S1·E30 Scar and Garter

A young, recently married woman hires Mike to find her husband, who disappeared after visiting his estranged mother at her Berkshire Mountains mansion. Mike's efforts to visit the man's mother meet resistance from the woman's secretary and groundskeeper, but he manages to confront her in the estate's garden. He discovers that the man's mother is a former Broadway star whose face was disfigured by a knife-wielding thug ten years earlier. When he finds the body of a young man in a shallow grave on the property, he becomes more determined than ever to have the bride meet her mother-in-law and learn the identity of the corpse buried on the grounds.
