Terrance Dicks (in-universe)

Terrance Dicks was an author and writer for the Doctor Who series in the 20th century.

Biography
After a Doctor Who fan managed to contact 1970s UNIT and discussed 2020 with the Third Doctor, Jo Grant and the Brigadier, Terrance Dicks, also on the UNIT line, complimented the Doctor, Jo and the Brigadier's wise words and then called for a round of tea. (WC: U.N.I.T. On Call)

He wrote one-hundred and fifty novelisations, all of which were once owned by Paul Magrs. One of these novelisations heavily contradicted another novelisation, "Doctor Who in an Exciting Adventure with the Daleks", at least by the Eighth Doctor's viewpoint. (PROSE: Bafflement and Devotion)

Legacy
There was once a "Terrance Dicks Library" located in St Luke's University. (COMIC: The Lost Dimension)

Behind the scenes

 * The "novelisations" that Terrance wrote are clearly intended to be Target novelisations, however this isn't explicitly stated in Bafflement and Devotion. In the real world, Dicks was credited on 38 of the around 150 original titles, still far more than any other writer in the range.
 * Dicks made a vocal cameo in WC: U.N.I.T. On Call, voiced by Jon Culshaw.
