Reading a great murder mystery is entertaining, but some books ask more from you than simply following the detective. They hand you the evidence, introduce the suspects and challenge you to identify the killer before the solution is revealed.
The best murder-mystery puzzle books turn readers into active investigators. Some contain logic grids, codes and visual clues, while others use emails, interview transcripts, police reports and nonlinear storytelling to hide the truth in plain sight.
This list includes both interactive puzzle books and cleverly constructed mystery novels for adults. Whether you want dozens of short cases or one elaborate crime that takes an entire book to unravel, these mysteries will test your observation, reasoning and deduction skills.

1. Murdle: Volume 1 by G. T. Karber
If you want a true murder-mystery activity book, Murdle is the best place to begin.
The book contains 100 miniature murder cases that must be solved using logic, deduction and process of elimination. Each mystery presents a group of suspects, possible weapons, locations and clues. Readers use an accompanying grid to determine who committed the crime, where it happened and which weapon was used.
The cases gradually become more complicated, making the book accessible to beginners without becoming repetitive for experienced puzzle solvers. There is also a loose narrative connecting the mysteries through Deductive Logico and his rival, Inspector Irratino.
Murdle became a major publishing success by combining the deductive structure of Sudoku with the appeal of a classic whodunit. The first volume progresses from elementary cases to “impossible” mysteries, and additional volumes are available for readers who want more.
Best for: Beginners who enjoy logic grids, Sudoku and short daily puzzles.
2. The Murder Mystery Club Puzzle Book by Gareth Moore and Laura Jayne Ayres
Instead of offering a collection of unrelated cases, The Murder Mystery Club Puzzle Book uses more than 70 puzzles to construct one larger investigation.
When a member of the fictional Murder Mystery Club dies under suspicious circumstances, the surviving club members begin searching for the killer. Readers must solve codes, logic problems, word puzzles, maps and visual challenges to uncover new clues.
The variety makes this an excellent choice for people who want more than deduction grids. Every completed puzzle advances the investigation, creating the feeling that you are working alongside the amateur detectives.
The puzzles range in difficulty, but the book remains approachable enough for casual solvers. Its combination of an ongoing story and different puzzle styles also prevents the experience from feeling like a standard activity book. The publisher describes it as one crime told through more than 70 interconnected conundrums. Andrews McMeel Publishing
Best for: Readers who want multiple types of puzzles connected by one mystery.
3. Cain’s Jawbone by Edward Powys Mathers
Cain’s Jawbone may be the most intimidating murder-mystery puzzle ever published.
Originally created in 1934 by crossword compiler Edward Powys Mathers, who wrote under the name Torquemada, the book contains 100 pages printed in the wrong order. The reader must determine the correct sequence while also identifying the murderers and their victims.
That sounds simple until you begin. The narrative is filled with literary quotations, obscure references, wordplay, changing narrators and deliberately misleading transitions. Because almost any page could seemingly follow another, solving the book requires close reading, research and an enormous amount of patience.
This is not a traditional mystery novel that can be read from beginning to end. It is a literary artifact that must be dismantled, rearranged and decoded. Only attempt it if you are prepared to take notes, move pages around and spend weeks—or longer—searching for the solution.
Best for: Expert puzzle solvers looking for an exceptionally difficult long-term challenge.
4. Can You Solve the Murder? by Antony Johnston
Antony Johnston combines a classic whodunit with the branching structure of a choose-your-own-adventure book.
You assume the role of a detective investigating the death of a businessman at a secluded wellness retreat. Instead of following a predetermined investigation, you decide which witnesses to question, which locations to search and which leads deserve attention.
Those choices send you to different sections of the book. A promising lead may reveal important evidence, while a poor decision can waste time or take the investigation in the wrong direction. Ultimately, you must gather enough information to accuse the correct suspect.
The interactive structure makes this a strong choice for readers who want more control than a conventional mystery provides. It also has replay value because you can return to earlier decisions and explore different investigative paths.
Best for: Fans of choose-your-own-adventure stories and detective games.
5. You Are the Detective: The Creeping Hand Murder by Maureen Johnson and Jay Cooper
Set in London in 1933, You Are the Detective presents its mystery as an illustrated collection of evidence.
Seven people receive threatening letters and are summoned to a townhouse. During their meeting, one of them is murdered in front of the others—even though no one claims to have seen how it happened.
Readers must examine witness statements, room layouts, police communications, letters and visual clues to reconstruct the crime. The book is designed as a self-contained case file, meaning the information needed to identify the killer is somewhere in the supplied evidence.
The visual presentation is especially important. Small details in the illustrations may be just as revealing as the written testimony, rewarding readers who carefully compare every account and image.
Best for: Visual learners who want an immersive, dossier-style investigation.
6. Murder in Tinseltown by Max Nightingale
Murder in Tinseltown takes readers into the glamorous and dangerous world of 1950s Hollywood.
You become the investigator and make decisions about which suspects to follow, what questions to ask and how to interpret the evidence. The investigation branches according to your choices, and incorrect conclusions can lead to failure.
The Hollywood setting gives the book a distinctive atmosphere filled with movie stars, studio secrets and people carefully protecting their public images. It feels like stepping into a vintage film-noir mystery in which everyone has something to hide.
Because your decisions influence how the case unfolds, this is more interactive than a typical whodunit. It is a good next choice for anyone who enjoys Can You Solve the Murder? but wants a more cinematic setting.
Best for: Readers who enjoy film noir, old Hollywood and branching mysteries.
7. The Game Is Murder by Hazell Ward
Hazell Ward places the reader directly in the role of the “Great Detective” in this ambitious, self-aware mystery.
The book asks you to reinvestigate a notorious unsolved case from 1970s England. You must listen to witnesses, study the evidence and provide a complete explanation of who committed the murder, how it was done and why.
However, the investigation repeatedly challenges your assumptions about the case and the people presenting it. The novel plays with the rules of classic detective fiction while speaking directly to the reader and questioning the relationship between a mystery writer and the person trying to solve the crime.
At 464 pages, The Game Is Murder offers a substantial narrative as well as a puzzle. It is less like completing an activity book and more like entering a long, unpredictable battle of wits with the author. Penguin Random House
Best for: Experienced mystery readers who enjoy metafiction and complicated narrative tricks.
8. A Most Puzzling Murder by Bianca Marais
Destiny Whip has spent her life avoiding Eerie Island, the strange place where she was abandoned as a baby. When the island’s residents ask her to investigate an impossible murder, she is pulled into a locked-room mystery filled with riddles, secrets and questions about her own past.
The novel incorporates puzzles that readers can attempt alongside Destiny. Its quirky characters and unusual setting make it lighter and more playful than many traditional locked-room mysteries, even as the central crime becomes increasingly complicated.
This is a good middle ground between a standard novel and an activity book. Readers receive a complete story, but the puzzles create opportunities to participate rather than passively wait for the detective’s explanation.
Best for: Readers looking for a whimsical locked-room mystery with interactive elements.
9. The Appeal by Janice Hallett
A murder has occurred within a community theater group, someone has been convicted and two law students have been asked to review the evidence. The problem is that the truth must be extracted from hundreds of emails, messages and documents.
The Appeal does not use a conventional narrator. Readers encounter the same communications being examined by the students and must decide which characters are lying, which details matter and what may have been deliberately omitted.
Because the evidence is presented directly, readers can develop their own theories without having every clue interpreted for them. Minor inconsistencies take on new importance, and seemingly casual emails can completely change how a character’s motives are understood.
It is an especially effective puzzle novel because its unusual format is essential to the mystery rather than a decorative gimmick.
Best for: Readers who enjoy epistolary novels, unreliable witnesses and hidden clues.
10. The Twyford Code by Janice Hallett
In The Twyford Code, an ex-convict named Steven Smith becomes obsessed with discovering what happened to his former teacher, who disappeared decades earlier after finding what she believed was a secret code inside a children’s book.
The story is presented through transcriptions of audio recordings recovered from Steven’s phone. Errors in the transcription, strange phrases and apparent inconsistencies may contain clues or may send readers in the wrong direction.
The deeper Steven investigates, the more the mystery expands into a literary scavenger hunt involving coded messages, World War II and secrets buried in the past. Solving it requires attention to language and a willingness to question the accuracy of everything on the page.
This is one of the most intricate choices on the list and an ideal follow-up to The Appeal for readers who want an even more elaborate puzzle.
Best for: Word-puzzle enthusiasts who enjoy codes, acrostics and deceptive narration.
11. Murder in the Family by Cara Hunter
Nearly two decades after Luke Ryder was found murdered in the garden of his family’s London home, a true-crime television series reopens the cold case.
The entire novel is presented through episode transcripts, newspaper articles, photographs, emails, maps, text messages and production notes. A panel of experts analyzes the evidence, but new revelations also raise questions about the investigators themselves.
The format lets readers examine much of the same material as the television team. Instead of receiving the story through one detective’s perspective, you must compare competing theories and decide which information can be trusted.
Anyone who enjoys true-crime documentaries or podcasts should find the structure immediately familiar. Cara Hunter’s novel uses that familiarity to conceal clues among the arguments, interviews and behind-the-scenes drama.
Best for: True-crime fans who enjoy cold cases and mixed-media storytelling.
12. The Tokyo Zodiac Murders by Soji Shimada
For readers who want a traditional novel with a genuinely difficult, fair-play puzzle, The Tokyo Zodiac Murders is essential.
An eccentric artist leaves behind a plan to murder several women and use parts of their bodies to create a supposedly perfect woman. Soon afterward, the artist is found dead inside a locked room. When the other murders apparently follow his plan, the case becomes one of Japan’s most baffling unsolved crimes.
Decades later, an astrologer and his friend attempt to discover what really happened. Before the final explanation, the book pauses to challenge the reader directly, stating that the necessary clues have already been provided.
The crime is elaborate, strange and carefully constructed. It is an excellent example of the Japanese honkaku tradition, which emphasizes logical, fair-play mysteries that readers can theoretically solve before the detective.
Best for: Experienced whodunit readers who want an ingenious impossible crime.
Which Murder-Mystery Puzzle Book Should You Read First?
Start with Murdle: Volume 1 if you want short logic puzzles that can be completed in a single sitting. Choose Can You Solve the Murder? or You Are the Detective if you want to control an investigation and physically examine the evidence.
Readers who prefer full-length novels should begin with The Appeal or Murder in the Family. Both offer compelling stories while presenting the evidence through unconventional documents.
If you want the hardest possible challenge, try Cain’s Jawbone. Just do not expect to solve it over a quiet weekend.
For a traditional whodunit that still gives readers a fair chance to identify the culprit, The Tokyo Zodiac Murders is the strongest selection on this list.
Frequently Asked Questions
What is a murder-mystery puzzle book?
A murder-mystery puzzle book asks the reader to participate in solving a fictional crime. Depending on the book, that may involve completing logic grids, deciphering codes, examining evidence, choosing investigative paths or identifying contradictions in witness statements.
Are murder-mystery puzzle books different from mystery novels?
Some are activity books containing individual cases, while others are full-length novels constructed as solvable puzzles. Books such as Murdle prioritize logic exercises. Novels such as The Appeal and The Tokyo Zodiac Murders provide a complete story but still encourage readers to solve the central crime before the final revelation.
What is the best murder-mystery puzzle book for beginners?
Murdle: Volume 1 is the most accessible starting point because its earliest cases introduce the deduction-grid format gradually. You Are the Detective is another approachable option for readers who prefer visual evidence and one larger case.
What is the hardest murder-mystery puzzle book?
Cain’s Jawbone is widely considered one of the hardest. Readers must correctly order 100 shuffled pages and identify multiple murderers and victims using literary references, wordplay and hidden connections.
Conclusion
Murder-mystery puzzle books offer something that ordinary thrillers cannot: the opportunity to become part of the investigation.
The strongest books in the genre do not merely conceal the killer until the final chapter. They give readers access to the evidence, establish the rules and invite them to reach a solution independently. That makes the eventual revelation even more satisfying, especially when you correctly identify the murderer.
From the approachable logic grids of Murdle to the almost impossible literary challenge of Cain’s Jawbone, these 12 books provide plenty of cases for adult armchair detectives to solve.
