Crypt of Shadows #7

In "The Haunting of Bluebeard!" from Crypt of Shadows #7 (1973), a sinister innkeeper known only as Bluebeard preys on his guests—until a thief’s accidental possession of a bottle of Nitro changes everything. When Bluebeard tries to discard the bottle, he doesn’t realize the explosion has transformed him into one of the very spirits he once trapped. The story, written by an unknown author and illustrated by an unknown artist, turns his own cruelty against him in a chilling twist of fate.
