Dusk paints the old library’s dust-caked window sills bright red. A crumpled man slumps atop a leather-bound poetry collection now. A broken quill clatters from his lax, ink-stained right hand. A distant clock’s chime echoes through empty, shadowed book stacks. A half-opened letter flutters where a hidden observer once stood.
