Marvel Masterworks: Atlas Era Tales of Suspense #2

Synopsis

A scientist moves into Dr. Frankenstein's castle to set up his experimental growth ray. When he trains it upon an amoeba, the frightened villagers burst in, and seeing the equipment, think he is going to bring ruin down upon them and hustle him off to the town jail. With no one to shut off the growth machine, the amoeba grows to huge size and smashes out of the castle to menace the village. The scientist escapes his jail cell and uses his labcoat soaked with sugar to lure Sporr into a quicksand pit.
