Heavy rain pounded against the cracked glass of the window. Detective Vance stepped silently across the dark and dusty floorboards. Lord Harrington sat completely motionless behind his grand mahogany desk. A silver dagger was buried deeply inside his velvet coat. Dark red blood dripped slowly onto the expensive Persian rug. The victim clutched a torn photograph in his cold hand. The grandfather clock chimed midnight through the vast quiet mansion. Footsteps echoed down the hall right behind the watchful detective.
