Information for Ghost Stories at Sheffield Theatres, Sheffield (Play). Three men gather, each with an uncanny tale to tell: their chilling stories will bleed off the stage and into your dreams. When Professor Goodman, arch-sceptic out to debunk the paranormal, embarks on an investigation of three apparent hauntings - as recounted by a night-watchman, a teenage boy, and a businessman awaiting his first child - Goodman finds himself at the outer limits of rationality, and fast running out of explanations.
