David, I've seen the film with Sean Connery, (Der name der rose) haven't read the book yet though
I remember it had quite a few similarities to the Sherlock Holmes stories, Sir William of Baskerville is the most obvious similarity.
Elph, the Number One (Ladies) Detective Agency is a great read, and the film/series was good as well. Worth a look
I am gathering quite a reading list for the half term!
