Frankenstein and the Zombies

Here are two stories: a novelette, Frankenstein and the Zombies, and a short story, The Walking Corpse. The monster falls into the hands of a voodoo priest, who plots to create an army of zombies to conquer the world. He plans to revive and use the monster with voodoo sorcery in his plot. A young man and his girlfriend discover the plot, and are in grave danger.
In "The Walking Corpse," three young boys seek excitement in the dungeons of an old abandoned prison, where it is rumored that zombies lurk, waiting for prey.
