The rain hammered hard against the tall windows of Blackwood Manor as Detective Sarah Chen stepped out of her car. A nervous young constable waited beneath the crumbling stone archway, his flashlight trembling slightly in his cold and shaking hands. He led her slowly down a long, dark corridor lined with portraits whose painted eyes seemed to follow them both. The study door stood open wide, and the smell of expensive cigars mingled with something sharp, metallic, and deeply unsettling. Lord Edmund Blackwood lay sprawled across his priceless Persian rug, a silver letter opener buried deep within his broad chest. His glazed eyes stared upward at the distant white ceiling, frozen forever in a mask of pure, unmistakable, genuine terror. Sarah knelt down beside the cooling body, noting how the victim's pale fingers clutched a torn piece of lavender silk. The marble fireplace still held faintly glowing embers, though the household staff swore that nobody had entered here since dinner. Someone had violently overturned the enormous mahogany desk, scattering white papers like dead autumn leaves across the worn stone floor. A single tall window stood open behind the heavy velvet curtains, letting the storm's icy wind into the dark room. But the soft ground beneath that open window showed no footprints in the mud, only the delicate tracks of birds. Sarah pulled on her blue gloves and reached carefully for the scrap of silk, but the young constable suddenly gasped. He pointed with one unsteady hand toward the stone fireplace mantel, where a fresh note had appeared from somewhere unseen. The crisp paper bore just one line written in elegant crimson ink that gleamed wetly beneath the bright flashlight's beam. It read, "The third one was always my absolute favorite, Detective, but you will never, ever prove a single thing." Sarah felt the familiar cold weight settle deep into her stomach as she realized the killer had expected her here. Outside, a bolt of lightning illuminated the manor's shadowed grounds, and somewhere in the darkness, a woman began laughing softly.
