Which Roald Dahl novel was published posthumously in 1991?

Roald Dahl’s novel published posthumously in 1991 was The Minpins.

The Minpins was published in the United Kingdom in 1991, after Dahl’s death in November 1990. It tells of Little Billy, who enters a dangerous forest and encounters the tiny Minpins, who live in trees and fear a monster called the Blood-Suckling Stone-Eater.

The book is notable as one of Dahl’s final children’s works. Patrick Benson illustrated the original edition, rather than Quentin Blake, who illustrated many of Dahl’s most famous later books. This difference can cause confusion when readers associate Dahl’s stories with Blake’s distinctive artwork.

The Minpins is sometimes discussed alongside Dahl’s shorter animal and fairy-tale stories, but it is a standalone fantasy novel. Its posthumous publication date also distinguishes it from The Witches, which appeared during Dahl’s lifetime in 1983.
