The first thing Inspector Mara Voss noticed was the clock ticking backward above the dead man's carefully arranged breakfast tray. Beyond the darkened windows, Blackthorn Hall slept beneath a sky the color of an old bruise before the sunrise came. Sir Julian lay beside his chair, one hand extended toward a silver bell that remained stubbornly silent throughout the night. A thin line of blood marked his temple, but the pistol lay inside a locked drawer in the study downstairs. His daughter stood in the doorway wearing white gloves and watching the clock rather than her father's pale, still face. The daughter said the cook had found him, although the cook had vanished before anyone thought to summon the police. Then the clock struck seven, and every person in the room heard footsteps moving slowly inside the sealed bedroom wall. Mara drew her revolver, while the dead man's daughter smiled for the first time since the body had been discovered.
