Mystery in Space #100

Issue #100 of DC's long-running sci-fi anthology reaches a milestone with a cover by Dick Dillin and Sheldon Moldoff that crackles with paranoid tension. The scene shows two humans caught in a desperate confrontation with orange-skinned, insectoid Jovian aliens — one human pleading "I'm not a Jovian!" while another grimly confesses "But I am!" as a ray gun flashes nearby, teasing the double-identity intrigue of the featured story, "Secret of the Double Agent." Inside, writer Jerry Siegel and artist/inker Lee Elias deliver "The Death of Alanna," making this 1965 issue a satisfying blend of Cold War-flavored espionage and imaginative outer-space adventure.
