Heavy rain battered the tall windows of the grand library. Detective Miller stood silently above the body on the rug. Dark crimson blood pooled slowly beneath the ornate mahogany desk. A silver letter opener protruded directly from his broad chest. The wealthy host had made too many dangerous enemies recently. Every single guest inside the locked mansion had a motive. Bright lightning suddenly illuminated one muddy footprint by the door. Nervous whispers echoed softly from the crowded hallway just outside. The veteran detective knew the killer was still hiding nearby. Nobody would leave this isolated estate until someone finally confessed.
