A Vintage Murder Mystery With a Bizarre Twist

One of the world’s most fiendish literary puzzles is a murder mystery in which all the pages are out of order. Cain’s Jawbone was dreamed up by crossword inventor Edward Mathers. First published in 1934, it invites the reader to reorder the book’s 100 pages, which is no easy feat considering there are roughly 32 million combinations to solve the murder. The pages have been printed in an entirely haphazard and incorrect order, but the author assures readers that it’s quite possible for them to re-order the pages correctly and solve the murder. So far, only two readers have managed to solve the puzzle, both in the 1930s. The solution was then thought to be lost, but it was again discovered and reissued last year.
