"Blueprint for Murder" written and illustrated by Jon Hastings. This is the story of how Master Gracey's first two guests, architects Mr. Davis and Mr. Coats (a reference to original Haunted Mansion designers Marc Davis and Claude Coats), were hired to build the house. But Master Gracey favored Mr. Davis' work more than Mr. Coats' work, causing Mr. Coats to lead Mr. Davis astray in the mansion then trapping him tightly in a casket. But Mr. Davis who was the only one who knew how to navigate the mansion caused Mr. Coats to get lost for eternity within the gloomy darkness of Gracey Manor. In the end Mr. Davis became the ghost trying to break out of the coffin in the conservatory and causing Mr. Coats to become the invisible ghost that carries a candelabra.
