This curiously little-known British mystery stars Tom Conway as an American FBI agent. Conway is sent to England to investigate the death of a model. It just might be that enemy agents are involved, and our hero wants to find out as much as possible before putting his own life on the line. The most familiar faces in the supporting cast belong to Delphi Lawrence, Eric Pohlmann and Richard Wattis. Three Stops to Murder is one of the earliest efforts of future "house of horror" Hammer Films.
