Rain hammered the empty pier. Detective Mara Voss arrived late. The ferry horn moaned twice. A body blocked the boathouse. Yellow tape snapped in wind. Someone had stolen his shoes. His wallet held no name. Only salt filled his pockets. Mara knelt beside the corpse. The tide erased every footprint. A lantern watched from offshore. Then its light went out.
