Plot summary
On an anonymous tipoff, Goren and Eames have the body of wealthy James Whitney exhumed and determine that he did not die of natural causes but was poisoned. They discover his attention-seeking widow, Marion Whitney ( Claire Bloom ), has begun hosting charity events with event manager, Harvey Gruenwald ( Casey Siemaszko ) who is having financial difficulties. When Harvey's mother, Esther Gruenwald ( Rebecca Schull ) is found murdered in her apartment, they investigate Harvey and find he is deeply indebted to his silent partner and loan shark, Nick Weaver ( Sal Richards ). Further investigation indicates that Harvey killed James Whitney and that Marion Whitney arranged for Nick Weaver to have Harvey's mother killed to prevent her exposing her son's activities.
