The rain lashed against the cold glass of the manor. Dark shadows stretched across the floorboards of the study room. Lord Harrington lay slumped over his desk in total silence. A silver letter opener was buried deep within his chest. The heavy scent of metallic blood filled the stagnant air. Thunder rumbled loudly while lightning flashed through the open door. Footsteps echoed softly from the long hallway near the stairs. Someone was lurking in the dark corners of the house. The killer had not yet found a way to escape. Secrets would soon emerge from this night of tragic death.
