There was a tweet the other day from someone asking Peter Harness if he was writing an episode of Doctor Who. He replied with “Nosey Parker”, but didn’t deny it. So is the Case Histories and Wallander writer penning one for Doctor Who? Who knows. Even if he is, that doesn’t mean it will be one airing this season.
Other confirmed or speculated writers for series 8 include Steven Moffat, Mark Gatiss, Phil Ford, Gareth Roberts and Steve Thompson.
