Crime Fiction: what makes the plot work
Crime Fiction delves into the complexities of crime, law enforcement, and the human psyche, often involving detectives, criminals, and unsolved mysteries.
Make the place part of the crime
Crime fiction is often loved for its sense of place. Ian Rankin's Rebus novels are about Edinburgh as much as any single case, and Dennis Lehane's Mystic River is bound to the Boston neighborhood where three boys grew up. Ask what your setting's money, history and grudges have to do with the crime.
Give real pages to the aftermath
A murder doesn't end when the body is found. Families split, businesses close, witnesses move away. Some of the strongest crime novels spend time with the people left behind, and their grief and suspicion are as dramatic as the investigation.
Give the criminal an urgent reason
S. A. Cosby's Blacktop Wasteland follows Beauregard 'Bug' Montage, a gifted getaway driver who has gone straight until money trouble at his garage pulls him back for one more job. The motive is ordinary and pressing, which is why readers stay with him. Rent, medical bills and family loyalty make crime understandable without excusing it.
Choose whose story it is
The same crime reads very differently from the detective's desk, the criminal's car or the victim's sister's kitchen. Pick the point of view with the most at stake, then consider a second one that sees what the first can't. Multiple viewpoints suit crime fiction well, as long as each one changes what the reader understands.

Questions about Crime Fiction plots
Is crime fiction the same as mystery?
They overlap, and bookstores often shelve them together. Mystery centers a puzzle and its solution. Crime fiction is wider: it can follow the criminal, the victim or a whole community, and the reader may know who did it from page one. Many crime novels care less about who than about why, and what happens next.
How dark can crime fiction get?
As dark as the story needs, and readers of noir and gritty crime expect a lot. Where many readers draw the line is gratuitousness: violence described for its own sake, especially against children or animals, loses people fast. Violence kept off the page with consequences shown on it is often more powerful.
What is noir?
Noir is crime fiction with a fatalistic streak, where protagonists are compromised and things tend to end badly. Classic American examples include James M. Cain's The Postman Always Rings Twice and Jim Thompson's The Killer Inside Me. Noir has since spread to every region, from Scandinavia to the rural American South, but the sense of doom stays.
