Line Editing for Crime, Mystery and Thriller Writers

Professional Techniques for Self-Editing Fiction

A brand new crime and thriller writing resource coming in 2026 ...

Learn how to write killer sentences that keep readers turning the page​

This practical guide will show you how to line edit crime, mystery and thriller fiction with confidence.

You'll learn how sentence structure, word choice, rhythm, pacing, viewpoint, foreshadowing and misdirection deepen reader immersion and sharpen storytelling impact. We'll also explore character voice, violence and pain, first lines, fight scenes, chase scenes and much more.

Above all, you'll discover how sentence-level craft can heighten tension, sustain suspense and keep readers turning the pages long into the night.
Editing Fiction at Sentence Level

Why trust my advice?

I'm a professional fiction editor who's been helping writers tell better stories for twenty years. Here are four things worth knowing about me:
  1. I work exclusively with indie authors.
  2. I'm a genre specialist. Crime, mystery, suspense and thriller fiction are my thing.
  3. Line editing is my passion. Helping writers master sentence-level craft is one of the most rewarding parts of my job.
  4. This isn't my first rodeo. You might already have read Editing Fiction at Sentence Level. It's my bestselling book by a mile, and this new guide takes the conversation much further for crime, mystery and thriller writers.
