Rain lashed against the old mansion's leaded windows. Cobwebbed shadows danced in the flickering candlelight glow. A hushed gasp echoed through the grand, silent hall. Sir Reginald lay sprawled, a crimson stain blooming outward. His pearl monocle had fallen from its proud socket. A single, ornate letter opener lay nearby. Who could have done this terrible, bloody deed? The storm outside seemed to mirror the internal dread. Secrets were buried deep within these ancient walls. The night had just begun its dark, grim work.
