Adaptation of the short-story "The Tell-Tale Heart" by Edgar Allan Poe.
Adaptation of the short-story "From Fanaticism, Or for Reward" by Harry Harrison from the magazine Analog (Mar 1969). Originally done in 1971 and had been intended to appear as a 10 page story for the aborted Science Fiction Odyssey #1. It was expanded to 11 pages by inserting a pin-up page taken from what was intended to be the frontispiece. The original author, Harry Harrison, was one of the original EC horror artists.
