A sequel to Cain’s Jawbone, a literary puzzle that has only been solved by a handful of people in the almost 90 years since it was published, is to be released.
Cain’s Jawbone is a murder mystery in which six people die, and was written by Edward Powys Mathers, known as Torquemada, who was the Observer’s cryptic crossword compiler at the time of the book’s release in 1934.
