There is more than one author with this name Andrew Smith wrote the Doctor Who television story Full Circle and its novelisation. At the time of initial broadcast, he was the youngest writer to contribute to the TV series. Smith submitted his work to more than one Doctor Who script editor. They replied with "positive criticism". Finally he sent The Planet that Slept, which became Full Circle. Shortly afterwards, he became a police officer, spending a long time in that career.
