Rain battered Blackthorn Manor's windows. Guests gathered beneath the crystal chandelier. Colonel Vale poured another brandy quietly. Then the library lights vanished. A scream shattered everyone’s careful composure. Lightning revealed the body downstairs. Lady Morwen clutched her pearl necklace. Blood darkened the polished marble floor. The victim held a silver key. Inspector Hale arrived before midnight struck.
