Cain's Jawbone is a 1934 literary puzzle by Edward Powys Mathers, republished by Unbound. It is a murder mystery printed as 100 loose-leaf pages that must be reordered to reveal six victims and their killer. Only a handful of readers have solved it since the original contest. It suits puzzle fans who want a hard, hands-on challenge rather than a straight read. The Unbound edition is a compact paperback with detachable pages, so it can be shuffled and rearranged.
