Cain's Jawbone is a murder mystery originally published in 1934 with the pages scrambled and out of sequence. In order to discover the murderers and their victims the reader must first solve the puzzle of the page order then solve the puzzle of whodunit to whom. Cain's Jawbone was written by Edward Powys Mathers using the pen-name Torquemada and was originally published by Victor Gollancz Ltd. It is now in the public domain. As a print-on-demand edition it will forever remain available for you to admire and solve, or to thwart and frustrate you. This edition, which is more or less a facsimile of the original, is provided here for your interest and critical appraisal. A facsimile of the original introduction as well as a facsimile of the original contest description are included in this book. Note, however, there is no longer a contest and there are no prizes.
