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. Smith remains a great fan of Doctor Who, and still attends "Big Finish Day", a UK convention dedicated to the Doctor Who audio CD dramas he has written for.
