Sarah Pinborough writes psychological thrillers, horror and speculative fiction known for unsettling relationship dynamics and sharp reversals. Behind Her Eyes follows Louise, her psychiatrist boss David and his wife Adele through an affair and friendship that gradually become much stranger than an ordinary domestic triangle. The novel begins like psychological suspense but introduces a speculative element that changes how earlier events are read. Insomnia centres on a woman approaching the age at which her mother experienced a breakdown, while earlier books such as The Death House and the Dog-Faced Gods trilogy move more openly into horror or dystopian territory. Pinborough’s prose is fast, dark and twist-driven. Her work sits within psychological thriller, domestic suspense and supernatural thriller. Behind Her Eyes is the defining entry for readers who like genre boundaries shifting underneath an apparently familiar relationship plot. Read more Less
