Rain hammered mercilessly against the tall Victorian windows while Detective Vance examined the cold corpse lying upon the Persian rug. A silver dagger protruded sharply from the victim’s motionless chest, reflecting the eerie glow of the flickering fireplace nearby. Silence suffocated the grand drawing room completely, broken only by the ticking grandfather clock counting down the remaining hours of midnight.
