IMO, it's all in the telling/revealing of it.

Start with the obvious crime scenario. Twist it. Obscure it. Create false leads. Cover it up. Then play it backwards and there you go.

Bladerunner, Fletch, and others combine the noir P.I. genre with others.

Almost want to try to do another cyberpunk noir (plus activism) screenplay. Maybe a workshop on SubMatrix to generate later in A.I.
