The gripping new crime novel in the Peter Decker and Rina Lazarus series from New York Times bestselling author Faye Kellerman. LAPD lieutenant Peter Decker is sent to investigate complaints of a putrid smell coming from an apartment rented by Hobart Penny, an eccentric aging engineer. A recluse for the last 25 years, it isn't surprising that the troubled genius might have died without anyone knowing. However, as Decker steps inside, it's clear that this is a murder scene. A thorough search reveals further evidence of a disturbed, depraved man: human body parts. So who was Hobart Penny?
