Postman Sam Nelms took a strange turn in his morning delivery when he found that the nearby cottage, Goodfellers, and Thomas' residents were all gone, leaving only half of his breakfast on the table. A few years ago, the son of the Thomas family died in the nearby Monks Barton Forest. It is believed that there was a ghost there, and Cyrus Levinu, the famous psychic, came to the forest to exorcise demons. The bodies of a known antique thief and the Thomas couple have been discovered, while Stanley Goodfellow has been found talking nonsense, clearly insane. An antique theft gang has been exposed, led by the next victim who made ghostly noises in the woods to scare people away from his crimes. Barnaby now knows who the killer is, but according to Cyrus's psychic ability, Stanley's living wife's position shows that it is possible to talk with the deceased.
