Terror by Night

Holmes (Basil Rathbone) is on board to protect a valuable diamond from the clutches of master criminal Colonel Sebastian Moran. The trouble is, Moran is a master of disguise, and could be just about any one of the other passengers. Murder and mayhem plague the train excursion before Holmes can successfully complete his mention. Poor old Dr. Watson (Nigel Bruce) is a bit denser than usual here, though his ingenuousness is cleverly woven into the script.
