The rain hammered the manor windows as the candles flickered in dread and fear revealing a body on marble floor. Detective Vance knelt beside the corpse noting the silver key and a torn envelope lying nearby on the dark rug. No one screamed when the lights died yet the chandelier trembled over the gathered guests like a warning to all. Madame Lorraine read the teacup but her painted smile faltered at the dark red rim while thunder shook the house. The dead body lay with one hand pointing toward a portrait of a woman wearing his ring beneath the clock.
