At dawn, the manor bell rang without anyone pulling it. Inspector Vale arrived before servants discovered Lady Morrow’s body upstairs. She lay beneath her portrait, clutching a silver button tightly. Every window remained locked, though muddy footprints crossed carpets inside. Her nephew claimed the storm had drowned every suspicious sound. Yet thunder had ceased exactly one full hour before midnight. On the library desk, fresh ink spelled one name clearly. It belonged to someone already buried in the churchyard outside.
