A literary puzzle that went unsolved for almost 100 years was figured out again.

Cain’s Jawbone was published in 1934 and envisioned by Edward Powys Mathers. The puzzle invited readers to reorder its 100 pages, with over 32 million possible combinations, and solve the murders within. Two readers solved the mystery in the 30s. However, the solution was lost for decades until recently. Last year the Laurence Stern Trust re-solved it, reviving the original competition. It was eventually won by British author John Finnemore, who cracked the code while self-isolating.
