There’s so much glamorization of past eras which, frankly, were probably, all-too-frequently, anything but.

I’ve done it, you’ve done it.

The Regency era, though, certainly wasn’t without its charms.

That showiness—of anyone who had a title, money, or was somehow positioned favorably—of the time, combined with the delicious intricacies of what was (and was not) acceptable, have made for compelling reading in more modern ages since... well, the Regency, when Austen, and others, were penning their tales (of men with fortunes in want of wives, and whatnot).

The clothing... the manners... the balls and luncheons and teas and promenades... the rules that polite society (mostly) followed... We need look no further than the massive success of Bridgerton (both book series and Netflix show), to understand the widespread appeal of it all.

But what if something even more exciting than who had their hat set at whose fortune—like, say, an unsolved murder—were at play... with a rather striking and headstrong young woman responsible for figuring it all out?

Ah, in that case, you’d get the second in author Celeste Connally’s series about just such a gal, All’s Fair in Love and Treachery.


When you’re an invited guest to the court of Britain’s Queen Charlotte, you know a couple of things.

You’d best be on your very best behavior... and your reply should always be “yes” to whatever the queen asks of you.

So, when Lady Petra Forsyth finds herself in that very position, and the queen requests that she get to the bottom of a murder(!) at the Asylum for Female Orphans—the untimely demise of the orphanage’s matron, herself—she readily acquiesces.

But, after just a small amount of digging, Petra is disheartened. There are three prime suspects: one of the older orphaned residents of the home, the woman who was second-in-charge, and one of Petra’s own dearest friends, a generous patroness.

Nonetheless, when Queen Charlotte tasks you with a duty, you fulfill it, so Petra soldiers on... only to find that her not-so-secret paramour, one Duncan Shawcross (another favorite of Her Majesty, in a performing-of-clandestine-missions sort of way) is also somehow involved.

But, when Petra tries to find him, she discovers that he has also disappeared... with one of the few clues—a letter, which one of her sources claims to have seen—missing, along with him.

With a plot that grows increasingly complicated by the moment—traversing London, on a quest to find missing persons, waylaid missives, and put a stop to what sounds more and more like a deadly mutiny directed at the very monarchy, itself—Petra, along with a group of friends, acquaintances, and even enemies, engages in a mad race against the clock.

Because as surely as London is currently in the midst of a once-in-a-lifetime, citywide celebration of Napoleon’s surrender at Waterloo, Petra understands that she, her friends, and the much-nearer powers that be are in grave danger of something far worse than any of them can imagine.


This was the first Celeste Connally book I’ve read, but I’m hooked.

Connally absolutely nails the Regency intrigues, manners, and pageantry—all the fun of the things long lost to us—while also imbuing it with a bit of modern sensibility.

Lady Petra is no shrinking violet... there’s nary a scene where she’s embroidering anything, nor playing a convenient pianoforte. Instead, she’s a smart, clever, and headstrong young woman, bent on forging her own path, on her own terms.

Definitely a woman whose exploits Ms. Austen would’ve enjoyed reading about, hmm?

And honestly, I can’t think of anything more delightful than that. All’s Fair in Love and Treachery is a wholehearted YES from me.

This historical mystery is an enjoyable read, though it has some flaws. Lady Petra, the main character, is a determined sleuth, but her impulsive decisions and the underdeveloped supporting cast can be frustrating. While the mystery itself is engaging, the pacing can feel uneven, and it helps to have read the first book in the series to fully appreciate the story (which I did not).

While promising, all's Fair in Love and Treachery is a historical mystery novel with a meandering plot and underdeveloped characters. The central mystery, intertwining the death of a viscount with a more recent fatality at an orphanage, is intriguing but bogged down by excessive repetition.
Lady Petra Forsyth, our amateur sleuth, is a conflicted heroine torn between her past and present. While her passion is commendable, her frequent distractions hinder her investigative prowess. Though serviceable, the supporting cast lacks depth and relies heavily on the reader's familiarity with the previous book.
The novel's pacing could be more consistent, with the crucial clues emerging abruptly in the latter half, feeling more contrived than cleverly deduced. While charming, the romance between Petra and Shawcross feels extraneous.
Despite its shortcomings, the story remains accessible, and the historical setting is well-realized. However, a prior reading of the first book is essential to truly appreciate the full depth of the narrative and its characters.

Thank you to St. Martin's Press | Minotaur Books and Netgalley for this ARC. I really enjoyed this book and read it in one sitting! I would definitely recommend this book.

I received a complimentary copy of this book, thank you to NetGalley, Minotaur Books, and Celeste Connally. Opinions expressed in this review are completely my own.

I couldn't read all of it, after about 30% of the story I began to skip around. What I found was just as uninteresting. I didn't like Petra, the lead character, or the other characters to be honest. The plot was more contemporary than historical and I felt it was forced into the genre when it would have been better off in modern time. Reading the first book would help a lot, it seems to pick up right where the first ended and it was confusing.

Celeste Connelly knows how to write a mystery that keeps you on your toes! I have been anxiously awaiting the second book in the series since the first one ended on such a cliff hanger. I’m pleased to report that the 2nd book in the series did not disappoint. I adore Lady Petra and her friends, and every chapter in this book had me flipping to the next page to see what would happen. Highly recommend for historical mystery fans.

I received the ebook and audiobook as Arcs from NetGalley. Thank you NetGalley!!

This book, like the first one, is a fun historical mystery with memorable characters that keep the story moving. The pros are definitely the overwhelming compassion and respect shown by the main character to everyone she meets, her tenaciousness and determination to solve the mystery and catch the bad guy, and the relationships among her friends. The cons - sometimes our FMC does the “I’m going to make a stupid decision that I know is dangerous, find myself in a perilous situation, and then act like I had it handled all along when someone jumps in to save me.” She runs right into situations that she should anticipate seeing as how she is this wonderful detective that solves murders and cracks open cases involving political subterfuge, spies, and well guarded secrets from the elite and wealthy. My other con is the openess of the female characters about their sex lives. I don’t doubt that it occurred but the amount of times they made statements about their sex lives in ear shot of so many others seems unrealistic. One of the characters seems to be doing an impression of Samantha from Sex in the City but in carriages and at balls.

The narrator was well spoken and fun to listen to. She provided just the right amount of sass and snark to our FMC and enough differentiation to the voices used for the other characters, that each was unique and distinguishable. 4 ⭐️

Thanks, Macmillan Audio and Minotaur Books, for the ALC and arc!

I needed the second book when I finished the first book in the LADY PETRA INQUIRIES series. One year is much too long to wait, but I have to say the wait for ALL’S FAIR IN LOVE AND TREACHERY was worth it. Lady Petra returned strong, smart, and snarky, and I love her so much. She also gets the best book blurb, “BRIDGERTON meets Agatha Christie in this dazzling next installment in a captivating Regency-era mystery series with a feminist spin.” Are you excited about her books now?

The ending of the first book solved a case but left us with a devious cliffhanger that surprised me. I started reading as soon as I received the arc because I had to find out what would happen. I missed the audiobook and ended up pausing my read until I got the new audiobook because Eilidh Beaton is such a good narrator for this series!! I love her voice for Lady Petra! Plus, her side characters are excellent! Reading is a splendid decision, but I adore this series on audio.

I love how quirky this series is. It truly is BRIDGERTON meets Agatha Christie. We get the gorgeous dress descriptions, the events of the ton, the tea, and then we get the crime-solving - sometimes in the silliest of ways!

If you’re a fan of either of the previously mentioned series, this is a series for you!

This is book 2 in the Lady Petra Inquires series. They can be read as stand alone novels, but you get more from book 2 if you read book 1 first. The narrator for the audio book is Eilidh Beaton and she did a wonderful job. She also narrated the first book, Think Like a Lady, Act Like a Lord.

Set in 1815, Lady Petra is requested to investigate a murder at the all female's orphanage by Queen Charlotte. Meanwhile, her lover and childhood best friend, Duncan Shawcross, is also working from a different angle on the same case. They cross paths but do they work together or pull against one another for the investigation?

I enjoyed the setting and the characters. I loved both Lady Petra and Duncan from the first book. The sub-characters are really fun to get to know also. I hope there are more books with some of them having a larger part in the investigating (or perhaps as suspects again). The one thing that always unsettles me on books such as this, with an outspoken female, is wondering how realistic it would have been. Way back when, I don't believe there were a lot of moments where a woman was allowed to speak her mind in public, so sometimes I get a little hung up on that. If you like the regency era time, you will enjoy this book.

Thank you for the copy, this is my honest opinion. Please be aware of any trigger warnings, as your mental health is most important.

I really wanted to like this book. While I enjoy some of the characters, there are still too many, which I didn't like about the first book. It becomes a chore to keep them straight, and then my mind isn't on the story. The mystery is pretty good.

Thank you to St. Martin's Press | Minotaur Books and NetGalley for providing an eARC of this book. All opinions are my own.

This is the second in the series and I find myself liking Petra and Duncan a lot more. There were a lot of characters and I am glad I made myself a character list as I needed to reference it often. In the beginning the head of the girls orphanage is found dead and Petra starts an investigation. She also finds a note claiming that Duncan murdered her fiance, Emerson. There was a lot of intrigue that at times i found hard to follow and familial connections that were all eventually explained.

I would like to thank Netgalley and St. Martin's Press for providing a digital copy

The sequel was enjoyable and provided more insight into Petra's long-lost fiancé as well as her current love interest.

The mystery was well-crafted and kept me engaged throughout.

I still absolutely adore Sable—what a standout puppy!

The dynamic with the Duchess manipulating Petra was intriguing, especially since some of the seemingly innocent characters weren’t entirely forthcoming with her. I didn’t quite understand why they insisted on her piecing things together on her own. I’m particularly looking at the Duchess and the main male character here.

The ending tied everything up nicely, with some unexpected twists and turns that genuinely surprised me.

Overall, I had a great time with this book!

Thank you to Minotaur books and NetGalley for the ARC of this book. All opinions are my own.

This was so much fun! I love this series and this one was even better. Whenever I’m deep into fantasy and need a break, I grab a mystery and this was the perfect solution. I love Celeste’s prose and I can’t get enough. Petra was such a fun character to follow and I loved that this is a historical mystery. It was so fun to read. I read it in two sittings. I definitely think if you’re a mystery or historical fan, you need to pick this one up!

"Since I have declared myself as never wishing to marry, I have often heard others saying I wish to be a nosy busybody instead. And that means few will think twice when I ask all the questions I like.”

Just like in Act Like A Lady, Think Like A Man, Lady Petra Inquires #1, people, specifically men, underestimate the prowess of Lady Petra's sleuthing skills in the new All's Fair In Love And Treachery, Lady Petra Inquires #2, by the cleverly skilled author, Celeste Connelly.

While London is celebrating Napoleon's surrender at Waterloo, Lady Petra is having her own internal war. She's uncovered evidence that the death of her beloved fiance 3 years ago was not accidental but murder! Worse, the killer is likely her secret lover Duncan; who is nowhere to be found at the moment.

Only Petra would think the best way to take her mind off this new development is to honor the Queen's request to look into the death of the matron that ran the Asylum for Female Orphans. Like the board game Clue, the matron was struck in the head with a candlestick laying next to her. Her investigation finds not only unsavory happenings at the asylum but a plot to overthrow the monarchy.

All this turmoil is delightfully performed by voice actress Eilidh Beaton, who as in the book 1, gives Petra her spunk with a wink to us that she knows she's smarter than these scoundrels.

I adore reading and listening to this series. This writer encompasses not only a fine Agatha Christie type mystery but a sultry Bridgerton scandalous love affair. At the same time she lets us know that in a man's world a Lady knows All's Fair In Love and Treachery.

I received a free copy of this book/audiobook from the publishers via #NetGalley for a fair and honest review. All opinions are my own.

All's Fair in Love and Treachery by Celeste Connally allows Lady Petra to realize that things aren't as they seem.

Can Lady Petra focus on her royal assignment? Or could the two cases be connected?

Lady Petra gains a critical piece of information from her last mystery, and she can't believe her eyes when it reveals that Duncan Shawcross might have killed her, believing Emerson. Petra has a lot of puzzle pieces that she has to sort through. I love how Petra can put the puzzle pieces together in her head as she gets more of them throughout the book. Petra is a sensible character who solves a case by getting people to talk to her. Lady Petra goes through the wringer of emotions as she tries to figure everything out, and I believe this was a good way for her to finally put her past to rest with Emerson.

The Mysteries
Lady Petra finds out that Emerson was murdered before being pushed down the stairs three years earlier. Now, she has to solve the death of the matron of the Asylum for Female Orphans since the Queen thinks radicals are up to no good with the orphanage. Petra needs the help of her friends to solve these cases. They find a lot of clues, and Petra starts to connect them. I have to say that I thought Emerson might still be alive for a minute there. Ms. Connally had me stumped on this one for quite a while.

Five Stars
Lady Petra, Duncan Shawcross, and the rest of their friends have successfully stopped the radicals while solving two cases simultaneously. My rating for All's Fair in Love and Treachery by Celeste Connally is five stars. If you love the Regency era with some mystery, you should try this series! Ms. Connally has written a fabulous set of characters, and I can't wait to see what her next case will be about.

I voluntarily reviewed an Advance Reader Copy. This does not affect my opinion of the book or the content of my review.

Those who try to solve the mystery before the characters will be thoroughly stymied by this one. Good luck! This was a delightfully complex mystery and a worthy second book in the Lady Petra series by Celeste Connally.

Enjoyed this one very much, another great historical cozy suspense from author Celeste Connally. Never disappoints, highly recommend!

All's Fair in Love and Treachery by Celeste Connally is the second in the Lady Petra Forsyth mystery series. As England celebrates the victory over Napolean, Lady Petra is embroiled in trying to find out if her lover iis connected with a plot to overthrow the Monarchy. The story and depictions of both upper and lower classes of characters is well done.

What a fun historical romance with a strong female lead! Lady Petra has proven she's got a knack for solving mysteries, so the Queen requests she help investigate a recent murder she believes is connected to threats against the monarchy. While Lady Petra is investigating the murder, she's forced to confront intertwined mysteries of how her love, Duncan, might be involved -- is he the man she thought he was?

I loved Lady Petra's fearlessness, her friendship with the circle of women she surrounds herself with, and most of all, the way she's not afraid to be independent at a time when that wasn't the norm. Highly recommend this book and this series!

This book is a delightfully twisty regency mystery!

As a reader who enjoys both historical fiction and mysteries, I found myself thoroughly entertained by Celeste Connally's latest addition to her Regency-era mystery series. Set against the backdrop of Napoleon's defeat at Waterloo in June 1815, the story follows the clever and determined Lady Petra Forsyth as she unravels multiple mysteries that hit surprisingly close to home.

Connally does a good job of weaving together the various mystery elements. The central investigation into the death of a matron at the Asylum for Female Orphans cleverly intertwines with Lady Petra's personal history, creating layers of intrigue that kept me guessing for most of the book. While some of the plot twists in the book require a healthy suspension of disbelief, the entertainment value more than makes up for any stretches in plausibility.

Connally's writing maintains a broadly Regency tone while creating characters with modern sensibilities. While this might be a drawback for some, it also keeps the story accessible. The dialogue is sharp, and the mystery unfolds with enough red herrings and genuine clues to keep readers engaged. While Lady Petra feels somewhat anachronistic for the time, she makes for an appealing protagonist whose personal struggles add depth to the mystery-solving elements. Her determination to protect both the orphaned girls and the monarchy, even while dealing with her own grief, showcases her strength of character.

Despite requiring some suspension of disbelief, "All's Fair in Love and Treachery" delivers an entertaining read that successfully combines historical romance with mystery elements. While the story takes a bit of time to get going, the way the personal and political plot lines mesh together creates a satisfying whole that kept me turning pages until the end.

Thanks to NetGalley for the ARC in exchange for my honest review.
