A reclusive, haunted Dr. Frankenstein and his assistant are visited by a strange, persistent stranger in this haunting short story by R.L. Stine.

It's a dark and stormy night, and the new, unnamed assistant to the penniless Dr. Victor Frankenstein answers the front door's knock. There stands a stranger, who has managed to track down the elusive doctor and forces a wager: reanimate the man's dead brother or face exposure to the community at large. But who is gaming whom -- will the massive corpse actually be revived?
