Detective Mara Voss arrived at Blackwood Manor just after midnight. Rain hammered the stained glass windows while thunder rolled outside. The body of Lord Edmund Crane lay in the library. His silver letter opener protruded from his chest quite deeply. Six guests waited in the parlor, pale and silent. Each one had motive, opportunity, and a tangled alibi. Mara knelt beside the body and studied the scene. A torn letter rested beneath the fallen crystal chandelier. The fire had died hours ago, leaving only ash. Somewhere upstairs, a clock struck twelve with deliberate, mocking slowness. She stood slowly, sensing that every guest was watching. One of them had killed a man tonight.
