I'm back home, refreshed, excited and desperately sad about Doctor Who. Are my Saturdays to be changed forever? No more servings of David Tennant? Will the next doctor in fact be a woman?

Actually, you should watch Doctor Who with the eye of a writer. There are many techniques used by the fabulous Russell T Davies and his successor Stephen Moffat that you can learn from. Particularly watch the Doctor Who Confidential which immediately follows Doctor Who on BBC 3. The writers often talk about how they do it. One comment that sticks in my mind is that if no one has died in the last 10 pages, Russell has to kill someone off. Like Raymond Chandler and enter a man with a gun.
