The ornate clock strikes midnight with a hollow, solemn tone. Detective Miles dropped his cigarette, crushing it with his heel. A single light glowed from the mansion's top-floor window. He climbed the stone steps, his breath clouding the cold air. The heavy oak door swung open before he could knock. A pale-faced butler gestured silently, his hands trembling with fear. They proceeded down a long hallway lined with grim portraits. Every shadow seemed to hold its breath as they passed. The library door was ajar, spilling a pool of lantern light. Lord Ashton lay still on the Persian rug, eyes wide. A single crimson stain bloomed across his white silk waistcoat. No weapon was visible in the quiet, book-lined room. The butler finally spoke, his voice a thin, reedy whisper. "He was alone in here for hours, I swear it." Miles knelt, noticing the fragile glass vial immediately. It was empty.
