The clock stopped at midnight, though nobody heard it break. By morning, Eleanor Vale lay dead beneath the conservatory orchids. Her silk gloves remained spotless; the marble floor was bloodied. Inspector Marsh arrived before the servants finished whispering their suspicions. Someone had locked the conservatory door from the inside, apparently. But the only key rested inside Eleanor’s tightly closed fist. Outside, fresh footprints crossed the snow, ending beneath dead roses. Her husband claimed he slept upstairs, dreaming of warmer places. The gardener said nothing, yet kept watching the stopped clock. When Marsh touched its hands, something rattled behind the face. He opened the case and found a tiny brass button. Across its surface, someone had scratched a single word: Mother.
