At midnight, the old lighthouse flashed warnings nobody could decipher. Detective Mara Voss watched its beam sweep across black water. Three hours earlier, its keeper had been found brutally murdered. His body lay upstairs, surrounded by thirty identical stopped clocks. Every clock showed the same time: eleven minutes after midnight. Yet the coroner insisted death had occurred before sunset yesterday. Across the dusty windowsill, salt crystals spelled a woman's name. Mara recognized it immediately: her sister had vanished last winter. Outside, the lighthouse flashed again, though nobody touched its controls. Then someone behind her whispered softly in her sister's voice.
