Cold rain battered against the dark glass of Blackwood Manor. Inside the library, a grandfather clock ticked with heavy dread. Lord Harrington lay motionless across the stained Persian rug tonight. A silver letter opener was buried deep inside his chest. Fresh crimson blood slowly soaked through his crisp white shirt. His cold, stiff fingers tightly gripped a torn paper note. Footsteps echoed down the hallway before the heavy door opened. Detective Miller stepped inside and surveyed the grim, silent room. The killer was clearly someone who still remained within reach.
