The creaky attic floorboard hides a crumpled bloodstained old letter. I freeze mid-step, breath catching at the unforeseen grim find. Last night’s missing librarian left this cryptic note for someone. Dust motes dance through slanted sunlight, masking faint death’s scent. A floorboard creaks behind me, signaling an unseen watcher’s presence.
