Spencer Murphy is a national treasure. A famous Vietnam War correspondent who escaped captivity in Southeast Asia, he made a fortune off of his books and television appearances. But Spence is growing forgetful with age; he’s started to wander and even fails to come home one night. When a body is discovered at Step Above, the sprawling Murphy house near Steps Beach, Nantucket police detective Meredith Folger is called in to investigate.
The timing couldn’t be worse: It’s the Fourth of July, and tourists are arriving in droves to celebrate on Nantucket’s beaches, so the police force is spread thin. On top of that Merry is planning her wedding to cranberry farmer Peter Mason, and her new boss, an ex-Chicago police chief with an aggressive management strategy, seems to be trying to force her to quit. Merry can’t conclude the Murphy investigation quickly enough for him. As she grapples with a family of unreliable storytellers—some incapable of recalling the past, and others determined that it never be known—she suspects that the truth may be forever out of reach, trapped in the failing brain of a man whose whole life may be a lie.
