Mark Gatiss has dropped some small clues on his Series 7 episode of Doctor Who.
Gatiss previously penned episodes The Unquiet Dead, The Idiot’s Lantern, Victory of the Daleks and, more recently, Night Terrors.
In the latest Doctor Who Magazine (#443), Gatiss confirms he pitched his latest story idea to Steven Moffat late last year.
He goes on to say that, naturally, he can’t reveal anything yet, except that the episode contains the words ‘meat’, ‘klaxon’ and ‘Vienna’.
No further hints were given, so that’s all we have to go on, for now.
