The lighthouse bell rang twice before the body finally surfaced. Detective Mara Venn arrived with cold rain soaking her coat. On the sand, a dead woman stared at the moon. Her silver dress was dry, and bruises ringed her throat. Mara recognized the senator's young wife from last winter's newspapers. Yet Evelyn Cross had been buried just three days earlier. Behind Mara, a man coughed beside the locked green boathouse. She turned, finding only a brass lantern swinging in darkness. Inside the lantern, a single folded note was slowly smoldering. Mara seized the note before flames consumed its penciled message. It read, “You buried the wrong woman, Detective Mara Venn.” Within the corpse's fist lay a key bearing Mara's initials. Behind her, the old boathouse door clicked open from within.
