Fog smothered the riverside mansion. Detective Mara arrived before dawn. Windows glowed silent, watchful inside. A servant wrung shaking hands. He led her upstairs, whispering. The study door stood ajar. Blood darkened the Persian rug. Lord Hargrove lay facedown, motionless. His pocketwatch ticked, accusingly loud. On the desk, letters burned. Mara noted ash and perfume. Outside, footsteps fled into fog.
