At midnight, the manor clock stopped, though nobody touched it. Inspector Vale found Lady Ashcombe beside the locked conservatory doors. Rain blurred the windows, concealing footprints beneath the rosebushes outside. Her teacup remained warm, but every candle had gone dark. Across the room, a violin string trembled without any musician. Then Vale noticed mud drying on the vicar’s immaculate shoes. Nobody spoke as the clock began striking thirteen from upstairs.
