The gray fog rolled thick over Blackwater Manor as Detective Elena Marsh stepped slowly from her car into cold darkness. The tall front doors stood wide open, which struck her immediately as wrong, because wealthy people never left them unlocked. Inside the grand marble foyer, a very young officer waited nervously, his face pale beneath the harsh light of chandeliers. He led her down a long hallway lined with old portraits, their painted eyes seeming to follow her every step. The study door swung slowly open onto chaos: overturned furniture, shattered glass, and the body of old Lord Ashworth himself. He lay sprawled across the expensive Persian rug, a gleaming silver letter opener buried deep between his prominent shoulder blades. Elena pulled on her blue latex gloves and knelt beside him, noting that his cold fingers clutched torn scarlet silk. The antique clock on the mantel had stopped at exactly midnight, though the whole murder seemed far messier than that. Somewhere upstairs, a single floorboard creaked loudly, and every officer in the room froze, hands drifting toward their holstered weapons. Elena drew her service weapon slowly and climbed the stairs, aware that the killer might still be inside the house.
