The Queensville Heritage Society is restoring the once-grand Dumpe Manor. While Dumpe relatives and society members use the occasion to dust off old grudges, Jaymie Leighton prefers to adorn the kitchen with authentic Depression Era furnishings. A collection of vintage wooden mallets found in the house is a perfect addition to her display, but one also offers a late-night intruder the perfect weapon to knock Jaymie unconscious before escaping. Though the attack has everyone on edge, nothing is missing from the house. Perhaps it was merely a vagrant who thought the place was still abandoned. But when Dumpe Manor's resident historian is murdered with a mallet from the same collection, it's time for Jaymie to turn up the heat on the investigation before someone else becomes history.
