The rain hammered the windows of Blackwood Manor as Detective Clara Voss stared at the lifeless body on library floor. Lord Edmund lay twisted beside overturned armchair, crimson blood pooling beneath silver candlestick that had apparently crushed his skull brutally. Outside thunder rolled across darkened hills while inside five nervous guests exchanged glances, each silently wondering who among them lied. Clara knelt carefully, noticed muddy footprints leading toward secret passage, then realized victim clutched torn photograph in his cold hand. She opened his stiff fingers, gasped at familiar face circled in red ink, and whispered that killer was still inside. Suddenly lights died, someone screamed upstairs, a door slammed violently, and Clara drew her revolver knowing night had only begun.
