House of Mystery #128
In "Captives of the Robot Brain!", three shipwreck survivors on a mysterious island find unexpected aid from an intelligent robot that provides food and shelter—but refuses to let them depart. Drawn by Howard Purcell, whose distinct style brings the eerie isolation and mechanical precision of the island to life, this 1962 tale from House of Mystery blends early sci-fi suspense with classic mystery thrills. The cover, by Mort Meskin and George Roussos, captures the tension of the stranded castaways and their enigmatic caretaker in stark, atmospheric detail.
