Terry Pratchett

Terry Pratchett was an author of whom Dudley Jackson was "a devotee". There was not a single book of his that he had not read. (AUDIO: The Eternal Summer)

Behind the scenes

 * Sir Terry Pratchett also wrote the introduction to Behind the Sofa: Celebrity Memories of Doctor Who. All profits from the book were donated to Alzheimer's Research UK, a charity he often supported due to suffering from dementia himself.
