Mark Leggatt – Editor

I'm an editor and manuscript assessor, and passionate about making your novel ready for the market. My clients include #1 bestselling books.

Overview

I'm a publishing professional, editor and manuscript assessor, and specialise in detailed manuscript assessments for clients in the UK, EU and North America.


I love to work with debut authors and show them the route to taking their book up to the level required for publication. It's hard work, but great fun.


I recently assessed and edited the #1 bestselling Sci-Fi/Techno-Thriller on Amazon, ARTIFICIAL WISDOM by Thomas Weaver. This will be republished in the US & UK by Penguin Random House in 2025.


I've also recently completed the assessment and final edit of EXIT WOUNDS for crime author Neil Broadfoot, which will be published by Hachette in January 2025.


Several of my authors have gained agents in the US and UK, and I have wide experience in working with leading literary consultancies. Author testimonials are available on request.


As a prospective client, I have stood in your shoes, having taken professional advice at the start of my career, and I've never looked back. There are reasons why a good book is a good book, and I love to pass on all the experience I've gained in my career.


When I'm not assessing and editing, I'm the author of four novels, and topped Blackwell's bestseller charts on two occasions. My latest novel PENITENT was longlisted for the McIlvanney Prize, the Scottish Crime Book of the Year 2023, and reviewed in the national press.


I am a member of the Chartered Institute of Editing and Proofreading.


Testimonials

"Mark is first and foremost a pleasure to work with. He was as passionate about the project as I was, and he would be upfront when something was not working, but never in a way that demoralized me. He’s a consummate professional who always showed up and brought his full attention to our meetings. I can’t recommend him enough."

Work experience

Self-employed

Jun, 2014 — Present
I provide manuscript and query assessments for both debut and published authors, who require a detailed assessment of their work. This includes commercial potential, strengths, voice and style, dialogue, narrative drive, plotting and structure, and any other area that requires specialist attention. My clients range from California to Canada, and from Spain to Scotland. I assess manuscripts with an experienced eye and a feel for the market. I specialise in Crime, Mystery, Sci-Fi, Fantasy and Thrillers, whether they're international, conspiracy, psychological or technothriller. I have also assessed, edited and developmental edited, five crimes novel for Neil Broadfoot (Hachette) and two for Tom Weaver (Del Rey/Penguin Random House). Finally, I have edited and assessed self-published novels for several authors, including Gabriel Galletti and NS Brooks. Several of my authors have gained agents in the US and UK, and I have wide experience in working with leading literary consultancies.

Having used six editors for my books over time, Mark far outpaces the pack. His original approach was to set up a pre-meeting on line to discuss the work as he saw my manuscript. I wanted an editor and a coach to guide faults I knew rested within my word composition. Yet, some common faults I ha...

Mark is professional and responsive. He has a way of giving you the gut punch you need as a writer without making you feel like a failure. I would 100% recommend him as an editor, and plan on using him again in the future.
