Rain silvered the empty pier. Mara reached the lonely boathouse. The padlock hung open, broken. She pushed against the door. A lantern revealed the corpse. He sat facing the sea. His wrists bore violet thread. No blood stained the floor. Yet his shadow kept moving. Then every harbor bell rang. Mara turned toward the door. Someone whispered her childhood name.
