Fog smothered the harbor lights. Inspector Hale arrived before dawn. A scream had ended suddenly. Dockworkers stood silent shivering nearby. Blood darkened the slick planks. The victim lay facedown stiff. A silver locket gleamed open. Inside a child's portrait watched. Hale noted footprints leading inland. One print dragged oddly heavy. Rain began erasing their edges. Someone whispered 'He deserved it'.
