Terence Rattigan liked to do plays based on actual crimes. He is best known for THE WINSLOW BOY, based on the 1911 Archer-Shee Case involving the social ruin of a naval cadet and his family when the cadet is accused of stealing postal money orders from his fellow cadets. It was twice filmed (both times quite well). CAUSE CELEBRE is based on the 1935 Alma Rattenbury - George Stonor murder case. Alma was a somewhat talented woman (she composed popular songs) who married Francis Rattenbury, an architect (his various public and private buildings in Vancouver are still part of the city's skyline). Francis was older than Alma, and she began an affair with Stonor, a handyman they hired. One night Stonor shot Francis, and he died in a couple of days. Stonor was arrested, and then so was Alma. It sort of resembles the Thompson-Bywater tragedy in 1922, but Alma was shown to have had nothing to do with the shooting. Stonor, however, was found guilty and condemned to death. Alma could not stand the loss of her young lover. She went down to a river near her home, and stabbed herself to death. Ironically, due to his age, Stonor's sentence was reduced to life imprisonment. Eventually he was released. However, in the 1980s (he was still alive) he was arrested on a morals charge. The play of course only deals with the events in 1935.
