For Sale: Luxury Condos, Corpse Included

Just a stone's throw from Judith McMonigle Flynn's thriving Hillside Manor, workmen are busy renovating the elegantly decrepit Alhambra Arms into pricey condominiums. But concerned contractor George Guthrie fears that well-heeled potential buyers may blanch when they learn about the four-decades-dead body that was stashed behind the crumbling walls of the moldy manse. And ever-inquisitive Judith's discovery of some much more recent remains on the premises threatens to se property values through the floorboards--and Guthrie through the roof! Both her professional detective husband Joe and her partner-in-crime solving cousin Renie think Judith is bonkers to suspect that the two killings are connected. Nevertheless, Judith's ready to build a strong case to that effect -- unless some homicidal someone decides to deconstruct her first!
