The series began in April–May 1975. Like its predecessor Secrets of Sinister House, Secrets of Haunted House was originally “hosted” by Cain, Abel, Eve, and Destiny who had moved over from Weird Mystery Tales. By issue #10 (Feb.–March 1978), Destiny was the only one of these who remained a regular. In issue #40 (Sept. 1981), Abel returned with no further mention of Destiny.
A Secrets of Haunted House Special was published in 1978 as part of the DC Special Series umbrella title. Secrets of Haunted House was a temporary victim of the “DC Implosion.” With issue #14 (Oct.–Nov. 1978), it was cancelled but revived a year later with issue #15 (Aug. 1979). The title continued until issue #46 (March 1982).
