What happens
Naval vessels suffer a series of explosions and damage, and the navy traces every incident to the Sagg Island shipyard. Lamont Cranston, using his power to become invisible and read minds, suspects a man among the yard's workers and sets up a radio post at a nearby hotel. He follows a shady worker named Steve Buckler to a bar, where Buckler's meetings draw him into a dangerous scheme. The Shadow's pursuit of the saboteur continues through the night as the threat to the fleet grows. This episode of The Mercury Theatre on the Air aired on 1938-01-16.

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.
