Masters is also known for his eclectic range of non-fiction titles, ranging from the biographies of such diverse personalities as the British secret service chief immortalized by Ian Fleming in his James Bond books (The Man Who Was M: the Life of Maxwell Knight).His children's fiction included teenage novels and the ground breaking Weird World series of young adult horror, published by Bloomsbury. He also worked with children both in schools and at art festivals. Anthony Masters died in 2003.
