Fog rolled through the harbor and swallowed the lamp light. Detective Ames arrived in a coat stiff from winter rain. Yellow tape fluttered like a wounded bird around the pier. A body lay face down, shoes still tied tight there. Blood pooled beneath a wrist, dark and almost black now. No neighbors saw anything, though someone had called the police. A child left sobbing on the quay clung to shoes. Detective Ames crouched, inspecting footprints leading toward the old warehouse. The warehouse door hung ajar, its darkness breathing slow secrets. He tasted metal on his tongue and remembered his past.
