Stephanie Glencross An agent with David Higham Associates (see other agents at this agency). About I joined David Higham Associates in January 2018, having previously been the Editor at Gregory & Company Authors’ Agents. I worked alongside Jane Gregory for ten years, helping to build the list of clients and working with the authors on their manuscripts and ideas. I am proud to have edited many award-winning authors including Val McDermid, Mo Hayder, Catherine Ryan Howard, Paula Daly, Tan Twan Eng and Belinda Bauer. I bring a lot of editorial experience to my agenting and love being involved in the editorial process with the authors I represent.Before I became an editor I was at the BBC for a few years, first in the Radio Drama department then in the Story Department of EastEnders. During that time I learned an enormous amount about the power of characterisation and the construction of cliffhangers.I have been privileged to be a judge on the CWA Debut Dagger Award for several years and continue to have a love affair with crime fiction that started with Nancy Drew and was nurtured by Sara Paretsky, Patricia Cornwell and Michael Connelly. This agent may not respond to all queries. After waiting 112 days, assume your submission will not be accepted. Country & Year Established United Kingdom Agent since 2018 Professional Associations Member of AAA AI Policy Human-created work only; no AI use allowed Fiction Open I am obsessed with crime, thriller, and dark commercial fiction. Crime has been my go-to genre as a reader for as long as I can remember. As a student, I worked at Crime in Store bookshop in London, which only deepened my obsession. I’m particularly interested in the way the genre has evolved far beyond any narrow or traditional definition of what ‘crime fiction’ can be.As a result, my list is focused on crime and thriller. I love dark, juicy, and riveting stories: high-concept psychological suspense, clever and satisfying mysteries, and propulsive thrillers with real momentum. I’m especially drawn to work that feels accessible but slightly unexpected – books you tear through at speed, but which still offer a fresh angle, an original lens, or a smart twist on familiar terrain. I don’t have a rigid or prescriptive wish list and genuinely relish being surprised by a manuscript I didn’t know I was looking for.Audience:Open to a broad Audience, including: Adults.

Never pay an agent an up-front fee. That is not how literary agent representation works. Agents earn a commission only after they've landed a publishing deal for you. Also, agents scarcely ever contact writers. If an agent that you haven't queried contacts you about representation, be suspicious. Look up the agent and check if the email address is correct for that agent/agency.
