Crimson Shore (Agent Pendergast #15)

Special Agent Pendergast takes on a private case in Exmouth, Massachusetts—a quaint village on the coast north of Salem—to investigate the theft of a valuable wine collection. He travels to the seaside town with his ward, Constance Greene, where they quickly discover something far more sinister: a bricked-up niche in the wine cellar that holds the remains of a man, tortured and then entombed alive 150 years ago. But why?

The puzzle is compounded when they discover a freshly murdered body—covered with mysterious symbols—in the salt marshes behind Exmouth…the place where, legend has it, the real witches of Salem took refuge after fleeing the 1692 witch hunts.
