This story was originally done on the CBS radio series "Suspense" as "Cabin B-13" on March 16, 1943, starring Ralph Bellamy. It was so popular that the story was repeated on November 9, 1943 with a different cast, including Margo as the wife, Philip Dorn as the doctor, William Johnstone as the husband and Dennis Hoey as the ship's Captain. CBS later used the title "Cabin B-13" for a 1948 radio anthology series written by John Dickson Carr, the author of the original "Suspense" radio play. CBS presented the story once again on the TV version of 'Suspense" on March 29, 1949 with Charles Korvin & Eleanor Lynn. 1958 brought yet another version to TV as an episode of the 'Climax!" series that aired June 26th. It also turned up on the Canadian Broadcasting Corp (CBC) series "The Unforeseen" on April 22, 1959. The cable network USA aired a remake, titled "Treacherous Crossing," starring Lindsay Wagner, on April 8, 1992.
