Cold winter rain drummed heavily against the mansion's glass dome. Inside the library, absolute silence blanketed the bloodstained Persian rug. Sir Reginald sat upright, but his eyes were totally lifeless. A silver letter opener was buried deeply inside his chest. Fresh velvet slippers peeked out from beneath the mahogany desk. One expensive crystal glass lay shattered on the hardwood floor. The scent of bitter almonds hovered near the dead billionaire. Outside the locked door, footsteps sounded down the dark hallway. A brass key turned slowly inside the heavy iron lock. Inspector Thomas entered the room and pulled off his gloves. He glared at the corpse and knew everyone was lying.
