Rain battered Blackthorn Manor as guests gathered for supper. Sir Alistair Vale arrived late, smiling beneath thunderclouds. His velvet coat concealed letters, debts, and dangerous promises. Inside, candles trembled beside portraits of unsmiling ancestral judges. Mrs. Finch served wine with hands unusually pale tonight. At midnight, the library bell rang once, then stopped. Guests found Sir Alistair sprawled beneath the shattered clock. A silver letter opener gleamed between his motionless ribs. Nobody admitted hearing footsteps, though mud marked every corridor. Detective Mara Venn closed the doors and counted suspects.
