Cain’s Jawbone

“Cain’s Jawbone, a 100-page-long murder mystery puzzle, was last cracked in 1935 when two puzzlers claimed £15 in winnings, just a year after it was originally published.

Now a British comedian has solved the literary puzzle for the first time in 85 years, after submitting the correct solution shortly before the closing of a new year-long competition.
