The rain hammered hard against the tall windows of Blackwood Manor as Detective Sarah Chen stepped carefully over the threshold. Old Lord Edmund Blackwood lay sprawled across the Persian rug, a silver letter opener still buried deep in his chest. Mrs. Whitmore, the trembling housekeeper, had discovered the body at dawn, her piercing screams echoing through the manor's empty halls. Chen knelt beside the corpse, noting the frozen terror etched into his pale face and the fireplace still burning quietly. Six weekend guests had spent the night under this roof, and each one now waited nervously in the drawing room. A massive fallen oak tree had blocked the only road, and the storm had severed every telephone line for miles. Every lamp in the study had been extinguished, yet one candle still flickered near the overturned antique mahogany writing desk. Chen noticed the wall safe behind the portrait hanging open, its precious contents vanished without leaving even a single fingerprint. Scratched deep into the dusty stone mantelpiece, someone had left behind a single message that made Chen's blood run cold. It read simply "Soon," one word promising much more blood, carved by a hand that showed no signs of hesitation. The killer still remained inside the manor, Chen realized, watching and waiting patiently behind one of six seemingly innocent faces.
