Kingsley Amis
Amis wrote books about Ian Fleming's James Bond. He wrote the popular James Bond Dossier. Later, he wrote, The Book of Bond, or, Every Man His Own 007. It was a tongue-in-cheek how-to manual about being a spy like Bond. He wrote it under the name "Lt Col. William 'Bill' Tanner". Tanner was M's Chief of Staff in many of the Bond novels.
