At midnight, Detective Vale arrived at Blackthorn Manor, where the host lay dead beneath a chandelier dripping rainwater indoors. Every guest claimed innocence, yet each wore a silver key matching the lock on the room where he died. Vale noticed the windows stood sealed, the fireplace cold, and muddy footprints stopped abruptly beside an untouched glass of wine. Then the grandfather clock struck thirteen, and somewhere upstairs, a woman screamed the dead man's name into the darkness beyond.
