Steven Moffat, who helmed the Matt Smith and Peter Capaldi years on Doctor Who, has announced another project with the BBC. It’s a miniseries called Inside Man, and we’ve got all the info right here…

TV Wise reports that Moffat wrote the four-part script on spec, which means that he came up with the idea and penned the whole thing before bringing it to the BBC to see if they liked it. And, as it turns out, they did like it.

The story of the show has two main plot lines: there is a prisoner on death row in America, and a woman trapped in a cellar under a vicarage in the UK. These stories will intersect in unexpected ways, we’re told.

Piers Wenger, drama controller at the BBC, said this about the news: “In our ongoing relationship with Steven and Sue [Vertue, Moffat’s producing partner], they sent us this mini-series which Steven had written on spec and we commissioned it instantly. The script is a page-turner and grips you from the outset, and Charlotte [Moore, BBC director of content] and I couldn’t resist bringing this story to BBC One.”

Moffat, who also co-created Sherlock for the Beeb, is working away on another project as well: he’s teamed up again with his pal Mark Gatiss to make a new TV version of Dracula.
