The grandfather clock in the dim hallway chimed twelve times, mixing with the relentless howling of the autumn wind outside. Sir Charles sat perfectly upright in his favorite leather armchair, but his glassy eyes stared blankly at the ceiling. A single goblet of crimson wine rested on the side table, releasing a faint aroma of sweet, roasted almonds. Footsteps echoed softly upon the polished oak floorboards, stopping just behind the heavy velvet drapes near the locked door. The shadow stretched long across the Persian rug as a gloved hand reached silently down to extinguish the candle.
