The rain-soaked street reflected the flickering gaslight dimly and coldly. Inspector Ashworth stepped from the carriage with a tight grimace. A still body lay crumpled on the cold wet cobblestones. The victim's hand still clutched a single blood-stained iron key. Inspector Ashworth knelt beside the cold and pale twisted corpse. His old pocket watch read exactly three minutes past midnight. The only sound was steady drip from the nearby gutter. A single footprint led away into the alley's deep darkness.
