Lights Out was an extremely popular American old-time radio program, an early example of a network series devoted mostly to horror and the supernatural, predating Suspense and Inner Sanctum. Versions of Lights Out aired on different networks, at various times, from January 1934 to the summer of 1947 and the series eventually made the transition to television. In 1946, NBC Television brought Lights Out to TV in a series of four specials, broadcast live and produced by Fred Coe, who also contributed three of the scripts. NBC asked Cooper to write the script for the premiere, "First Person Singular", which is told entirely from the point of view of an unseen murderer who kills his obnoxious wife and winds up being executed. Variety gave this first episode a rave review ("undoubtedly one of the best dramatic shows yet seen on a television screen"), but Lights Out did not become a regular NBC-TV series until 1949..
