Rain battered Blackthorn Manor windows. Twelve guests watched midnight approach. Sir Alistair Vale raised champagne. His smile concealed something colder. Nobody noticed the locked study. Nobody except Clara Finch, perhaps. She studied muddy footprints nearby. Their toes pointed toward nowhere. Then darkness swallowed every chandelier. A scream split the storm. Lights returned; Vale lay motionless. Blood darkened his white collar. His silver key was missing. Clara knelt beside the body. Outside, thunder answered her questions. Every guest denied hearing footsteps. Yet someone wore wet shoes. Clara closed the study door. No murderer would leave tonight.
