From the Publisher:
As LAPD detective Kate Delafield investigates the Thanksgiving Day strychnine poisoning of retired movie director Owen Sinclair, she discovers that he turned over names to the House Un-American Activities Committee in the 1950s and destroyed countless careers. But which of his charmingly eccentric neighbors, most of whom have worked in Hollywood since the 1940s, might be responsible for what now appears to be a revenge killing?
