The rain lashed fiercely against the windows of the ancient, isolated mansion on that dark and bitterly cold December night. A lone figure approached the grand oak doors, clutching a damp coat in trembling hands under the flickering streetlamp outside. Inside, muffled conversations and clinking glasses hinted at a lavish party already in full swing despite the late hour's gloom. Detective Hartwell paused, removing his hat to study the mansion’s elaborately carved façade bathed in dim light before stepping forward. The butler’s face was unreadable as he ushered Hartwell into the smoky foyer, redolent with aged whiskey and expensive perfume. Whispers ceased abruptly as Hartwell’s sharp gaze swept across room, lingering on the host’s unusually pale complexion and fraught demeanor.
