Sir Reginald lay dead on the Persian rug in his study, a silver letter opener protruding from his cold chest. Rain lashed against the heavy bay windows as Inspector Sterling stepped into the room and shook his wet, black umbrella. The grandfather clock chimed midnight, its deep resonance echoing through the silent mansion where a clever killer still lingered nearby. A shattered glass of expensive scotch rested by the hearth, spilling amber liquid across the highly polished mahogany floor planks. Sterling knelt slowly beside the body, noting the strange lack of physical struggle and a faint scent of bitter almond. The grim realization hit him that this murder was not a simple robbery but a carefully calculated act of revenge.
