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

Publish with confidence

Want to craft a novel that's ready for readers? I’m Louise Harnby, a fiction editor who'll help you prepare your book for market. 

​Work with a genre specialist

You write crime fiction, mysteries, thrillers or suspense. I specialize in editing those genres. That means your novel’s with an editor who gets you and knows the landscape.

​Craft sentences that pop

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

Read six tips to work out if we're a good fit.

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.

Emotionally intelligent editing

When you work with me, you work with me – not a subcontractor, not an agency, not a generative AI. Just Louise. From the beginning of the project to the very end.

​You’ve brought your human emotional intelligence to the writing. I’ll bring mine to the editing.

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.

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.
