The dark stormy night concealed the old manor's crumbling walls and the gaslight flickering weakly within its many ancient windows. Detective Harper arrived alone, his trench coat drenched, and he squinted through the downpour at the very imposing oak door. He immediately noticed the faint smell of blood, a coppery tang that hung in the air despite the cleansing rain. The massive oak door slowly creaked open before he could knock, revealing a dimly lit foyer with a flickering chandelier. A silent butler slowly gestured him inside, his face pale and completely expressionless, as if carefully carved from old wax. Harper followed the butler down a very long corridor lined with portraits of ancestors with stern faces in gilded frames. The air grew much colder as they approached the library, where a single body lay sprawled on the polished floor. A single brass candelabra sputtered on the desk, casting many dancing shadows over the deceased gentleman's terribly distorted pale visage. Harper slowly kneeled beside the corpse, carefully observing the deep wound on its neck and the strange symbol drawn nearby. The butler whispered softly that the victim was Lord Ashworth, and the murder weapon remained completely unknown to anyone here.
