The golden clock on the marble mantelpiece chimed twelve times as the heavy velvet curtains swayed in the freezing breeze. Sir Reginald lay slumped across his mahogany desk while a single drop of crimson blood soaked into the expensive rug. The study door stood slightly ajar, allowing a thin sliver of pale moonlight to illuminate the broken glass nearby. Outside, the gardener noticed a shadowy figure sprinting toward the darkened woods before disappearing into the thick and swirling fog. A silver letter opener remained embedded deep within the victim's chest, glinting under the soft glow of the dying fire. Inspector Miller adjusted his spectacles and stepped over the threshold, knowing that everyone in this house had a dark secret. He sighed heavily because he realized that the long night ahead would surely reveal a very clever and ruthless killer.
