“HEART OF A VAMPIRE.” Alfred and Bruce are miles outside of town when their car mysteriously overheats. They go to a nearby boarded-up house to find some water for the radiator. Inside they discover a coffin and a very old sunlamp, which Bruce accidentally breaks. They split up to search when vampire Gustav Decobra exits the coffin and attacks Bruce, who changes to Batman. Batman puts a wooden beam through Gustav’s chest, but finds that his heart is not where it should be.
