The House of Secrets was revived in 1969 after a 3 year absence. 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 House of Mystery. Swamp Thing first appeared in House of Secrets #92 (July 1971) in a stand-alone horror story set in the early 20th century written by Len Wein and drawn by Bernie Wrightson. The woman appearing on the cover of this issue was modeled after future comics writer Louise Simonson.
This revival, sporting many covers by Neal Adams, Bernie Wrightson, and Michael Kaluta, ran through issue #154 (Nov. 1978), with three months passing between #140 (April 1976) and #141 (July 1976). It was then ‘merged’ into The Unexpected with issue #189, through issue #199. The series was 68 ad-free pages, allowing all three portions to be full-length issues.
The House of Secrets also came to be the name of the actual edifice in which Abel lives. Writer Mike Friedrich and artist Jerry Grandenetti introduced the house and explained its origins. The Sandman series revealed it exists both in the real world of the DC Universe and in the Dreaming, as a repository for secrets of all kinds.
