At midnight, the bell tower rang despite its missing clapper. Inspector Vale found the mayor face-down beneath the clock there. The room smelled of rain, gunpowder, and crushed white roses. No window stood open, yet wet footprints crossed the carpet. Each print ended abruptly beside the locked library door inside. Vale noticed one dry shoeprint pointing toward the fireplace alone. Inside the ashes, someone had hidden a silver wedding ring. The mayor’s wife recognized it, then quietly vanished downstairs alone. But Vale heard footsteps climbing behind the sealed wall again.
