Terrance Dicks (in-universe)

Terrance Dicks was an author.

He wrote one-hundred and fifty novelisations, which were once all owned by Paul Magrs.

One of these novelisations had something to do with the Daleks, as the book "Doctor Who in an Exciting Adventure with the Daleks" heavily contradicted it, at least by the Eighth Doctor's viewpoint. (PROSE: Bafflement and Devotion)

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.
