- You may be looking for the art department crew member of the same name.
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 was approached by Big Finish and displayed interest in writing for them. Because he had started the trilogy with Full Circle, they asked him to write a Companion Chronicles story set in E-Space. The Invasion of E-Space was released in October 2010.
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.
