Diana Powell, in 100 American Crime Writers, wrote:
Cabin B-13 is the harrowing tale of a new bride who boards an ocean liner for her honeymoon only to find out the groom has disappeared and that the ship's crew doubt his existence and her sanity. Her fear over her groom's whereabouts is heightened by a threat to her inherited wealth and the stress of not being believed.
Cabin B-13 was first broadcast on the American radio program Suspense on March 16, 1943, with Ralph Bellamy  starring. It was broadcast again on Suspense on November 9, 1943, this time co-starring Margo and Philip Dorn. The trade publication Radio Daily reported in its December 26, 1948, issue that the play would "have its third airing over CBS Saturday, December 27" — as a standalone program rather than being broadcast as an episode of Suspense. Additionally, the article noted, "Screen executives on the West Coast will hear Cabin B-13 in a special rebroadcast over KNX, Hollywood, Saturday, January 3, 4:00-4:30 p.m. in order to weigh its screen possibilities."
On September 11, 1943, Cabin B-13 was used for the premiere of the  British Broadcasting Corporation program Appointment with Fear. Richard J. Hand, in his book Listen in terror: British horror radio from the advent of broadcasting to the digital age, wrote, "Carr deliberately chose Cabin B-13 [for the first episode] as he felt it was his best Suspense play and would be an effective opening for this British series in the American style."
