Fiction editing and proofreading ​for crime, mystery, suspense and thriller writers

Publish with confidence

Writing a crime novel, mystery, thriller or suspense story? I’m Louise Harnby, a specialist fiction editor who helps authors strengthen their manuscripts at sentence level and prepare them for readers.

​Work with a genre specialist

You write crime fiction, mysteries, thrillers or suspense. I specialize in line editing those genres. That means your manuscript is in the hands of an editor who understands the genre, its conventions and what keeps readers turning the page.

​Strengthen every sentence

I’ll work through your narrative and dialogue, focusing on engagement, flow, clarity and consistency while respecting your voice and style. That way, you can concentrate on what you do best – ​telling stories.

I'm a better writer because you edited my book …​
Cooking for Cannibals is a better book because of your careful, professional edit. And I'm a better writer. I can’t think of a higher compliment. But that’s the truth of it ... I'm a better writer because you edited my book.

The impact on the beta reading team has been explosive …
I’ve worked hard on those opening eight chapters. They’ve been adapted in accordance with your suggestions and edits, and the impact on the beta reading team has been explosive. The raw voice of both the narrator and characters was preserved despite such powerful changes.

You are by far the best literary editor I've had. Your interventions are right on target, not to mention that I've learned a lot from your comments. Thank you.

Helped me shed so many of my fears ...
​
​Through all of the changes and feedback I was never once anxious. That you made all of the changes needed with generosity and care is incredible. This is what I want to spend my life doing, and you have helped me to shed so many of my fears about doing so. It means everything. Thank you.

If you want your writing to be better, get Louise to edit it ...​
Louise has the rare ability to refine and polish sentences with a perceptive lightness of touch, revising only where necessary, and somehow, magically, what is left on the page better captures the very essence of exactly what you wanted to say. ​Add that she is a pleasure to work with and clearly loves what she does, and it really does become impossible to find fault with her service. ​In short – if you want your writing to be better, then you need to get Louise to edit it. I can't recommend working with her highly enough.
