There were several comic books in the early Sixties that included tales of both magic and science fiction, but the two genres were rarely combined into an individual story. An exception was the DC title House of Secrets which between 1959 and 1965 featured a magician named Mark Merlin. Mark Merlin was a supernatural sleuth (think Doctor Strange, except more sensibly dressed) who lived in a mansion he inherited from his stage magician uncle. The mansion was located on Mystery Hill and contained a vast collection of occult books and artifacts. Defying all expectations from an expert in the supernatural, Merlin would use these tools to battle extraterrestrial threats to Earth far more often than he used them to thwart villains with an occult bent. Along for the ride was Merlin’s beautiful blond secretary and girlfriend, Elsa Magusson.
Mark Merlin was created and drawn by Mort Meskin, however, as with My Greatest Adventure, the covers were all done by the prolific Dick Dillin. Here is the 1961 cover gallery for House of Secrets:
