IT WOULD be fair to say that Beltempest is a Doctor Who novel with a high-concept science fiction idea at its heart. There's no moustache-twirling villains, or bases under siege.

Not only is Beltempest a story of note, but this is an episode with a difference - we don't have a 'live' interview with author Jim Mortimore, but he kindly agreed to record his answers to the questions, which we sent him, and we've created a full chat with him.

As ever, Steve Cole tells us about things from his side as the range editor too, for another engrossing chat.
