Rain hammered the old lighthouse windows without relentless mercy tonight. Detective Miller found the keeper sprawled across cold stone floor. Blood pooled beneath his head, steaming faintly despite bitter chill. The logbook lay open, its final entry unfinished quite abruptly. Outside, wind howled through cliffs, masking footsteps long already gone. Miller noticed the second coffee mug still very warm nearby.
