Mist clings to slate eaves. Grandfather’s old clock chimes nine. Cold seeps through stone halls. Maid drops her tea tray. A scream tears thin air. Library floor holds their master. Steel blade juts from back. The young heiress freezes upstairs. Guests pour from dining halls. No one spots the lock. A faint click latches closed. Wine stains his white cuffs. Footprints fade by the door.
