I stepped through the rusted screen door into the abandoned diner and spotted the crumpled form behind the soda fountain. A thin strip of velvet rope circled the silent victim’s cold neck, its frayed ends stuck to dried blood smudges. I pulled out my scuffed leather notebook and flipped to a fresh page to jot down every small detail now. The dented coffee pot on the back stove still hummed weakly, having run dry hours before the first night’s shift. A tattered paycheck stub leaned against the sugar shakers on the nearby table, no name or visible address printed there. The distant jingle of a passing ice cream truck cut through the quiet, breaking only a fraction of the stillness.
