What happens
Mr. Pender, a respectable London commuter, shares a train compartment with a stranger who claims to know a method of committing murder that could never be detected. The stranger, Smith, boasts of a poison that works through a hot bath, and Pender later finds the claim unsettling when a neighbour is found dead in his bath. Pender begins to suspect that the same method is being used around him. The episode is part of the Suspense series, broadcast on CBS, and stars Charles Laughton as Pender.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
