With the holidays gone and Hillside Manor almost empty, Innkeeper Judith McMonigle Flynn has a bad case of the blues. A housesitting stint at her aunt and uncle's retirement home on Whoopee Island with cousin Renie seems like the ideal pick-me-up. But it isn t long before a dead body pops up in their vicinity. Not surprising in an area full of older folks - until they learn it wasn t a bad ticker that did in the victim, but a very sharp knife. With clouds of suspicion hovering over her and Renie, Judith reluctantly begins sleuthing. The victim reputedly didn t have an enemy in the world - except for the killer. Digging for clams and answers, the cousins discover that retirement can be deadly - at least among the eclectic, eccentric residents of Obsession Shores.
