Innkeeper Judith McMonigle Flynn has the post-holiday blues from the usual lack of guests at Hillside Manor. But she's up for house-sitting at her aunt and uncle's retirement home on Whoopee Island. With Cousin Renie in tow, the duo expect a quiet time at the beach until they find a dead body soon after their arrival. When what they assume is a fatal heart attack turns out to be death by stabbing, Judith reluctantly begins sleuthing-if only to prove that she and Renie aren't the prime suspects. The victim didn't have an enemy in the world-except for whoever killed him. Digging for more than clams, the cousins discover that retirement isn't all it's cracked up to be, at least among the eclectic, eccentric residents of Obsession Shores.
