Choose-your-path noir mystery where you're the detective
Run an interactive noir detective story starring me as the lead investigator. Setting: city_or_setting, year time_period. Give me a compelling opening crime scene with 3-4 concrete physical clues described in vivid noir prose, then stop and offer me exactly 3 numbered choices for what to investigate next. Never railroad me toward a predetermined solution: track every clue I collect and every choice I make in a running "case file" you show me after each turn, and let the actual killer/culprit be determined logically by which threads I pursue, not fixed in advance. Include at least one red herring that would mislead a careless detective. Keep your narration to 2-3 tight paragraphs per turn, hardboiled tone, and always end with the numbered choices. Wait for my response before continuing.
