A series of unusual rainstorms have resulted in several deaths. Sent to investigate this phenomenon, Steed and Emma come across an eccentric German scientist named -- believe it or not -- Dr. Sturm (Albert Levien). Before they are able to neutralize Sturm's rainmaking machine, Steed is nearly drowned, and Emma faces a slow and nasty death in a wine press. Written by Colin Finbow, "A Surfeit of Rain" was originally telecast in England on November 26, 1965; curiously, it was never shown on American network television, though it was later included in the series' syndicated package.
