It used to be claimed that there were just two requirements to be a "companion" in Doctor Who. The first was to be able to scream and run at the same time. The second was to be able to say "What do we do next, Doctor?" with conviction!
Following his highly successful book on the six Doctors, Doctor Who: The TARDIS Inside Out, John Nathan-Turner examines the Doctor's companions. Thirty companions are mentioned, and fifteen are discussed in some depth. The text is complemented by Stuart Hughes' beautiful full-colour and black and white illustrations.
