At midnight, the lighthouse keeper discovered blood beneath his door. The victim lay upstairs, though every staircase step remained spotless. Outside, the foghorn sounded three times, then stopped abruptly. Detective Mara Vale arrived before anyone reported a crime publicly. She recognized the dead man's watch from her own desk. Inside its cracked face, someone had tucked a tiny photograph. Mara turned it over and saw tomorrow's date written there.
