The Tuesday Night Club is the name for a varied group of guests who challenge each other to solve recent, and not so recent, crimes. It begins one evening when the group gathers at Miss Marple’s house and the conversation turns to unsolved crimes. Over the weeks, we learn about the case of the dripping bloodstains, the thief who committed his crime twice over, the message from the death-bed of a poisoned man who talked of a 'heap of fish’, the strange case of the missing will, and a spiritualist who warned that ‘Blue Geraniums’ meant death.

Pit your wits against the powers of deduction of the ‘Tuesday Night Club’. But don't forget that Miss Marple is present. Sometime later, many of the same people are present at a dinner given by Colonel and Dolly Bantry. Another set of six problems. Even later there's a thirteenth. Can you match Miss Marple's performance?
