Series 2 began in May 2008, so we are beginning to wonder when the show is going to begin again?

Quite frankly, we don’t know.

But lets look at the evidence…

Filming is complete, and there has been plenty of time for post production already.  That suggests pretty soon.

The DVD of series three will be released on 23 November, so episode 6 will have to be shown before that. UPDATE: This now says Dec 7, and I would not be surprised to see it change again.

So if we assume that the last episode will be shown the week beginning 16 November, and we know that there are 6 episodes, that would mean that episode 1 would be shown in the w/b 12 October.

So that is our prediction, can you do better?

Now the next question is BBC One, Two or Three? UPDATE: BBC Press Offfice says BBC One

Wikipedia is going for “Late October 2009″.
