The fog crept through the alley as Miss Bell found the body beneath a broken lantern beside an overturned bottle. Her candlelight flickered, revealing muddy footprints, one pearl earring, and the cold hand of a murdered man inside that alley. Outside, midnight church bells tolled, while the inspector noted the missing key from a locked study door without any witnesses.
