Menace #10

A scientist invents a cobalt bomb that results in monstrous mutations in a few individuals present at the test site. He hunts them down and shoots them, but when he awakens from the night's work and looks in the bathroom mirror, he sees a monstrous visage glaring back at him. He thinks that he must have been affected as well and uses the gun on himself. The shot wakes his son and wife, but the mother tells her boy it was probably a car backfiring and to go back to sleep. The boy asks his mother how dad will take the joke he played taping a monster picture onto his bathroom mirror.
