At midnight, Detective Mara Vale arrived at the manor, where every clock had stopped at eleven minutes past nine. The victim lay beneath the grand staircase, one hand clutching a playing card, while rain tapped against the windows. Mara counted thirteen guests in the drawing room, though the dinner register listed fourteen names beneath the date's red ink. No one admitted knowing the missing guest, and no one could explain why his coat was hanging beside the door. Then the youngest maid whispered that the card belonged to a deck she had locked in the study yesterday afternoon. Mara turned it over and found, written across the back, the exact time that all the clocks had stopped.
