During a holiday by the British seaside, Hornleigh and Bingham grow bored and turn their hand to investigating a local crime.

During a charity football match between Arsenal and touring amateur side Trojans, the Trojan's new star player collapses and dies. Inspector Slade of Scotland Yard is called in and declares it was murder. It takes all his ingenuity and another death before the motive is discovered and the killer revealed.
