Marius Quin Mystery #5
Arsenic and Old Lies
A dead body in the study, a terrible wrong to put right, and a trail that leads to murder…
London, 1928. Mystery writer and amateur detective Marius Quin is reeling from his friend’s murder in his own home. Forced to stay away from the case, he’s in urgent need of distraction when fate points him towards Felicity Mortimer, a woman imprisoned for poisoning her husband fifteen years earlier.
Marius soon becomes convinced of Felicity’s innocence, and when he discovers a key witness with his throat cut, it’s clear that the real killer is still on the loose. Determined to uncover the truth, Marius drags his partner-in-crime-solving, Lady Bella Montague, (not to forget his basset hound, Percy) to a manor house deep within the New Forest. But what dark secrets are concealed at the picturesque estate where Felicity once lived?
As their search for answers stirs up more violence, can Marius and Bella expose a deadly plot before death stalks the halls of Rhinefield House… again?
A captivating and atmospheric 1920s mystery that will delight fans of Agatha Christie, T E Kinsey, and Lee Strauss.

About the author
Benedict Brown
52 books500 followersWriting has always been my passion. It was my favourite hour a week at primary school, and I started on my first, truly abysmal book as a teenager. So it wasn’t a difficult decision to study literature at university which led to an MA in Creative Writing. I spent a long time writing kids’ books, including funny fairy tales, dystopic adventures and serious issue-based YA, before switching to murder mysteries last year.
I grew up in a crime fiction family and spent a long time dreaming up the idea for my detective Izzy Palmer’s debut novel. A Corpse Called Bob is my first full-length book for adults in what is already becoming a long series.
I’m a Welsh-Irish-Englishman originally from South London but now living with my French/Spanish wife and slightly muddled daughter in Burgos, a beautiful city in the north of Spain. I write overlooking the Castilian countryside, trying not to be distracted by the vultures and red kites that fly past my window each day.

Marius Quin is an author of mysteries and he likes to investigate them as well. Together with Lady Bella Montague they make an excellent team.
The story begins in London in 1928 when Marius discovers a dead man in his home. The body belongs to one of his friends who is also Bella's fiancé. He is too close to the crime to be able to investigate it so instead he takes up the cause of Felicity Martin, a lady who has spent fifteen years so far in prison for the murder of her husband. Marius and Bella work to prove her innocence.
This is an excellent mystery with good characters. I enjoy the author's writing style very much. Four stars. Thanks to Netgalley and the publisher for the opportunity to read and review this book.

ARC for review. To be published July 11, 2025.
3.5 stars
This is book 5 in the Marius Quin series, an enjoyable cozy mystery set (and I am not a cozy mystery person at all but I really like the ones written by this author, especially his Lord Edgington books. Brown does so much great research and he tells you all about it at the end. That is fun for a nerd like me.). But I digress. Oh, and the book also gives you a reminder of what happened in book 4, in case you forgot (which, naturally, I had.)
Gilbert Baines, Lady Bella’s finance is found dead in Marius’s writing room and a calling card from Lucien Pike is found alongside the body (Pike figured prominently in the previous installment in the series.). Who would want to do away with Gilbert (well, besides Marius, since he’s still in love with Bella, but I suppose it wasn’t him….but wouldn’t THAT be a shocker!)
Anyway, the police won’t allow Marius to have anything to do with Gilbert’s case so, to keep himself busy, he starts investigating the cold case of Felicity Mortimer. Felicity has been in Holloway Prison for fifteen years, convicted of murdering her husband on what Marius is convinced is little evidence. He convinces Bella it will help her grief to assist him and off they go.
I liked this fine, I guess. I’m still going to need Brown to go back to using Percy’s full name, but I was glad to see so much of him here. I much prefer stories with Marius’s fun mother, aunt and uncle - they are adorable and funny. But this was OK. And great quote: “I adore libraries, perhaps even more than bookshops. The very smell as you enter should be sold as a perfume, though it’s a good thing it’s not, as, like an overly excited schoolboy, I would fall in love with every woman who wore it.”

I love the entire series. This book leaves the reader with a cliff hanger, once again. The characters are delightful. I was surprised by whom the murderer was. Such a fun, engaging story. Highly recommend.
I was blessed with an ARC. The opinions expressed are my own and unbiased. I’m eagerly anticipating the next book in the series.

The fifth book in this very good series, as with all series I have to read them in order as I love how characters & relationships develop & change, so whilst this book could be read on its own I appreciated it more by having read the earlier books. Another well written well paced book with strong characters & an intriguing story. I really like Marius & enjoyed the mystery he sets out to solve to take his mind off the body in his writing room. There are twists, turns & red herrings & I was kept guessing as to who the villain was. I also love how the author takes you back to the inter war years. Another very good addition to the series

Marius Quin writes mystery novels and is also a private investigator alongside his friend and one time sweetheart, Lady Bella Montague, and his basset hound, Percy. Having found a dead body he isn't permitted to investigate, he did find it in his own writing room, he looks for something else to fill his time. The case of Felicity Mortimer fires his interest and, convinced of her innocence, he begins to look closely at the evidence even though she has been incarcerated for fifteen years having been convicted of killing her husband. Determined to right what he sees as a terrible injustice he, Bella, and Percy head for the New Forest to see what new evidence can be unearthed. Not everyone is pleased to see them however, and as they begin to uncover secrets long hidden they may have unwittingly put themselves in a killer’s sights?
I was able to read an advanced copy of this thanks to NetGalley and the publishers, Storm Publishing, but the opinions expressed are my own. The fifth book in the Marius Quin Mysteries was my first but it was a fun read, with twists, turns, interesting locations and an underlying mystery which is yet to be solved. The author's notes at the end were fascinating and added an extra level to the reading experience.

This exciting adventure story follows the misadventure of mystery writer and wannabe detective Marius Quin. Now I haven't read the other books so I'll leep this brief. A dead body is found in his house and of course Marius is a suspect even though he didn't do it and a clue that he didn't do it is that the supposed murderer left a calling card with the name Pike on it. Marius also finds himself drawn to another case that happened years before as well.
I received an arc copy from Netgalley and all opinions are of my own.

The end of the fourth book in this series (A Body at the Grand Hotel) and the beginning of this book gives us a murder that is pretty monumental in the series- spoiler alert - the death of Bella's fiancé Gilbert Baines, found murdered at Marius' desk in his flat.
Yet, this murder is completely set aside and Bella and Marius instead become involved in the poisoning and death of Richard Mortimer 15 years prior, for which his young wife Felicity was sentenced to death, later communed to life in prison. Marius senses a miscarriage of justice and he and Bella manage to get invited to the family estate, where they investigate past and present crimes.
Granted, the case is a very interesting one with plenty of twists and turns and a very satisfying ending. And most intriguing is that it all is based on the true case of Florence Maybrick, circa 1890's England.
Where this doesn't work for me was the "misdirect" from Gilbert's death to the other case and the way in which Bella's grief and dealing with the death seems unfocused. Marius adores Bella but so far, within the series, he seems to not understand her at all, and we as readers are left with the same situation. As the series progresses, I hope that Bella's character becomes more fully developed and that she gets some closure from Gilbert's death. 3.5 stars.

I. Am. Obsessed.
Reading this, I felt like I was transported back to childhood, watching Poirot and Miss Marple with my mom in the summer. I realize that's a very specific feeling that many won't relate to, but if you enjoy a "cozy" mystery, this is your book!
Marius? I love him. Bella? She's great, I want more from her. Percy? Let's be real, he's the star of the show.
The case itself became predictable relatively quickly once all the suspects were introduced, although I was wrong with the actual do-er of the deed, so that was exciting. I appreciated that all of the clues that Marius had, we had as well. I DESPISE when I'm reading a mystery book and vital information (that the main character will have learned during the investigation) is withheld to keep readers from figuring out the mystery.
I haven't read anything from this series (or author), so I really jumped in the deep end with this. Brown does an excellent job of catching up new readers without (at least from what I could tell) overloading folks who have read the previous books and don't want to sit through a million recaps. I look forward to reading the next book that comes out. In the mean time, I need to catch up on the first four books!
Thank you to the publishers and NetGalley for the advanced copy!

Marius and Bella on another case right out of the headlines
I really enjoy reading the Marius Quin series. Marius, like Christopher in the Lord Edgington series, is quite the humble fellow. I’m sure he has no idea how brilliant he truly is. Saddened, perplexed and banned from solving a crime committed at his flat, he finds himself in the public library looking for a new/old case to use as inspiration for his next novel. An intriguing case is left on his desk and Marius is off to solve the mystery. With Lady Bella having multiple social connections, they are admitted to a grand house where a wife was wrongfully accused of murdering her husband. The suspects pile up and the “who-dun-it” begins!

It’s been awhile since I read a murder mystery book, and this book perfectly scratched that itch for a Sherlock Holmes-esque British murder mystery with obscure clues and surprising twists. I liked the writing style well enough most of the time, but every now and then the character seemed to be addressing the audience which I didn’t love since the rest of it seemed to be more of an internal monologue which took me out of the story. But I enjoyed the book overall and definitely need to check out the rest of the series!

July 1928, when the body of Gilbert Baines, fiance of Lady Bella, is discovered in his flat, Quin is warned off investigating. He becomes interested in the fifteen year old trial of Mrs Felicity Mortimer, who was sentenced to life in prison for the murder of her husband. It doesn take long for a death related to the case to occur and vital documents stolen. Soon Lady Bella becomes involved as well.
An entertaining and well-written historical cozy mystery with its likeable main characters. Another good mystery in this enjoyable series.

A few years ago I read one of Benedict Brown’s first stories in his other 1920s series, Lord Edgington Mysteries, I really enjoyed it. So I went into reading this – which is the fifth in Marius Quin’s adventures, and not totally disconnected from the other series – with high expectations.
I wasn’t disappointed.
Despite being the fifth book in a series, the narration immediately pulled me in. The natural-sounding, very personal first-person narration certainly played a major part.
Marius’s voice is close and friendly, and it has the effect of making you feel as if he is telling the story directly to you across a mug of coffee. He is a witty, very English man, and I greatly enjoyed his sense of humour as well as his self-deprecation. I also fell very quickly for his sense of justice and – despite what he always says about himself – his generosity.
Marius is seeking inspiration for a story that he can love – unlike the one he is currently working on, which his publisher loves but he detests. As he often does, he visits the library to browse through old newspapers. A fifteen-year-old case catches his attention, and even from the scant press reports, he immediately starts to think that something very wrong happened there. He decides to meet Felicity Mortimer, the woman convicted for murdering her husband, in the prison she’s kept and comes out surer than ever that she is innocent.
So he and Bella, his ‘partner in crime’, start an investigation to try and help her get out of jail.
I really liked this part of the story because I was never certain until the end whether Marius was placing his trust wisely. Everyone has their opinion about Felicity, some swearing by her innocence, others certain that she was and still is a very skilled manipulator of people.
Marius and Bella find a way to get into Felicity’s family’s country mansion, and I have to say the setting is masterfully created. The place is a relatively new mansion with a very strong fairy-tale character, a dark, almost gothic atmosphere, home to people who perfectly complement the place.
Felicity’s acquired family is eccentric and very interesting, dysfunctional and still very close. You can never be sure who you can trust because it is very clear that everyone has secrets. All of them know each other’s secrets (for the most part), and all of them protect each other’s secrets. It’s a crazy system, and yet once you know what’s going on, you almost understand why it exists and why it works.
I loved the family dynamics because I could always feel there was more to know, and yet discovering anything was extremely difficult.
The mystery is intricate. Only at the end do you fully understand how much.
I almost wanted some of it to be revealed a bit more slowly rather than have all the explanations concentrated at the end of the novel. However, I suspect this was a storytelling decision on the author’s part. And anyway, it didn’t take away anything from the enjoyment of the story.
It was an excellent read around a well-thought-out plot, and I really really enjoyed it.

Review: Arsenic and Old Lies by Benedict Brown
Overview
Benedict Brown’s Arsenic and Old Lies is a delightful plunge into the world of cozy mysteries, blending wit, intrigue, and a dash of dark humor. Set in 1928 London, the story follows amateur sleuth Marius as he untangles a web of deceit surrounding a suspicious death. With its charmingly eccentric characters and a plot that twists like a country lane, this book is a love letter to classic whodunits—Agatha Christie fans, take note.
Key Strengths
-Atmospheric Setting: Brown nails the 1920s vibe, from smoky parlors to razor-sharp dialogue that crackles with period charm.
-Puzzle-Box Plot: The mystery unfolds with precision, dropping just enough breadcrumbs to keep readers guessing (but never frustrated).
-Character Chemistry: Marius is a endearingly flawed protagonist, and the supporting cast—especially the quirky locals—steals every scene.
-Cozy Yet Crisp: The tone balances lightheartedness with genuine stakes, making it both escapist and engaging.
Considerations
-Pacing: Some middle chapters linger on red herrings, though the payoff is worth it.
-Trope Reliance: A few classic cozy mystery clichés pop up (e.g., the nosy vicar), but Brown injects them with fresh energy.
-Emotional Depth: While fun, the story prioritizes cleverness over profound character arcs.
Score Breakdown (0–5 Stars)
-Plot: ⭐⭐⭐⭐ (4/5) – A tightly wound mystery with a satisfying unraveling.
-Characters: ⭐⭐⭐⭐ (4/5) – Vibrant and memorable, if not deeply transformative.
-Setting: ⭐⭐⭐⭐⭐ (5/5) – Transportive and rich in historical flavor.
-Originality: ⭐⭐⭐ (3.5/5) – Familiar beats elevated by sharp execution.
Overall: ⭐⭐⭐⭐ (4/5) – A poisoned teacup of pure, addictive fun.
Who Should Read This?
-Devotees of Murder She Wrote or Miss Marple seeking a new fix.
-Readers who love mysteries with humor and heart (minus the gore).
-Anyone craving a weekend read that’s equal parts clever and cozy.
Final Thoughts
Brown delivers a mystery that’s as comforting as a fireside armchair—until the next twist sends you bolting upright. Arsenic and Old Lies proves that the best lies are the ones we happily fall for.
Gratitude
Thank you to NetGalley and Benedict Brown for the advance review copy. This book was the perfect escape, and I’ll be first in line for the next Marius adventure!

Once I received the ARC for this story, I immediately read the preceding four Marius Quin books so that I was familiar with the characters. I am glad I did; however, you definitely can read this as a standalone.
While not a fan of period mysteries, this series is definitely an exception to that due to the main characters’ charm and Mr. Brown’s descriptive writing. I enjoyed this book and the previous stories because the main character of Marius Quin, a novelist, has combined forces with his childhood friend, Lady Bella Montague, to become detectives. This has been a successful endeavor for them as they have a 100% solve rate so far.
The last time we saw Marius, he had discovered Lady Bella’s fiancé dead in his study. Because he is not able to investigate the murder, he finds another case to work on by going to the library and reading old newspapers. He reads about Felicity Mortimer’s case and is not convinced that she is guilty of murdering her husband and goes to prison to meet her.
Through research, he discovers a man who could help him exonerate her, but he ends up murdered right before Marius can talk to him. If that wasn’t bad enough, the documents he obtained from Felicity’s attorney are stolen from his car. Clearly someone doesn’t want her released.
Marius enlists Bella to help him investigate and they are able to obtain an invitation to the house where the alleged murder took place in and meet Felicity’s deceased husband’s family—two sisters (Deirdre and Ursula), their husbands, and their children. There are a lot of twists and turns in this story because not only are Marius and Bella investigating Felicity’s case, but Deirdre’s husband ends up murdered. I found it puzzling that he was murdered when Ursula was so annoying.
I loved this story as much as the previous four Marius Quin mysteries. You feel like you are part of Marius and Bella’s investigation. I am baffled by the Lucien Pike storyline, though. Why is he just now becoming involved in Marius’s life? I cannot wait for more of this storyline to find out why he is just now popping up and what his endgame is for Marius. Plus, will Marius get a second chance with Bella or has that shipped sailed? I hope for more books in this series!

Title: Arsenic and Old Lies
Series: Marius Quin Mystery Book #5
Author: Benedict Brown
Publisher: Storm Publishing
Genre: Cozy Mystery
Pub Date: July 11, 2025
My Rating: 4. 2 Stars
Pages: 305
Set in 1928 London, this story follows mystery writer Marcus Quin and his one-time sweetheart, Lady Bella Montague, as well as his basset hound, Percy.
Story spicks up after Marcus finds the body of Gilbert Baines slumped over his desk in Marcus’ writing room. Marcus is beyond shocked. Gilbert is someone he knew – in fact, he is Lady Bella’s fiancé and Marcus really didn’t like him but he never wanted him dead.
Since Marcus is too close to this case he is requested aka forced to stay away from the case.
So he is needs of distraction and looks for something else to fill his time. The case of Felicity Mortimer sparks that interest as he was convinced of her innocence. So look closely at the evidence even though she has been fifteen years since she was convicted of killing her husband.by poisoning him.
Aww we find out in that Felicity was inspired by a real character Florence Maybrick.
I have read several Benedict Brown stories and I know the back of the book is full of information – a must read. In fact, a story in its self!
Additionally Mr. Brown has a very detailed section entitled “Historical Research”.
Another fun section entitled ‘Words and Phrases’ with Brit words and or slang
-E.g. Shoeing horn- now referred to as an appetizer
-Get an iggri on – get a move on
Plus many fun others!
There is also a Character List with new as well as Returning Characters
I am looking forward to more Marius and Bella sleuthing adventures, also hoping for a romantic relationship – perhaps Book #6!
Want to thank NetGalley and Storm Publishing for this enjoyable eGalley.

Arsenic and Old Lies is the fifth book in Benedict Brown’s Marius Quin Mysteries, and it delivers everything you want from a Golden Age–style whodunit: an atmospheric country house, eccentric suspects, family secrets, and a determined amateur sleuth who refuses to let justice slip through the cracks.
The story begins with a shock—Marius Quin discovers the murdered body of his friend in his own study, a thread that ties back to earlier books in the series. While the police urge him to step aside, Marius turns instead to a cold case that has haunted him: Felicity Mortimer, a woman imprisoned for the poisoning of her husband fifteen years earlier. Convinced of her innocence, he and his partner-in-investigation, the clever and sharp-tongued Lady Bella, head to the Mortimer family’s country estate to uncover the truth.
What follows is a tangle of long-buried grudges, family intrigue, and more than one shocking death. Every character harbors secrets, and Brown makes clever use of this atmosphere of mistrust to keep readers guessing until the very end. The eccentric Mortimer family could easily step off the page of a Christie or Sayers novel, yet they feel fresh and unsettling in their own right.
Marius’s narration is a highlight of the book—witty, self-deprecating, and tinged with melancholy, especially as he continues to pine (quietly, and with charm) for Bella. Their partnership balances humor, heartbreak, and sharp deduction, giving the mystery both warmth and emotional weight.
The conclusion is both surprising and satisfying, tying together threads of guilt, loyalty, and justice. Benedict Brown also grounds the mystery in historical detail, drawing inspiration from the real-life Florence Maybrick case, which adds depth without overwhelming the story.
Arsenic and Old Lies is intricate, entertaining, and brimming with the kind of twists that keep you reading past midnight. Fans of historical mysteries will find themselves right at home.

Storm Publishing very kindly invited me to read an advance copy of Arsenic and Old Lies, and after reading the synopsis I was only too happy to accept. That was a good decision on my part, because I adored this book. With a title like that, how could I not? (I love the play on that old classic, Arsenic and Old Lace.)
The main characters in the book, and indeed the series, are friends Marius Quin and Lady Bella Montague, who are private detectives. Marius also happens to write murder mysteries. The book opens with Marius returning from a weekend away, to discover a body in his study. The deceased is none other than Gilbert Baines, Bella's fiancé. 🗡
Finding himself shut out of the investigation into Gilbert's death, Marius returns to his writing, and it is while seeking inspiration from old newspapers at the library, he stumbles upon what he deems to be a miscarriage of justice. 🗡
The subsequent investigation undertaken by Marius and Bella makes for interesting reading, not least because the trial Marius read about is based on a real life one. Sadly, the outcome of both differed.
Set in the late 1920's, Arsenic and Old Lies is a fast paced, thrilling read. There's quite the cast of characters, all of them interesting, and all harbouring secrets. There's also a dog, an adorable Basset Hound called Percy, who is Marius's faithful friend. 🐶
There are twists aplenty, and some welcome humour of the dark variety. 🗡
It has become a habit of mine when reading ARCs, to come into a series somewhere in the middle. Arsenic and Old Lies is book 5 in this series. I haven't read the four books which precede it, but I didn't feel like I was missing too much information. I will circle back to read them eventually. 🗡

You had me at the title!
What’s not to love about such a clever play on the title of a Christie novel?
Mystery writer Marius Quin discovers a dead body in his study. Forbidden by the police to investigate he seeks a distraction and latches onto an old case, where he believes a woman has been wrongfully imprisoned for the poisoning of her husband. Marius sets off to investigate, along with sidekick Lady Bella Montague, which leads them to a country house, another murder, locked doors, and tight-lipped relatives.
I started out loving this book – a sort of Lord Peter Whimsy but for the modern reader, with the motor cars, new fangled telephone, and general sense of decorum. The setup – a dead body appearing in the author’s study – was intriguing, and I accepted the tangent of needing something to distract Marius from this distressing situation. The gentle humour (who doesn’t love a detective with a dog, especially one so adorable as Percy) was a deft touch, and the cast of privileged characters were sufficiently irritating as to be engaging.
For me the ‘love’ went to ‘like’ in the final quarter of the book. The action dropped off and there was an awful lot of talking (verging on explaining) which lacked tension and got a little wearing. That said, I didn’t see the murderer coming, and the final solution was a surprise. The overall atmosphere and setting, along with the characters of Marius and Bella carried this one over the line, and I would happily give the author the benefit of the doubt and dip my toe in with another read by Benedict Brown.

Thank you to the publisher and NetGalley for an ARC of this book in exchange for an honest review. All views and thoughts are my own.
I can't believe I was sleeping on this series all this while. At some point, I'd started reading the first book, Murder at Everham Hall and abandoned it. I'm so glad I requested an ARC of this book, however, because it made me realise I'd been missing out!
The series follows Marius Quin, a mystery writer who also solves mysteries in his spare time with his almost-lover Lady Bella, who is trying to overcome the grief of her fiance being killed and his body dumped in Marius's study. Marius is told to keeps his hands off investigating the murder and on a whim, takes up a cold case for solving and tries to help a woman currently in jail, falsely convicted of a murder she didn't commit. Or so she says.....
I did find it a bit odd that this book covers a murder in the first chapter that's just left to be investigated by the police and then pivots completely to a different murder committed a while back as the focal murder. The theme running through this series is that there's a major story arc running throughout the series but somehow the murder that takes up the book isn't part of the main theme. This is an interesting premise and one I haven't come across before. Not entirely sure that I'd say it works but it's also a good reason to continue an entire series, so there's that. The author has done a great job with his research and identifying a similar case which made headlines back in the day. Marius and Bella make a great investigative team and the humour laced throughout the book is a great foil to their natural, easygoing camaraderie (when Marius isn't pining for Bella, haha). The actual murder they investigate is viewed through the lens of the present judging the past and it's an interesting take on what 'modern' principles in the 1920s would have been in terms of the judicial process as well as the perception of women. Lady Bella is a spirited woman who holds her own in their little duo and challenges Marius intellectually often, which is how a team should function. The reveal of the actual murderer is quite shocking and unforeseen (I definitely didn't expect THAT) and there's subtle commentary on nature vs. nurture when it comes to the ability to kill.
I would definitely enjoy reading the rest of this series. Definitely a 4 star read.

A gripping murder mystery solved by Marius Quin and Lady Bella. Some say a good mystery is one where you don't solve it as you read and all is revealed at the end, but I love it when you "work" along with the detectives to come to the same conclusion.....maybe with a few extra details to be revealed at the end.
"Arsenic and Old Lies" by Benedict Brown is the first time I have met Marius and Bella, so I'm don't know their past history, but this is Book 5 of the Marius Quin Mystery series.
Set in 1928, there are two murders in quick succession. Marius, who is a murder mystery author by day and ameatur sleuth on the side, is on a mission to solve these. But he has also been waylaid by hearing of Felicity Mortimer, who is imprisoned, apparently for a murder she did not commit.
We meet the quirky inlaw family members of Felicity, who have gathered at an old manor house. Complex family dynamics and a culture of secrecy won't make it easy for Marius and Bella. And so we are taken through a twisting turning investigation with false starts, humour and heartbreak as we witness another murder.
I love the relationship between Marius and Bella....witty and a comfortable love and respect for one another. Research for this book was obviously intense (summarised at the end) with Felicity's circumstance based on Florence Maybrick, fascinating real sites like St John's Square, The London Library and the New Forest area provide a rich setting for a mystery I very much enjoyed.
Thanks to NetGalley, Storm Publishing and Benedict Brown (no relation I believe) for my copy.

I thank NetGalley and Storm Publishing for an advance reader copy of Arsenic and Old Lies. All opinions and comments are my own.
The saga of Lucian Pike and what he has planned for Marius Quin and Lady Bella continues in Arsenic and Old Lies. And so does the issue of lovelorn Marius, who is pining for his lost love as she grieves for her dead fiancé in this latest in Benedict Brown’s post-WWI historical mystery series. At least they have another convoluted mystery to take their minds off their own troubles, a “cold case” that too many people would like to see left dead and buried. “Arsenic and Old Lies” soon becomes much more than a search for justice for someone wrongfully convicted (Marius begins to realize the case was criminally botched).
The bodies keep popping up. There’s a bit of a twist at the end. Something they have realized, and something that will bring additional justice. At least happiness will be had for a few, after jealousy and pure evil has had its day and been defeated.
The About This Book and the Historical Research sections at the end of the story are full of information -- but be alert for spoilers! The author always includes tidbits that make for interesting reading. Filled with characters that make you care about what they’re doing, and an underlying plotline that is becoming more and more mysterious, Arsenic and Old Lies is well worth sessions of happy reading.

Well this was a busy one!
From a death in the first page to a long ago miscarriage of justice and new murders, we still have our stately home, our bumbling detectives - although they have both grown in confidence - and all the hallmarks of a good 1920's mystery.
By 30% of the way through the book, so much had happened that I couldn't even begin to guess where the other two thirds could possibly go. This was the most action packed of the Marius books. I have read them all, but there is a handy little recap in the first chapter so I don't think you need to have read the previous ones to be able to understand and enjoy this.
It was a little bit of a shame that so little of the book was actually devoted to Gilbert - he was a recurring character, he meant a lot to Bella and I hope that he doesn't become just a footnote like Marius' father, trotted out at the start and end of every book. We need answers to what happened. Also, Marius, its really not a good look to be that enamoured with Bella so quickly after what happened. I know you love her, but you were far too light hearted about the whole thing.
The story was one of the stronger in the series, a good set of murders, a really good, evil motive, and a charming cast of characters. A very pleasant read.

This is book five in the Marius Quin series. The story is set in the charming yet treacherous world of 1920s London. The story kicks off with a shocking murder that hits close to home for Marius Quin, a mystery writer and amateur detective.
The storyline is both thrilling and engaging, drawing you into an intricate web of deceit, danger, and the relentless pursuit of truth.
What I particularly enjoyed was the delightful banter between Marius and his resourceful partner, Lady Bella Montague, along with the charming antics of Percy, the basset hound. Their camaraderie adds warmth to the chilly atmosphere of London.
The author has a knack for creating vivid settings that almost become characters in their own right.
The blend of historical detail and sharp, clever dialogue elevates the narrative beyond a simple whodunit, making it a delightful read for fans of classic mysteries.
Whether you’re familiar with Marius Quin’s previous adventures or diving in for the first time, this book promises to keep you captivated. Grab your favorite blanket, curl up, and prepare for an escapade filled with intrigue and a dash of humor.

When Marius Quin discovers the body of Gilbert Baines, Lady Bella's fiancee, dead in the writing room of his home, he is shocked. A card was left behind with the name Lucien Pike, a notorious criminal who may or may not actually be involved. Fortunately, Detective Inspector Lovebrook showed up which made Marius feel slightly better. The only thing Marius could think to do was to inform Bella in person, much as it would hurt them. Fortunately, Marius' dog, Percy, was with them to help comfort Bella.
To complicate matters somewhat, Chief Inspector Darrington does not want Marius or Bella to be involved in investigating Gilbert's murder. Even Lovebrook feels that Marius would have trouble being impartial if involved in this case. As an alternative, Marius decides to look into the case against Felicity Mortimer, who was accused of murdering her husband.
Who killed Gilbert Baines? Why was he killed? Will Gilbert's murder be solved? Is Felicity really guilty of murder or is she being framed? Can Marius and Bella unravel the mystery and prove whether Felicity is innocent or guilty?
Benedict Brown has another wonderful mystery with the latest Marius Quin Mystery. The situations and characters are very realistic.with plenty of twists and turns to keep the reader involved clear to the end.

Who killed Gilbert Baines? Why was he killed? Will Gilbert's murder be solved? Is Felicity really guilty of murder or is she being framed? Can Marius and Bella unravel the mystery and prove whether Felicity is innocent or guilty?
Benedict Brown has another wonderful mystery with the latest Marius Quin Mystery. The situations and characters are very realistic.with plenty of twists and turns to keep the reader involved clear to the end.

Maricus Quin, mystery writer and amateur detective, visits the London Library with hopes to find inspiration for the plot to his next mystery. What he finds is the story of Felicity Mortimer who was convicted of poisoning her husband 15 years before. Reading more, he becomes convinced she is innocent. With the help of Lady Bella, he visits the Felicity Mortimer's husband's family and discovers spite and mysteries enough to fill several detective stories. But will he be able to clear Felicity and free her from jail or will someone put him to rest forever...
The story starts off with Quin discovering the body of a friend murdered in his house. This is a carry over of a storyline in previous books which I haven't read. Brown was able to concisely bring the reader up to speed without it feeling like an info dump. That isn't actually the main storyline of this book; Quin trying to prove Felicity Mortimer's innocence is. It kept me guessing until the end.
This is a smart mystery with engaging characters and humor. Brown also includes a lot of historical information at the back in his author's notes which aren't necessary to read but are fun and informative. I need to go back to read of this series.

Secrets and murder
I loved this installment of the historical whodunit series staring Marius Quin and Bella Montague. The book had a layered storyline, an intriguing mystery, surprising plot twists, and touch of suspense. I was equally desperate to read it all at once to solve the mystery but also to savor it and make it last. Marius Quin is a private investigator and an author of murder mysteries. When his ex-girlfriend’s fiancé is found dead in his home and he is unable to help the police, he turns to investigating the potential innocence of a woman’s 15 year old poisoning conviction. Despite her grief, Bella agrees to help solve the case and things only get more interesting when more bodies show up. The investigation leads Bella and Marius to unlikely places, dead ends, plot twists, secrets, and surprising revelations. There are smaller personal story arcs and social commentary which enrich the main plot line and give the characters even greater dimension. Despite this being the first book I’ve read in the series, I did not feel as if I was dropped into the middle of a plot and missing some back story. Since I enjoyed this book so much, I am so happy there will be more books to read in this series.

July 1928. The body of Gilbert Baines, fiancé of Lady Bella, is discovered in Quin's flat, so Quin is recused from investigating. To distract himself from his own problems he finds himself investigating the case of a woman judged guilty of poisoning her husband fifteen years ago. There were mixed feelings about that judgement at the time, so Marius contacts her at the prison and begins the investigation. That leads to the next murder. Throughout, Marius is nagged at by his publisher to produce the mystery novel that he promised.
Not an unbiased review because I laughed my sox off reading the other books in this series! Excellent historical cozies with a wicked sense of humor that makes them perfect for ignoring reality. The end notes and historical research are well worth reading, too.

Mystery writer Marius Quin is avoiding the murder in his own home when he’s drawn into the case of Felicity Mortimer. Though she had been imprisoned for poisoning her husband fifteen years earlier, Marius quickly becomes convinced of her innocence. With his sleuthing partner Lady Bella Montague, and their loyal basset hound Percy, his search for the truth leads them to a secluded manor in the New Forest, where buried secrets and a deadly plot threaten to erupt once more.
It was a delight to return to this series. This book hits the ground running. Marius is met with the death of his partner’s fiance in his own home. Naturally, he cannot investigate it himself and needs something to occupy himself. Because the novel his publisher is expecting is not taking shape. Thus, Marius throws himself into an old case.
I liked the pace of this book. It had my attention from start to finish, and I was never sure what was going to happen next. It all flowed naturally. Lady Bella had my sympathy as she worked to solve a murder while grieving the loss of her fiance.
Overall, this was a fantastic follow-up to the previous book. Anyone who is a fan of cozy historical mysteries will definitely enjoy this one.

Another great mystery to add to the series! I really enjoy following Marius as he sets out on his investigations and this one was no exception. I think this might be my favorite mystery so far in the series. It has so many layers and wrongdoers and the ending was a bit of a surprise. My only problem with these books is the character of Bella. I just wish the author would do something with her. So far she's just there to provide Marius with the connections he needs to solve some of the crimes. She barely does anything in the actual investigations. I have also grown tired of the way Marius holds her up on a pedestal as this perfect person because that also doesn't allow her to become anything more than a pretty face. It also would have been better to have Bella and Gilbert's relationship come to a close in another way. If she ends up with Marius it will only be because his competition was taken out of the game altogether. I am holding out hope that the author will make some course corrections in future books. All of that being said, my issues with the writing to not extend to the actual plots of the stories and this continues to be a favorite series of mine right now.

I live for the author’s notes at the end of every installment of this series.
This is such a fun and well-plotted mystery series, and the latest installment is no exception. There’s not much going on in terms of significant setting this time around, but Brown still manages to make the story feel atmospheric and immersive.
I appreciate that these are always fairly intricately plotted without ever getting so convoluted that you can’t possibly guess at the solve, and I also appreciate that Brown keeps it light while still stressing the significance of the mystery.
Like other books in the series, a good bit of this is based on a real case, and the fictional version certainly does the story justice.
As always, there are heaps of historical notes at the end of the book. Brown seems to think of everything in this regard, from the most minute but intriguing bit of trivia to the larger contextual significance of events in the book.
Reading these notes is almost more fun than reading the book itself, but mostly the appeal is that they go hand in hand so well, and that we get some delightful editorializing from the author as he takes us through his notes.
