Yellow Iris - Play

A distressed phone call from a mystery woman brings Hercule Poirot to the hotel Jardin des Cygnes, where a man commemorates the four-year anniversary of his wife’s sudden death – a death under very suspicious circumstances that Poirot himself witnessed. Gathered is everyone present on that fateful night and now Poirot must find a killer in the midst, before they strike again.

Yellow Iris marked Hercule Poirot's debut appearance on radio and Christie later used the central idea and setting for her 1945 full-length novel Sparkling Cyanide.
