The Name of the Rose

Who is killing monks in a great medieval abbey famed for its library - and why? Brother William of Baskerville is sent to find out, taking with him the assistant who later tells the tale of his investigations. Eco's celebrated story combines elements of detective fiction, metaphysical thriller, post-modernist puzzle and historical novel in one of the few twentieth-century books which can be described as genuinely unique.
The Name of the Rose was made into a film in 1986, starring Sean Connery and Christian Slater and directed by Jean-Jacques Annaud.
