The House of Secrets is the name of several mystery, fantasy, and horror comics anthologies published by DC Comics. It is notable for being the title that introduced the character the Swamp Thing. It had a companion series titled The House of Mystery. Publication history First series The original Silver Age series ran 80 issues, from November/December 1956 to September/October 1966. In addition to short "one-off" stories, several issues featured the adventures of modern-dress sorcerer Mark Merlin, who first appeared in issue #23 (August 1959). The dual-personality supervillain Eclipso ("Hero and Villain in One Man!") was created by Bob Haney and Lee Elias and was introduced in issue #61 (August 1963) and continued to the series' end. Prince Ra-Man the Mind-Master bowed in #73 (July–August 1965) and was a Doctor Strange-style "replacement" for Mark Merlin. Prince Ra-Man twice battled Eclipso. The "Prince Ra-Man" feature ended in House of Secrets #80 (September–October 1966), the final issue of the series. Other, lesser continuing features included "Peter Puptent, Explorer"; "Dolly and the Professor"; "Doctor Rocket"; and "Moolah the Mystic". Revival (second run) The series was revived three years later with a definite article as The House of Secrets, beginning with issue #81 (Aug.–Sept. 1969). Now its horror and suspense tales were introduced by a host named Abel, who would also host the satirical comic Plop!. His brother, Cain, hosted The House of Mystery. The title had an early breakthrough for the mainstream part of the medium: issue #83 had a story, "The Stuff that Dreams are Made of", written by Marv Wolfman. As part of the framing story, Abel introduces the story by telling a tale told to him by a "wandering Wolfman". Upon examination, the censor bureau, the Comics Code Authority refused to give the issue its seal of approval since it mentions a wolfman, which was specifically forbidden along with other classic monsters. The series' editor, Gerry Conway explained that the writer's actual surname was Wolfman, and the CCA conceded on the condition that the distinction be made obvious with an explicit writer's credit in the story. That directive was complied with and suddenly the editorship of DC was inundated with complaints from other writers because of Wolfman's special consideration of a printed credit. In response, the editorship made writers credits standard practice for future publications. The Swamp Thing first appeared in The House of Secrets #92 (July 1971) in a
