By October 31st, 1948, The Mutual Broadcasting System’s flagship WOR in New York was approaching its twenty-seventh anniversary. It was argued that no station matched its signal coverage. WOR-Mutual was known for its cop shows, soap operas, and on Sundays, it’s mysteries.

At 4PM eastern time, House of Mystery signed on for General Foods. John Griggs was Roger Elliott, ghost hunter and scientist of the supernatural. The show was directed by Olga Druce, who guided the program along a fine line. Because House of Mystery was geared for children, it couldn’t be overtly gruesome or vulgar.
