Thick fog choked the pier. Cold rain washed the wood. One lone flashlight flickered twice. The dead man lay still. Fresh blood stained his collar. A silver watch ticked softly. Footsteps echoed in the dark. Someone ran toward the water. A heavy splash followed soon. Then, silence claimed the night.
