I am not the target demographic.
So I have no idea how to rate The Lady’s Last Mistake, as it isn’t a genre I tend to read. I only picked it up because it was related to the Bow Street mysteries, and I liked Grant and Cassie in that series.
Not going to do a proper review, because I’m unfamiliar with the genre, but will point out some issues I have. And apologies in advance if this comes across as preachy. But Grant is not likeable this time out. He threatens Cassie with ruin, and damaging Hope House’s ability to help women in need. He behaviour is as despicable as Renfry, and it shouldn’t matter if he never meant to follow through with the threat. Cassie doesn’t know that.
It is actually an issue I have with a lot of urban/period fantasy with a strong romance plot. Negative behaviour being forgiven because the main character says “I love you”. I find it distasteful and it leaves an unpleasant feeling. What kind of signals are we inadvertently sending to impressionable younger men, and women, with this messaging?
Anyway, preachy rant over. I think I would have enjoyed The Lady’s Last Mistake if Cassie had agreed to the arrangement without the blackmail. Potentially something like, Grant and Cassie agree to the fake betrothal to get their respective overbearing family member off their backs. An old trope I know, but it works. 😁
Not going to recommend one way or the other, as I don’t know enough about regency novels to have an opinion. But I can recommend the main series Bow Street Duchess Mysteries. Thanks for taking the the time to read my ‘review’ rant.

Delicious. This is a companion novel to the Bow Street Duchess Mystery Series, which I can't recommend highly enough. Cassandra and Lord Thornton finally get their HEA. He's a doctor and close friend of Hugh Marsden. He was devastated by his wife's death and felt he could never love another woman. That didn't stop him from becoming a libertine. Cassie was seduced and abandoned at the beginning of this series by a different rogue. She went to Sweden to deliver a child and has kept the secret ever since. Determined not to ever marry, she starts a home for pregnant, unwed women.
Under pressure from his father to marry and produce an heir, he forces Cassie into a sham engagement, hoping that his brother's wife will give birth to a boy. He threatens to expose her secret unless she agrees to the fake engagement. She is simultaneously resentful of, and attracted to, Grant.
An intriguing plot, two flawed and broken characters to root for, and a satisfying HEA. I loved this series, and I'm sad to see it end.

I loved this story! I thoroughly enjoyed the Bow Street Duchess series so I knew I'd like this one. I pre-ordered the book but jumped at the chance to get an advanced copy and read it sooner. You don't need to read the series before this but I think it adds context and more of the back story than the author gives during this book.
Grant and Cassie, the two main characters were prominent in the series so the story of how and why they came together made complete sense. Then a good amount of love-hate, angst, sleuthing and a splash of danger make for a fun read. Other characters from the Bow Street make cameos but don't figure prominently. Part of me wanted a bit more of Hugh and Audrey, especially Audrey but I think I'm pretty happy with the focus on Grant and Cassie. I also love that the author wrapped up the whole story in one book. I can't wait to see more from this author.

I’ve been impatient for Cassie and Grant’s own story throughout Bow Street Duchess 1-7 books. But for readers unacquainted with the main characters, Cassie and Grant are charismatic enough to pique anyone’s interest for their developing relationship.
My favorite thing about Cara Devlin is her smooth, fast paced writing. Like a good movie, each scene does not drag, and always advances the plot.
Unlike previous series, there is no murder to be solved. So without divided attention on collecting clues, I fully immerse myself in the romance blooming, the little moments that builds to love. And the attraction, trepidation, jealousy, desire and want…is all there, just everything I enjoy in a good romance.
The main leads both had sorrowful pasts and hurts that cut deep. I read about the effort they try to be more compassionate, they try to rebuild their lives around new purpose, try be strong to love again. This is the part that moved me the most.
So The Lady’s Last Mistake is what I expect and what I need for the finishing touch in Bow Street Duchess series. Love it.

The Lady’s Last Mistake is book 8 in Cara Devlin’s A Bow Street Duchess Mystery series.
Unlike the other books in the series, the main character in this book is not the duchess, but her former sister-in-law, Lady Cassandra (Cassie) Sinclair. We have met her in previous books where she had some interactions with the hero of this story, Lord Grant Thornton.
I was so excited to read this book because the previous encounters between Cassie and Grant left me wanting to see more of them, and hoping they would get a story that put them together. Their attraction to each other in the previous books was undeniable, and I’m happy to say that their story did not disappoint.
Cassie and Grant’s story was such a touching one, there were moments that brought tears to my eyes. I was so happy to see the two of them share a happy ending. This is one book in the series that should not be missed.

Loved it!!
I was surprised by how much I actually enjoyed this book. Not because of the author(LOVED the rest of the series). But because Cassie is not, and has not been, my favorite character. I like her better after this book but I’m still not a fan. I absolutely hated the way she treated Grant (and in general acted like a total brat) before now but she’s grown, and grown on me! I loved the story even minus the usual mystery and investigation. And I’m really sad that this is the end. Wonder if we could get a series of a grown up Sir now?!?!

Oh Wow!! It was as good as I hoped for. I just love the characters in this series and knew I was going to love this final love story. It did not disappoint with the development of the relationship, the way they uncover one another’s secrets, the disapproving family and friends, and the fierceness of commitment. I have been hooked since book one because having strong protagonist women who defy the rules of society to follow their hearts speaks to me. The character development is wonderful and feels in line with real life. You get to know them, cheer and mourn with them. The author has her finger on the pulse of what readers want. Can’t wait for more.

Cara Devlin does longing like no one else. Thornton and Cassie have both been favourites of mine (and everyone else) through The Bow Street Duchess series, so I was really excited about this book and it didn't disappoint. There's no paranormal element here and the mystery, if it can be called that, is just the background for the development of Cassie and Grant's relationship, but it was not a problem for me. The book is not without flaws, and the hot and cold messages from both MCs got a bit old towards the end, but as a whole it was not only a good companion novel but a great story in its own, and that epilogue was perfect. I'm definitely reading whatever Cara Devlin writes next.

Beautiful story
Cara has skilfully woven words together to form a romance with humour, tension, twists, danger, compelling characters, and healing. It moved me to tears. Thank you for your commitment to write and send your stories out into the world for us to enjoy.

4.5 stars but rounded it down because it really does not meet my new requirements for 5 stars.
Will come back for a full review later. Some historical anachronism that can pull the reader out of the story.

This is a great page-turner, could not put it down. The characters are strong and the plot compelling. Recommended for fans of the genre.
