**It's a picture-perfect Vineyard summer, and ex-Boston cop J.**W. Jackson finds time for lazy afternoons at the beach with his wife, Zee, and the kids. Nothing could be better, but of course not everything is peaceful, even on this idyllic island.

But trouble is waiting for J.W. in the sand trap at the fourth hole—the sand trap with the human hand protruding from below. With circumstantial evidence pointing to J.W., he must act fast, peeling back layers of deceit surrounding old Vineyard families in his search for a killer.
