Lies He Told Me is a gripping psychological thriller co-authored by James Patterson and David Ellis, published by Little, Brown and Company. The novel follows Marcie Bowers, a former big-city attorney turned small-town family lawyer, and her husband David, the beloved owner of the local pub in Hemingway Grove, Illinois. When David heroically dives into the Cotton River to save a drowning stranger, his act of bravery goes viral — but the sudden spotlight proves dangerous.

As David's face floods every news outlet, Marcie begins to question everything she thought she knew about the man she married. The story unspools in taut, fast-paced chapters that alternate perspective and escalate tension with each revelation. Praised by Freida McFadden, #1 bestselling author of The Housemaid, as "a roller coaster from start to finish," the novel delivers a final twist that has earned widespread acclaim.

The hardcover edition runs 384 pages and was released on September 30, 2024. A trade paperback edition (400 pages, ISBN 9781538710708) followed in October 2025. James Patterson is the recipient of an Edgar Award, ten Emmy Awards, the Literarian Award from the National Book Foundation, and the National Humanities Medal. David Ellis is a justice of the Illinois Appellate Court and an Edgar Award-winning novelist.
