William - The Detective is a book in the Just William series written by Richmal Crompton. Modern editions contain ten stories; it originally contained eleven: The eleventh, entitled William and the Nasties was removed from the book later on because, though ultimately anti-Nazi, it was considered inappropriate after the Holocaust (it has been retained, however, in the Israeli edition). William and the League of Perfect Love has also been removed from some editions under pressure from the animal-rights activists it satirizes.
