In "Hostage of Dimension X," a scientist plucked from Earth finds himself trapped in a dying alternate realm, where his knowledge may be the key to saving their collapsing universe—or unleashing their invasion upon our own. With moody, otherworldly art by Ruben Moreira, this eerie 1962 tale from House of Mystery blends cosmic dread and moral tension. The cover, by Dick Dillin and Sheldon Moldoff, captures the moment of peril with stark, shadowed intensity.
