The rain hammered hard against the tall glass windows of old Blackwood Manor as Detective Sarah Chen finally stepped inside. Lord Edmund's pale body lay sprawled across the Persian rug, his cold lifeless eyes staring at the ornate ceiling above. A silver letter opener protruded from his chest, and a glass of expensive brandy sat untouched on his mahogany desk. The elderly housekeeper had discovered him at dawn, screaming loudly enough to wake every single sleeping servant within the house. Now the entire study buzzed with quiet activity as uniformed officers photographed evidence and dusted every single surface for prints. Sarah knelt carefully down beside the body, quietly noting the strange and troubling absence of blood around the deep wound. The victim had clearly died somewhere else entirely before someone had carefully moved his cold body here after death occurred. Six grieving family members waited in the drawing room, each one hiding dark secrets behind their carefully composed, nervous faces. The raging storm outside grew even fiercer, cutting the electricity and plunging the entire manor into complete and utter darkness. When the lights finally flickered back on, the butler was gone, and the killer's deadly game had only just begun.
