Shirley Jackson, the 20th-century horror author, has had a remarkable resurgence in popularity in recent years, with a series of screen adaptations bringing her writing to a new audience. Joan Passey, an academic at Bristol University and co-editor of an upcoming collection of essays on the ‘mother of horror’, selects five books that offer the best introduction to Shirley Jackson’s work.

This year marks the centenary of the birth of the novelist, poet and essayist Muriel Spark, a singular voice of 20th century literature. Her 22 novels are slim and entertaining says Alan Taylor, author of Appointment in Arezzo, but beneath the jeux d’esprit lies a fearsome intellect. Here he selects five of her key works.
