Rain polished the manor windows while Inspector Vale counted thirteen guests circling a dinner table set elaborately for fourteen places. At midnight, thunder silenced the orchestra, and every candle vanished except one trembling beside Lord Ashcombe’s suddenly empty chair. Then the grandfather clock chimed backward, revealing scarlet footprints leading from the locked dining room toward the snowbound rose garden. Nobody moved until Lady Ashcombe whispered that her husband had been dead upstairs since dusk, dressed for tomorrow’s funeral already. Inspector Vale lifted the abandoned glass, smelled bitter almonds, and noticed lipstick matching none of the women seated there tonight. Outside, beneath the black roses, something heavy struck the frozen earth three times, then began scratching upward with frantic purpose.
