Dawn seeped over the old red roof, gilding the tall cobblestones, the stillness broken only by a distant rooster's crow. Mrs. Elara sat at the kitchen table, hands folded, a faint smile on her lips, throat slit wide, life draining. A single key, its teeth worn smooth, lay under the salt shaker, a fingerprint smudged on its cold, shiny surface. Detective Voss arrived, his boots crunching frost, a coffee cup in hand, the door creaking behind him softly. On the floor, beside the chair, lay a leather-bound book, its pages open to a poem about stars and secrets.
