Rain battered Blackthorn Manor's windows. Guests gathered beneath flickering chandeliers. Lord Harrow raised his glass. Someone screamed behind velvet curtains. The lights vanished without warning. A gunshot shattered nervous silence. Candles returned, revealing Harrow's corpse. Blood darkened his immaculate waistcoat. Detective Vale calmly locked doors. Nobody noticed the missing violin.
