At midnight, the locked conservatory began ringing its silver bell. Inspector Vale arrived before the household discovered Lord Ashcombe’s body. He lay beneath the orchids, smiling through a crimson wound. Beside him, wet footprints ended abruptly against the locked door. On the glass, someone had written Miriam in his blood. Miriam entered quietly, carrying one candle and yesterday’s folded newspaper. Then the dead man’s pocket watch chimed thirteen impossible times. Everyone stared, except Miriam, who whispered, “It has started again.”
