Crime & Mystery
The useful bit in crime fiction is often not the laboratory result. It’s the awkward little gap between what a trace can actually prove and what everyone in the room wants it to mean.
That gap is where the tension lives. A fibre, a print, a timestamp, a smear of something on a cuff. Useful, but not magical. The detective still has to do the irritating human work of deciding whether it matters, and why.
Too much forensic certainty and the story starts sounding like a brochure for a testing service. Too little, and the whole case feels hand-wavy. The balance is somewhere in the mess.

For me the bigger risk is when fiction treats the detective as the only person who can read the evidence. In real life, a lab result is often just one more awkward fact in a room full of people making assumptions. The interesting bit is who gets to interpret it, and who benefits from being believed.
The danger is when the story treats the clue as if it has moral authority. It doesn’t. A stain can narrow the field, but it can’t tell you motive, panic, habit, or lie. That’s still the awkward business of people.
Also, for me, the best scenes often come after the evidence arrives, when everyone starts rearranging their certainty to fit it. That’s where the damage gets interesting.
