Rain hammered the old lighthouse windows without any mercy tonight. Detective Mara Hale found the keeper lying cold downstairs motionless. A shattered lantern cast strange shadows across his still face. The logbook lay open, its final entry violently torn out. Mara noticed fresh muddy footprints leading toward the locked tower. Outside thunder roared while waves threatened the fragile rocky cliffs. Somewhere above, a heavy door creaked slowly shut with purpose.
