Heavy rain tapped violently against the shattered window of the study while Lord Blackwood lay dead upon the Persian rug. Detective Inspector Vance crouched beside the wealthy aristocrat, noting the antique silver dagger protruding from his cold, lifeless, bleeding chest. A single crimson footprint led away from the gruesome crime scene toward the locked mahogany doors of the grand library. The grandfather clock in the shadowy corner had stopped ticking at precisely midnight, marking the exact moment of his demise. Downstairs, five nervous guests sipped their brandy in silence, each hiding a dark motive for wanting the cruel host dead. Vance picked up a burned scrap of paper from the fireplace, realizing the killer was still inside this isolated mansion.
