Gareth Roberts writing City of Death novelisation

Writer Gareth Roberts has confirmed on Twitter that he is currently writing a novelisation of the 1979 serial City of Death:

KippyWoo: Will you be doing any more novelisations after Shada e.g. City of Death?
Gareth Roberts: Oh, I feel like blabbing ... I'm writing City Of Death right now, should be out next year.

Most Doctor Who serials from the series' original run (1963–1989) were novelised between 1964 and 1993, except for two Dalek serials by Eric Saward and three serials written or cowritten by Douglas Adams. In 2012, BBC Books published a novelisation of the uncompleted serial Shada by Roberts. The televised version of City of Death was credited to the pseudonymous "David Agnew", because Adams (who was then serving as Doctor Who's script editor) heavily rewrote the original script by David Fisher. Adams later used elements of both City of Death and Shada in his 1987 novel Dirk Gently's Holistic Detective Agency.

As indicated above, Roberts' novelisation of City of Death is expected to be published in 2014.
