The rain hammered against the library windows as Detective Mara Quinn stared at the body slumped over the mahogany desk. A silver letter opener protruded from his chest, and dark blood pooled slowly across the unfinished will beneath his hand. Outside, thunder rolled over Blackwood Manor while seven nervous guests waited silently in the hall, each hiding something dangerous tonight. Mara noticed the grandfather clock had stopped at midnight, its glass shattered, its brass pendulum swinging faintly despite the stillness. On the floor beside the victim lay a single red glove, still damp, smelling faintly of lavender perfume and smoke. She knelt carefully, lifted the glove with tweezers, and wondered which guest had entered this room and never truly left.
