VAULT OF EVIL (1973) #15

Reprint of the 4th story from Marvel Tales #96 Satan sends an emissary to a horror story publisher so that he will read the scroll of suffering and be transported to Hell as a living man. Satan wants his soul because the stories he publishes turn people away from evil, but he cannot collect it until he is dead, so he puts the curse of Satan upon the publisher to kill the first person he sees (as then he will be executed for the crime), and sends him back. But Satan forgets that the first person the publisher sees upon his return to Earth will be the emissary, and when the publisher strangles him, the body disappears so there is no criminal prosecution.
