Often compared to a long-form riddle or literary cryptic crossword, this puzzle book was first released in 1930.

The book has been so highly thought of for so long that a Crowdfunding publisher managed to re-release the book as a new standalone edition in 2019.

Once part of the Torquemada Puzzle Book, Cain’s Jawbone is a 100-page puzzle book that was designed to put the reader’s skills to the test.

What makes this puzzle so hard is that all of the pages are in the wrong order.

It is down to the reader to solve the puzzle. To do so, readers must determine the correct page order and the names of the victims and murderers in the story.

The puzzle book is so hard to solve that the answer has never been made public.

If you liked Cain’s Jawbone, you’ll also enjoy Could You Survive Midsomer, The Cypher Files, The Paper Labyrinth, Who Killed The Robins Family, and Montague Island Mysteries. These addictive puzzle books will drive you crazy!

Themes In Cain’s Jawbone

Reader Interaction

Easily the most common and most important theme in Cain’s Jawbone is reader interaction.

The whole idea of this book is to engage the reader in an addictive puzzle that seems almost impossible to solve.

Whilst the murder mystery puzzle genre is packed with entertaining and interesting books, Edward Mathers’ Cain’s Jawbone is widely regarded as the best.

The reader will have to work hard to crack the puzzle. If they can, they should be able to work out who the victims and murderers in the story are.


In terms of themes found in the story, this book centers around murder.

It is down to the reader to find the people responsible for six murders. As a result, this book features crime scenes, grizzly murders, murderers, and violence.

Only by unscrambling the pages will the reader be able to find the murderers.


As you would expect from an addictive murder mystery puzzle book, one of the most common themes throughout is mystery.

Mathers has brilliantly put together a story that can only be solved using great skill and intelligence.

The book is designed to keep the reader guessing right until the very end.

Having said that, there is no guessing in Cain’s Jawbone. It takes great patience and skill to crack the case.


Finally, patience is also a key theme presented in this book. The mystery wasn’t designed to be solved straight away.

Instead, Mathers wants the readers to work hard for the answers.

In fact, it could be argued that the puzzle is impossible to solve without a great deal of patience.
