Edgar Allan Poe's classic story "The Pit and the Pendulum" (1842) was adapted for Suspense by John Dickson Carr. Poe's story wasn't long enough to fill a half-hour show, so it was expanded with the addition of a court scene and a running dialogue that takes place in the mind of the prisoner. The result was an unusual combination of Poe, Carr, and Suspense that was presented four times between 1943 and 1959. John Dickson Carr was considered a master of the "locked room mystery," and he wrote many of Suspense's early episodes.
Suspense first presented this story with Henry Hull in the role of the prisoner. William Spier produced, John Dietz directed, and Bernard Herrmann composed/conducted the music. This episode aired on January 12, 1943.
