NATIONAL BESTSELLER • November 1933. London. Seven people receive mysterious letters. Someone knows their terrible secrets. They are summoned to a posh townhouse where one is stabbed right in front of the others, but somehow no one saw a thing. Can you help Scotland Yard solve the mystery?
A “delightfully witty interactive mystery packed with theatrical characters and exciting twists” (G.T. Karber, author of Murdle) from the bestselling author and illustrator of Your Guide to Not Getting Murdered in a Quaint English Village
Dear Detective,
Surely you have seen the papers and read about the dreadful murder of the American novelist—stabbed while in a room with six other people, and yet no one went near him or saw the murder occur. The crime is so devious, so logistically impossible, that it seems to have been committed not by a person but by a disembodied hand.
I must confess that we are at a loss. Who wrote the poison pen letters that lured these seven people to this deadly gathering? A poet, an earl, an actress, a cook, a telephone operator, and a lothario . . . What do they have in common? And how could a man be stabbed in a room full of suspects, even though no one went near him or saw a thing?
We have had our best people on the case, Detective, and we still can’t make heads or tails of it. We are giving this case file to you. Can you decipher the clues, decode the witness statements, and identify the murderer? You are our last hope. Can you help us crack the Creeping Hand Murder?
Yours truly, Detective Chief Inspector of the Metropolitan Police
in truth, i appreciate mysteries in theory, but i'm truly bad at guessing their solutions and it makes me defensive. in that way it's possible there was no way this reading experience could go right.
i did really like the pictures, and this would probably be a fun book to gift. (sharing these two statements both because i feel them and for your use as future backhanded compliments for reads you are not enjoying.)
i do like maureen johnson's mysteries in other scenarios — or possibly i just like the vibes of them? — but it's hard to say if this is really not that entertaining or if it’s only boring to me because i’m bad at this sort of thing.
for ego reasons i’m going to say both.
bottom line: i failed the detective job interview and all i got was a blah time.
As a devoted Truly Devious fan (I’m counting down to the sixth book next April), I couldn’t resist this illustrated, locked-room whodunit that dares readers to play detective. The minute I saw the Clue-style setup—maps, notes, and juicy little visual breadcrumbs—I was in. Full disclosure: I would 100% barter for an early copy of Turly Devious 6; I’ve even joked about loaning out my husband as a guest chef or unpaid intern—he’s elite at espresso runs and photocopier wizardry—if it would get me an ARC.
This book is pure puzzle-lover bliss. It invites you to slow down, scour the art, and assemble the case like a corkboard queen/king. My Scorpio rising “spidey senses” were tingling from page one, and yes, I clocked the culprit early—but solving it didn’t ruin the ride. The interrogation scenes had me snort-laughing, yet the tension stays taut; that pitch-perfect Maureen Johnson blend of dark humor and genuine stakes absolutely sings. She’s so good at sliding from comedy into catastrophe and back again that you feel the thrill of the reveal and the sting of the fallout.
If you’re itching to test your sleuthing skills and want a zippy, smart, highly interactive locked-room mystery, this one has your name all over it. Grab your highlighters, trust your instincts, and happy hunting.

It’s London, 1933. Seven people receive anonymous letters telling them to be at a specific address at a specific time or their secrets will be revealed. When they show up, most are known to each other. They have a drink, then the police arrive, but none of the seven has called them . The police have been told there has been a murder and there has been. One of the seven has been stabbed…while all the others were in the room…and no one saw it happen.
You are asked to take on the case and through photographs, interview transcripts and all kinds of mixed media you are to solve it. Can you do it?
This was very cute. I love mixed media books. If you are paying close attention (which I wasn’t….shocking!) the clues are there to allow you to make a good guess at the murderer. It’s a fun way to spend a couple of hours. Teens would like it.
The concept of this solve-it-yourself mystery (think Ellery Queen or Encyclopedia Brown) could not be more brilliant. The reader has access to witness statements, primary documents, illustrations, maps, photographs — everything you’d think you need to solve the crime.
Unfortunately, the ending is so convoluted that few could possibly guess the answer. Five stars for the concept and the many pieces of evidence; another five for Jay Cooper, the wondrous illustrator, but only one star for the execution of the ending. Let’s just call it three stars.
In the interest of full disclosure, I received this book from NetGalley, Clarkson Potter and Ten Speed Press in exchange for an honest review.
Some of my book club friends and I are big fans of Maureen Johnson's Truly Devious mystery series, so we when saw this book was coming out, we planned a mystery solving day! We all got copies of the book, color coded snacks, and spent 5 hours reading and discussing our theories about the mystery. We didn't solve everything but we had a strong suspicion of the murderer and had figured out a lot of the pieces of how it was done. I highly recommend doing this book as a buddy read with a least one or two other friends- I would not have gotten as far as I did or had as much fun with it as I did on my own.
Seven people receive mysterious letters. Someone knows their awful secrets. They are summoned to a posh townhouse where one person is stabbed right in front of everyone, but somehow no one saw a thing. Can you help Scotland Yard solve the mystery?
This is the coolest little book! It has illustrations, interview transcripts, articles, maps, photos and mixed media content. It brought the story to life. This was also funny at times.
Perfect for fans of Agatha Christie, Clue and Knives Out. Can you solve the murder?
Thank you to MBC Books, both authors and Ten Speed Press for my gifted copy.
4 stars - a fun little mystery story here in YA author Maureen Johnson's "You are the Detective: The Creeping Hand Murder" which is a short read full of illustrations and helpful (and red herring) clues to a 1930's London-set murder that occurs right in front of a group of people who've all been brought together with "poison pen" letters with various allegations. So "whodunnit"??? You, the reader, are invited to follow along with the Inspector and try. The answer is helpfully provided at the end, all tied up with a bow. This is a pretty cute book that should appeal to most mystery fans and I was, of course, reminded of the author's previous & similar one about "How Not to get Murdered in a Quaint English Village", so other fans will also enjoy it.
This isn't your average murder mystery, as the title suggests the reader themselves are the detective. When anonymous letters are sent to a group, summoned to a posh townhouse and one of them is murdered, with everyone claiming no one went near him all night, it is up to the reader to determine the culprit.
Inside this book, you won't find prose or long paragraphs. This book and story is told entirely in mixed media. A collection of drawings, photographs maps, letters, interviews are what awaits.
It is a very unique book. I would give this a 4.5 for concept and a 3.5 for execution. I did manage to figure out who the murderer was.
Pick it up if you're wanting a challenge.
Thank you to NetGalley and Ten Speed Press for providing an ARC copy in exchange for an honest review. All opinions are my own
A stunning presentation from a contemporary author of a perfectly plotted and tautly woven Golden Age "locked-room" Mystery! Plenty of puzzling, argument, humor, Secrets, even romance. "No, nobody here is dead! Of course not!" Surprise! This tale is so finely put together that only a genius could puzzle it out--and maybe not then. Absolutely adored it, and can't wait to reread it! Such a thrill!
I received a copy of this book for free for promotional purposes.
What a fun book!
This is not your traditional murder mystery book since it’s not written in a novel format. Instead, you are given all the pieces to solve the mystery yourself. These included pictures, interview transcripts, notes, maps, newspaper articles, etc.
As for the mystery, it’s historical fiction (it takes place in 1933 London) and seems to be in between young adult and adult.
I loved how the whole book was written. The pieces of evidence were engaging, and sometimes very comical. The interviews were often funny and the notes/maps/photos from Special Constable Nigel Stickley were hilarious.
I was not able to solve the mystery which is unsurprising since I’m always terrible at solving them. I was not expecting to solve it. Luckily the book does include the solution at the end. The solution is in a sealed envelope at the back of the book, which was a nice touch.
I read this book solo, but it would also be fun to read with another person or a small group.
Overall, I had a blast reading and attempting to solve the mystery. If you love mysteries and want to test out your detective skills, definitely give this book a try!
Read through this out loud with a friend and we had such a good time. It definitely elevated the whole experience, which was already fun to begin with - all of the various illustrations that imitate articles, photos, and drawings, coupled with the transcripts of the interviews are presented to you to figure out the mystery of the murder.
It's actually quite complicated. I'm pretty happy with all that we were able to take note of and connections that we made. We mostly had the sequence of events and murder pinned down. Mostly.
The characters were very funny at times, I honestly didn't expect to laugh as much as I did. A few things we expected more of? But the overall experience was great.
I'm just satisfied I was correct about the cats (not a spoiler).
this was really fun! the story itself is a fairly traditional murder mystery but it's not written in a straight-forward novel format – the reader is the detective and is given the material to solve the murder themselves: the material consisted of pictures, interview transcripts, newspaper articles, sketches, maps etc. and all of them include clues that help you solve the mystery. the solution is in a sealed envelope in the back of the book. I only half-guessed the correct solution without help but I still had a very good time trying to do so! a great read for a cosy winter evening.
WOW. As a reader this is a real treat!! It’s a buffet of classic mystery tropes and traditions: fair play, impossible crime, closed circle. All in a quirkily-illustrated 1930s setting with delightfully kooky characters.
I am pleased as punch to have gotten the killer correct, even though I got plenty of other details mixed up. There is a nice balance of clues vs red herrings, though it was not as buttoned-up as I expected. I have at least one lingering question. Message me and we can talk about it…
To address another reviewer’s complaint about the complexity of the solution: IMO it *is* possible to solve at least part of it. But you must be paying attention, and it certainly helps to reread it. The clues are there!!!
RATING: Despite the cute drawings, please note that cocaine is a big theme here. Probably best for adults.
(Why did it take me 3 months to read this? Well, I read a low-res digital galley very quickly, taking notes, and reread it once I received a physical copy. THEN I worked through most of the solution and finally read the ending. I hope it will not take you quite so long.)
I absolutely loved this Solve-It-Yourself Mystery! The plot and characters are fun and the illustrations are amazing! The mystery takes place in London in 1933. The reader is the detective and is summoned to a house where an American author was stabbed, but none of the other guests saw it happen. The book included interview transcripts, maps and diagrams, illustrations of the crime scene and more to help you investigate.
I had so much fun going through all the clues and trying to solve the crime. I was able to put some of the clues together, but the solution was more complicated than I had expected, and I didn't figure it out. There is a sealed envelope inside the back cover that has the explanation of the crime, presented in a very clever way. I didn't come up with all the answers, but was correct on a few things and most of all, I had so much fun with this book!
I received a copy of this book from MB Communications and Penguin Random House for review consideration. My review is voluntary and unbiased.
Fans of mixed media murder mysteries (like myself) will enjoy this brief little story. A group of people all get poison pen letters telling them to show up to this guys place alone, and then one of the guys is murdered in the middle of the room somehow with no one noticing. How? Who? Why?
I did find the motive to be a bit lacking, and I thought it would be more immersive due to its title, but it was just a standard mixed media murder mystery. Easy to pick up and read in an afternoon!
Thank you to the publisher for granting me access to an ARC via NetGalley in exchange for an honest review. All opinions remain my own.
I really enjoyed the very unique format of this book—it’s unlike anything I’ve read before. The use of art, graphics, and illustrated photographs gives it a visual energy that makes the experience feel interactive and immersive. Structured as a collection of photographs and interview notes, the book follows what seems to be an impossible murder, and you, the reader, are tasked with examining the evidence and drawing your own conclusions.
Although I didn’t correctly guess the murderer, I had a great time trying! This was quite a lark—clever, engaging, and visually compelling.
Thank you to NetGalley and the publisher for the opportunity to read and review this inventive mystery.
Très cool et bien construit, et même si j'ai bien déduit une bonne partie de la séquence, je me suis faite avoir par des red herrings et je me suis trompée de personne.
I loved the mixed media story and the way it slowly unfurled, allowing the reader to pick up the crumbs dropped by the author along the way. The absolute best though was the inclusion of drawings to illustrate various points in the book, like the content of the witnesses'/potential murderer's pockets, the broken window in the kitchen of the manor where the murder took place. Everything just added to the atmosphere of this murder mystery set in the 1920s.
Many different people coonvene at the house of one debonair socialite with a poisoned pen letter in hand, looking for explanations. While there and trying to sort out the mess, one of them gets murdered with an ice pick under everybody's eyes but nobody saw anything. It is then left to the reader to investigate sling with the detectives and figure out the whodunit.
Of course I didn't, but that's no surprise because although I'm a diehard fan of detective stories, my powers of deduction are not up to snuff. However, the story was so well-written and engaging, I thoroughly enjoyed myself. Maybe you'll solve it, so definitely give this one a go.
If you love Maureen Johnson or Agatha Christie, this book is for you. And if you don't, I'm sure it'll win you over.
4.5 Take a stab at being a detective for a moment in Maureen Johnson's fun little novel You Are the Detective: The Creeping Hand Murder.
In a room full of people, one man dies without any of them leaving their chairs. How can this be? In a multi-media format, readers go through each suspect's belongings and interviews. Johnson gives us funny and twisted British tropes with flair and Cooper provides fun and demented illustrations. At the end, you can deliberate and then open the final papers to reveal the killer yourself.
This was a fun read that made me quite annoyed at my husband and children for their many interruptions. I loved the format and layout of this book and only could have enjoyed it more if it was right in front of me in print so I could have more easily flipped back and forth to re-read or review evidence for a second time. Needless to say, I didn't even bother attempting to solve this and just ripped open the final answer pages like an animal, but, then again, I have never considered myself much of a detective.
Thank you NetGalley and Ten Speed Press for this ARC
this murder mystery provides you with all the interviews, reports, and photographs that you might need to solve who did it on your own. I had a lot of fun with the style of book itself, but I was really frustrated and underwhelmed with the conclusion. gonna put some of the reasons why- and what I thought the ballpark resolution was going to be- under spoiler tag!!
so yeah, just really disappointing compared to the clues I THOUGHT we were getting, and I felt like at that point, it could have just been anyone.
