But it aoon becomes clear that things are not what they seem . . .

A welcome interlude of calm has descended on Wrexford and Charlotte, though with three lively young boys in their care and an unconventional circle of friends and allies, quiet rarely lasts long. And sure enough, in the dead of night, an old acquaintance appears and asks for help.

In this latest Regency era mystery, Wrexford and Charlotte along with their inner circle begin investigating the murder of a scientist working on a revolutionary new communication technology, which quickly turns into a complicated scheme of political intrigue, stock market manipulation and the threat of war.

While I loved the first few books in this series, I didn't like the later ones as much. But this new one started to turn it around for me again. Yes, some of the issues I found increasingly annoying in the previous books are still present. The overuse of cliché idioms, the very black and white morals, how for some strange reason all the characters seem to constantly talk to themselves out loud. (Why? Is there some sort of quotation marks per page quota you need to meet?) Random capitalization of certain words like Life, Truth, Evil, Good, Right, Wrong. But overall, I enjoyed it much more than the previous one. It wasn't as bogged down in scientific explanations as I feared from my experience with the last few books in the series. While there were some passages explaining the Stock Exchange that I started skimming, overall it wasn't too info dumpy. And there were some very nice character moments which I felt were missing from the previous few installments. I quite like the new addition to their family. And I wasn't even as bothered in this one that the murder investigation once again devolved into a convoluted spy plot. I actually found myself interested in that aspect this time around.

If you've liked all the books in the series up until now, I'm sure you'll like this one too. If you've grown a bit disenchanted with the series over the last few books, this might or might not turn it around for you again. I'm definitely glad I gave it a chance. If you're new to the series, I highly recommend you start with book #1, Murder on Black Swan Lane. I don't think this'll really work well if you don't know any of the characters' history.

As a longtime fan of this series, it’s time for me to step away.
I found myself gritting my teeth and skimming through it, which is no way to read a book.

What once was charming and fresh has now become formulaic and grating. While any good series has a familiarity to concepts and characters, I feel like these have become a variation of ‘insert scientific advancement here, pair with precocious and large-vocabularied children, overuse words like ‘dastard’ and ‘varlet,’ throw in dubious neat coincidences and a large amount of ginger biscuits’ and you have this.

I will say that if you’re a fan of the Enola Holmes movies (I’m not), you may enjoy these more than me. I’ve lost interest in the Weasels myself, and the latter books seem more centered around them, which gives more of a YA vibe.

Thank you to NetGalley and the publishers for the opportunity to read and review this book. I’m sorry my review was not a favorable one, but it is an honest one.

The Wrexford & Sloane mysteries are one of my favorites, not just because of the suspenseful murder mysteries, but also for the family and friends Wrex and Charlotte have created. While they have no children of their own, they have the Weasels. Two street-smart urchins they are educating and raising as their own, along with a young man they have become legal guardians of. Charlotte & Wrex love these children as their own. Together with a close circle of friends from all walks of life, they solve mysteries.

In Murder at Somerset House, their circle grows with an unexpected young one. I loved watching them embrace this new family member and seeing them all work together to solve the murder of a society scientist. As they investigate, they uncover a plan to disrupt England's finances.

After the events of the previous audiobook, both Charlotte & Wren were hoping to step away from solving mysteries, particularly when the last one put them in grave danger. However, when presented with the facts and questions regarding an arrest that was made. Soon they uncover a plot involving the French and Napoleon.

I loved the tidbits about the stock exchange. Raven, who loves numbers, has gone to work with Cordelia on her calculations for a stock trader. We also learn quite a bit about homing pigeons as our newest family member has an affinity towards them. In order to solve this case, the Weasels' skills are put to use, and I dare say it was rather nerve-racking as they closed in on a suspect.

If you love character-driven novels with murder-mysteries weaved in historical tidbits, you'll want to devour this series. While each audiobook presents a unique case, I recommend listening in order for the romance, friendships and found family.

James Cameron Stewart narrates the series and has become the voice of these characters. The story lends itself perfectly to the audio format and is my preferred format for this series. This review was originally posted at Caffeinated Reviewer

Traitors, murder and high finance!

In which Charlotte and Wrexford gain a new resident!? Such a lot is happening here.
The weasels somewhat reluctantly have a new member join their group.
A British scientist is killed at Somerset House, and Charlotte and Wrex are asked to investigate. Napoleon escapes Elba. Raven learns more about economics, bonds and the stock market.
Danger is everywhere. The weasels narrowly escape death. Wrex is hard put to keep his extended family safe. There’s a traitor highly placed divulging secret information.
A thoroughly “on the edge of my seat,” page turning read.
The author’s notes are fascinating. Penrose declares her research led her down to various interesting blackholes, and her attention to detail is a thing of beauty.
Another fabulous read from Penrose!

This story takes place after Napoleon has been sent to Elba but before the Battle of Waterloo. It is a time of upheaval and Wrex and Charlotte are waiting for the next shoe to drop. When Wrex is asked to look into the murder of the brother-in-law of an old acquaintance, the team finds itself deep in the machinations going on in England.

Atticus Boyleston was a member of the Royal Society and a scientist working on electricity and magnetism. He had more interactions with the Frensh scientists working on the same problem than his fellow British scientists are happy with in the time after Napoleon's carnage. He was in the process of making a grand announcement when he was murdered.

The British government has asked Wrexford not to pursue his investigation. They have reasons to want the brother-in-law to be considered the killer in order to give them time to find the real killer and figure out French agents are planning.

Wrex still investigates because he wants to find out about the scientific discovery the Boyleston was working on. Communication via electricity could make revolutionary changes in the way the world works, and it is in England's best interests that the French don't make the discovery first.

But this plot turns out to be a red herring. The French have a more dastardly plot in the works. One which disrupts the Stock Exchange to make it impossible for the British government to get necessary funds to fight against Napoleon in his new quest for the throne of France. Kit, Cordelia, and Raven are assisting a genius of the Stock Exchange with their math skills to prevent this plan from succeeding.

Adding to the intrigue and tension, Wrex learns one of his father's secrets which he had been intending to research before this latest crisis. It turns out that he has a young sister named Eddy who needs a home since her nurse/governess is dying. Twelve-year-old Eddy is mature and self-possessed and has a way with animals. She is also an orphan in need of a home.

This was another excellent episode in this series. I love learning more about the time as the author includes real historical figures along with characters needed to further the plot. I like the way Wrex and Charlotte are building their own found family. I liked the fast-paced action and the twisty plot.

I took a break from my current medieval romance obsession to read the latest Wrexford & Sloane mystery, & I kinda wish I hadn't?

The good (?):

- The phrase "ginger biscuits" only appears 11x in this installment (which is still probably 3x too many but a vast improvement over 17x in book #8, Murder at King's Crossing).

- *SPOILER* Wrex gains a heretofore unknown secret adolescent sister (Eddy), & the Weasels gain their 1st girl member! I really enjoyed the change in dynamic to this little group, & I suspect Raven has a crush. 😉

- Charlotte is marginally less annoying & insistent on doing stupid things, though IMO she has a very inflated sense of the impact her political cartoons have on the political climate of London... 🙄

- Wrex & von Muench (sort of?) become BFFs.

Now...other things...

- This book is a hot mess. 50% of it is devoted to chasing down the possible existence of an electric telegraph that in the end has nothing to do with anything. Terrible MacGuffin.

- Wayyyyyy too much info about electromagnetism & how telegraphs work that again, has no relevance to the plot.

- SO MUCH MATH. This book is exhaustingly mathy. I don't not care about stockjobbers (how they came to be & what they do), nor do I care about the stock market & its workings in 1815 or how the British government funded wars & empire operations thru loans. 😴

- Lest you think I exaggerate, the math. Soooooo much unnecessary math!! I just don't care how it works after a point, something needs to HAPPEN.

If old-timey math & MacGuffins to nowhere are your jam, go forth! Methinks Wrex & Sloane & I need a nice long break...though I'll still read the next (eventually), because WEASELS!! 😍

Another wonderful cozy mystery from Andrea Penrose. I always enjoy slipping back into the world of Wrexford & Sloane the historical detail, the clever plotting, and that mix of suspense and warmth that makes these stories so comforting.

This one had an interesting setup and plenty of twists to keep me hooked. The characters continue to grow in really satisfying ways, and I love how the found-family dynamic has deepened over the series. It’s smart, atmospheric, and just a great read overall.

Already looking forward to the next installment! Thanks to Kensington for the gifted book.

As usual Penrose writes a tight, suspenseful story. The story was engaging which I enjoyed. I love the addition of Merlin which adds more flexibility and interest to the family, this will really expand their ability to investigate. A clever plot addition by the author.

I love how committed Penrose is to historical accuracy. I always read her Author Notes since they prove to be interesting. However I find that there is a bit too much information on mathematics, science, stock market, etc for me. I grow quickly bored with the long, detailed explanations and will skip over whole paragraphs. Now this is my issue, not the author’s. I’m sure there are many readers who are interested and enjoy reading this type of information. It won’t stop me from reading this excellent series.

Just one last thing, can Penrose do a ‘find and replace’ on the phrase ‘Mac’s ginger biscuits’ please? It becomes tiresome to read it so often and in fact I’ve even considered making it a drinking game. lol. But seriously it seems as if there were a few less references in this book so I’m hopeful the next book will have even less of that overworked phrase (and please include ���feathered’ on that too.)

All that aside, I enjoy this series and I look forward to the series continuing for many more instalments.

When a controversial, innovative scientist on the cusp of demonstrating his new experimental breakthrough is murdered, the very security of the nation may be at stake for Lord and Lady Wrexford to solve the mystery of his death. Andrea Penrose’s dark, fascinating Regency Era mysteries continue to tantalize and engage even nine books into the series.

Murder at Somerset House presents a new standalone mystery, but also has a shocking answer to a personal mystery that has been ongoing throughout the series. There is a rich warmth of family connectedness that has built from book one as Wrex and Charlotte, the Weasels and their extended friends and family forge a found family and detecting partnership so these are amazing when read in order.

As usual, Andrea Penrose not only delivers a cunning murder mystery to solve, but wraps it in historical interest pieces of the day like the scientific exploration of electric-magnetism, early telegraphs, early stock market, economics, and also the political intrigue of Napolean’s 100 Days.

I found it fascinating how the mathematics that Raven and their friends, Kit and Cordelia work to flummox a French plot just as Wrex, Charlotte, and the others use all their talents to solve the murder. But, between all that a new personal matter comes to light and I was on pins and needles to see how much drama it would stir up and there is always the tension happening when Wrex and Charlotte doubt their decision to let their family in on the hunt when lethal danger is involved. It will be interesting to see how this alters things going forward with the series. The suspense built to a taut climax and then a satisfying end.

A solid series that remains strong and worth recommending to historical mystery fans.

I rec'd an eARC via NetGalley to read in exchange for an honest review.

I've been reading the Wrexford and Sloane mysteries since the start and have enjoyed them a great deal. The cast of central characters keeps growing and keeps becoming increasingly delightful. The tensions between social expectations and women-wanting-to-do-what-they-want-to-do-dammit-and-maybe-even-doing-it-while-they're-wearing-trousers are there, with convention acceded to only reluctantly and incompletely.

The cast of central characters are varied: wealthy former rogue member of the aristocracy who dabbles in chemistry; a woman once part of the 'ton' and now a political cartoonist, gradually and a bit reluctantly reentering the ton; a female mathematician; a feisty dowager; a manservant with a remarkable set of skills; a fierce and affectionate cook/housekeeper; and the weasels: three young boys adopted into this household. Two of the weasels are former street urchins, one now a budding artist and inventor, the other a mathematical prodigy. The third weasel comes from the aristocracy, but is orphaned and mixed race, and his nearest relative wants nothing to do with him, so he's been added the group. There's also a pathologist and a not-completely-trustworthy baron from the continent who keeps showing up unexpectedly. So, lots of variety, lots of opportunity for hilarity.

However, I'm finding it harder to sit comfortably with the fact that while some of the members of this household have risen in station to heights that might once have seemed impossible and have been warmly embraced, there's still a crew of unnamed servants making sure fires are lit and tea is served. Where do they sleep? When do they sleep and for how long? Do they each get their own bed or are they doubled up? Do they have windows to look out of? It's kind of a Brechtian "A Worker Questions History" moment. Not really a new issue at all, but one I've managed to miss in the past because I've been enjoying running around with the central characters.

Murder at Somerset is a solid historical mystery that anyone who enjoys the genre will appreciate. I'm just have my own little moment of trying to see beyond the center of the narrative and into the edges.

Interesting story, quite complicated. Looked like it was just going to be a murder but then it went into explaining how the stock exchange could be undermined with rumours, especially important on the eve of Waterloo. The weasels take a great part as do the Sheffield. I'd have liked a bit more of the relationship between Wrexford and Charlotte as I think that has gone off the boil a bit, probably realistically with the increase in their family. The new addition sounds interesting.

Informative.

Boyleston speaks to the Royal Society about electricity and magnetism. He is an English man, but has been working in France. Later that night, the speaker is found dead and a gun is found. Wrexford investigates with some help from the Weasels and discovers that the French maybe have figured out how to send messages over the air. Also, the gun was made by Mr. Egg, but he was definitely not the shooter. The weasels help to do some investigating. Wrexford manages to make sure that radio communications are not yet invented, but there are groups working on it. They all become worried when Napoleon escapes from Elba, and is immediately accepted in France. There also appears to be someone in the London government who is accomodating the French.

The reader is also introduced to a new weasel. Wrex's father's daughter has moved into the Wrexford home. She is very good with animals, and she becomes an additional weasel called Merlin. She is an expert horse rider, and can even manage Wrex's wildest horse. She also has pidgeons on the roof. She is very shortly a very important member of the family and very bravely goes to help rescue Wrex.

This is a great addition to the series, and I thank Netgalley and Kensington Press for the ARC so that I could read the book before publication.

Andrea really did her research on this mystery: electricity to the London Stock Exchange. Despite the fact I barely squeaked through economics in college, I found the explanations of the stock exchange fascinating. It all is part and parcel of Murder at Somerset House as Wrex and family seem to be going in circles to discover why a scientist was murdered. This investigation will have you spinning too!

This book is so methodically plotted. Red herrings all over the place! But what really humbled me was the fine details of the stock market and economics. I appreciated how the author had different characters explain and give teachable moments, but I was still left scratching my head, “huh?” I’m a librarian! I do words, not numbers! Otherwise, a great addition to the series. Thanks to Kensington for the ARC.

When I started receiving advanced reader copies of books to review, there were a couple of authors who immediately caught my attention. One of those is Andrea Penrose. I found the Wrexford & Sloane Historical Mystery series about the fourth book in, and immediately went back and read what I missed. Set in Regency England, the character of Charlotte Sloane was an interesting one. She was a strong, independent woman at a time when there were strict rules proscribing her behavior in society. The friendship turned into romance between her and Lord Wrexford felt natural, as there was a great deal about the two of them that worked. There were certain conciliations by Charlotte as she once again found herself part of the society she had rejected earlier in her life. However, she and Wrex have managed to carve out a good life while not surrendering their morals. They are also legal guardians of three boys. Two were street urchins who helped Charlotte when they were all living rather poorly. The third came to them after being rejected by his father’s family due to his skin color.

In the ninth book of the series, Murder at Somerset House, Penrose indicates in her afterword that she felt the need to shake things up a bit. The stories were descending into formulaic writing, and she wanted to avoid that. I have always said this series is Bridgerton for smarter people. The background is the beau monde of Regency England, but Lord Wrexford and Charlotte see it more as an obligation they have to navigate rather than enjoying themselves at various parties and soirees.

The big upheaval in Murder at Somerset House is an addition to the menageries of young people that Wrex and Charlotte take care of. Wrex learns he has a younger sister he never knew about, since he was estranged from their father when he died. Up until now, Eddylina has been cared for by a governess. That woman has fallen ill and can’t care for her any longer. There’s no doubt in Wrex’s mind that “Eddy” is his sister, as he sees too much of his father in her when they meet. Eddy has a natural ability with animals, including Wrex’s intimidation stallion, Lucifer.

However, the mystery at the heart of Murder at Somerset House has little to do with all of this. A fellow scientist is found outside of Somerset House after an evening where he had a public disagreement with the man who is arrested for his murder. Wrex is asked to investigate by the man’s cousin, who is sure his relative could not have done it. As Napoleon is making noise on the island of Elba, it seems the English government is worried the French have discovered the electric telegraph, which would give them a great advantage with battlefield communications should war break out again. Wrex, Charlotte, and their friends try to learn if this is the case. In the meantime, Raven works with Cordelia and a well-known “stockjobber” as they try to learn if the French are also targeting the English Stock Exchange.

Another solid addition for fans of the series. If you already love the characters and how history and science are woven together, you can forgive some of the pacing challenges. It’s dense at times with the stock market and electricity details. I’m not Cordelia or Wrex, after all. Yes it has infodump moments, but the mystery and tension are good. I still think new readers should read the first book or two rather than start here.

I still miss the tension and connection between Wrex and Charlotte from the earlier books. That head and heart combo was the soul of the stories, along with the science that drove the mystery solving. Now it’s the family as the whole that has the focus, but I find myself wishing for more page time with these two. I’m underwhelmed by the addition of yet another inner circle member. The ensemble cast is already pretty large imo. That said, I’m devoted and will be back for the next book.

I'm always exciting to read another Wrexford & Sloane mystery and find out what the Weasels are doing. Could there be another Weasel and what new inventions are headed our way? How could we speed up information instead of sending passenger pigeons? Maybe we can use pigeons anyway.

Napoleon on Elba, the London Stock Exchange, electro-magnetics it is all wrapped together to make a great read.

Now to wait for the next one and hopefully there is one as there is still so much potential there...

There is a lot going on in this new book about Wrexford & Sloane. There is the usual murder to get things started. Then the scientific connection which in this one is early work on the telegraph. Then there is a lot going on with the London Stock Exchange and how it is manipulated for big profits. And finally a new character is introduced to the family, this time a young girl who will probably have a great story line in future books.

It’s the year of historical suspense for me! I have really loved this series. Penrose writes engaging characters and stories and her plots are so well done. I will say that of all the books so far this was probably my least favorite. I just wasn't as engaged in the story arc. I do love seeing the evolution of the weasels as they grow and become more independent and the addition of a new member to the group was an unexpected twist.

You can’t go wrong with Wrex and Charlotte though and I look forward to learning more about Wrex’s father and what other mysteries and murders happen next.

Thank you to Netgalley, Goodreads and Kensington Books for a copy provided for an honest review.

This is the ninth book in the Wrexford & Sloane series, which follows an aristocratic scientist and satirical artist as they solve murders in Regency England. While the mystery in each story is stand alone, I do recommend that you start with the earlier books in the series to follow the relationship arcs that have developed over the course of the series from romance and family to friends and enemies.

This story brings more surprises for Wrexford and his family and more information about the mysterious “A”. The mystery begins with the murder of an inventor working on the (for that time questionable) connection between electricity and magnetism and their possible applications for military uses in communication. When an old acquaintance requests their assistance in the investigation after their brother-in-law is accused of the deed, our beloved family jumps into action with their own brand of investigating to uncover political intrigue and its financial consequences.

I really enjoyed the technological and political intrigues in this story. There’s a great subplot involving math, finance and the stock market at that time. It may have been a bit over my head, but I enjoyed learning about how the stock market worked back then. This historical mystery series is filled with good mysteries, intelligent characters and exciting adventures. I can’t wait for the next one.

I struggled a little with this entry into the series. While the mystery was good, it was a little convoluted, and the mathematical and stock exchange information felt a little like a data dump.

In the end, I'm glad I stuck with it because the end was well worth it.

It starts with the murder of a speaker at the Royal Society which the Wrexfords start to investigate. But foreign forces reach out to England ready to cause financial havoc. Family and friends become involved, when a secret from the family's past appears.
An entertaining and well-written Regency mystery with its likeable main characters which are supported by a cast of varied personalities. Another good addition to this enjoyable series.

Worst one yet. Mystery was terrible. I prefered the villain. He was lot more interesting than anyone else and he wasn't all that interesting to begin with.
The constant jumps from one set of characters and their dialogues to the other set was giving me whiplash. I was reading this as an ebook and in my copy there is nothing to mark the switch. It just continues as a new paragraf, but no additional space in between. And some dialogues continued mid discussion. It took a moment to remember what happened before, and switch to other topic.

There’s a saying that “War is diplomacy by other means”. The converse is often applied as well, that “Diplomacy is war by other means”. It’s also been said that “War is hell”, so either way, references to hell are certainly applicable in both cases. Which leads straight into the motivations behind many of the characters in this mystery, as espionage is more than capable of being even more hellish than either war or diplomacy, particularly in the hands of a desperate despot doing his damndest to get his power back and keep it.

But that’s not where the story begins, as the whole point of the espionage in this story is to obfuscate and obscure where and when it starts. Because it begins with the death of an irascible engineer who claims to be able to demonstrate a device that will revolutionize the world and change the course of history and the tide of battle in favor of whoever gets there first.

The story, and the convoluted plot at its heart, relies on a complicated string of macguffins that rely on the lack of the very development that they initially claim has already been made and in the hands of Britain’s most capable enemy.

That development is instantaneous communication – and it did revolutionize the world when it came about three decades later as the telegraph. But this story, its central mystery, and all of the tasty red herrings and countless plots and counterplots within it, rely on the fact that the technology of the Regency Era and the Napoleonic Wars has not yet quite reached the point where the theory of telegraphy can be fully translated into a working device – even though it’s clear to the scientific community that the day is coming within their lifetimes.

But this story relies on that technology being teasingly close but not yet manifest. The opening death of the thoroughly unpleasant engineer/inventor Atticus Boyleston was designed to confound and confuse the powers that be on every level in Britain, as this story takes place during Napoleon’s exile on Elba, and the world is watching because no one with an ounce of either sense or prescience believes that the deposed Emperor of France is planning to remain graciously in exile.

So it begins with Wrexford, coerced by friendship and duty, investigating a murder he’d hoped to stay out of. Unaware that his wards, the ‘Weasels’ have already drawn him in while chasing the whereabouts of an escaped monkey from the Tower Menagerie.

But once Wrexford and his wife Charlotte, along with their eccentric, extended family are in, they’re all the way in. And up to their necks, as the agent provocateur behind the entire plot has decided to kill as many of them as he can reach along with any desire Britain might entertain to re-engage in another expensive war with a newly re-instated Bonaparte.

Escape Rating A: I feel like I came into this one a bit sideways, because as much as I love this series, and I absolutely do, what hooked me this time around began with the real-world historical implications and applications. Specifically, it was the stuff about the telegraph. It teased me greatly that I wasn’t certain whether or not this was a bit early for the actual introduction of telegraphy. I knew it was close, but didn’t think it was quite there yet.

Which sent me scurrying to look up the real history of telegraphy, and kept me focused there in spite of myself. Because it’s SO CLOSE in this story. Not just that the device was close to coming to life, but that the experts and inventors that Wrexford and Charlotte consulted in their investigation were mostly real historical figures who really were experimenting with the thing at the time. And the whole thing of being on the cusp but not being able to get over the top was beautifully handled in all of its many eccentricities.

Then the mystery got bigger, broader and even more complex, as the focus shifted from the not-yet-existent telegraph to the very real but still very much in its, well, maybe not the infancy but certainly the childhood, of the London Stock Exchange. And again, while the actual attempt to raid the market did not happen, the story does a terrific job of explaining how the early stock markets worked, introduced a fascinating real-life character in the person of economist David Ricardo, expanded the vastness of the plot as a whole, AND began what will become an ongoing part of the series by setting the ‘Weasels’ on their respective paths to adulthood.

And manages to add one more ‘weasel’ to the crew into the bargain. All of these developments bode very well indeed for future entries in the series.

Howsomever, in spite of the threat to the entire Wrexford clan, brood, and extended menagerie, the part of this story that had me glued to the pages was the historical background. The time in which this story is set, the ‘100 Days’ of Napoleon’s brief return to power, was a pivotal period in history and a fraught, taut, probably terrifying period where Britain and its people were on the brink of a war that no one wanted to go through again. The tension is palpable throughout the whole book.

And it’s ironic that so much of that tension can be laid at the feet of the device, or the lack thereof, that kicks the story off. So much of what happens, how the plot works and nearly succeeds, how it’s ultimately foiled, is dependent on events that have already happened but are not yet known, which highlights just how much instant communication did and still does change the world.

I was every bit as caught up in the waiting game as the characters were, even though I already knew the outcome. Which kept me cross-checking between the dates IN the story and the history to see where the stresses and strains were relative to the relief that was about to come.

I’ve frequently compared the Wrexford & Sloane series to the Sebastian St. Cyr series because they cover this same time period from slightly different angles – and that is especially true in this case. St. Cyr actually takes two books to cover this same set of historical circumstances, When Blood Lies and Who Cries for the Lost. And they are just as riveting as Murder at Somerset House. So if this series appeals to you, that will too, and very much vice versa.

This reader, at least, is very glad that the books in the St. Cyr series are usually published in the spring, and the books in this series publish in the fall – so I always have one to look forward to. Just as I’m already looking forward to the TENTH book in the Wrexford & Sloane series this time next year, to see what mystery they have to solve and what trouble the Weasels have managed to get themselves into!

The murder at Somerset House by Andre Penrose, it’s a refreshing read from what I always read, I enjoyed the 19th-century setting, and I found it quite elegant and interesting.

When there a murder accusations in town an incident sends Charlotte and Lord Wrexford into
Investigation creates yet another crisis and suspense.

The novel deepens with complex characters and plot twists that even I didn’t see coming, I would hate to give spoilers to anyone

This novel is a fresh mystery, that is beyond a typical drawing-room mystery

I would suggest this to fans of historical mysteries and I hope you guys find it as interesting as I did.
