The rain hammered Inspector Hale's old coat relentlessly that night. Yellow tape fluttered around the deserted dark harbor warehouse entrance. Inside, a single lantern illuminated the victim's pale still face. Hale noticed strangely no footprints beyond the chalk outline nearby. Only a silver pocket watch ticked beside his cold hand. Its hands had stopped precisely at midnight, Hale silently observed.
