When a young hooligan is accused of murdering a prominent resident on the Isle of Man, Inspector Littlejohn must uncover the truth in this classic mystery.

In a small town on the Isle of Man, an elderly gentleman is found violently stabbed in an alley, andhis wallet missing. All fingers point to a suspicious Teddy-Boy visiting from Liverpool. The victim was a well-known member of a distinguished family, and his relatives are eager to see justice served. To avoid an unwarranted arrest, the Manx police call in Inspector Littlejohn of Scotland Yard to investigate.

While the young man maintains his innocence, Littlejohn's investigations lead him to the Bishop's Arm pub. There he meets some of the island's most dubious characters and begins to uncover surprising secrets about one of the island's most respected individuals.
