Rosie Walker

Rosie Walker is a novelist of five psychological thrillers: 'The Bride's Secret' (2025), 'My Husband's Ex' (2024), 'The Baby Monitor' (2024), 'The House Fire' (2022), and 'Secrets of a Serial Killer' (2020). Her sixth book, 'Not My Sister' comes out in March 2026.

Her books mostly explore dark domestic themes: secrets, lies, affairs and revenge. But in real life Rosie is a cheery person who loves rom coms, beach holidays, reality TV, and dog walks by the sea. She lives in Edinburgh with her husband, daughter, and their dog.

Rosie has a Masters in Creative Writing from the University of Edinburgh and an undergraduate degree in Psychology from Lancaster University.
