‘Sherlock’ co-creator Steven Moffat: ‘We’ve already plotted out series four and series five’

Series three concludes this week (January 12)

Sherlock co-creator has revealed that he and [b]Mark Gatiss have already plotted out ideas for series four and five of the show.

The third series of the BBC One programme will conclude this week (January 12) but, at a recent screening of the series three finale, Moffat said that they had already begun thinking of ideas for future follow-ups.

“Rather excitingly, Mark and I, for no particular reason, we just got out of the rain and sat at the top of the [Sherlock] production bus and we just started plotting out what we could do in the future,” said Moffat, accordng to Digital Spy. “And we plotted out the whole of series four and five.

He added: “So we have got plans – but our plans don’t tend to be, ‘Let’s blow up the world or cast the most famous person in the world’, they tend to be, ‘What exciting twists and turns can we add to this?’ And I think we’ve got some crackers. The ideas we had that day, I thought, were the best we’ve ever had.”

Sherlock returned on January 1 of this year, with viewers tuning in to see how the sleuth had faked his own death after jumping off a hospital roof at the end of series two. A teaser trailer for the final episode of this run, ‘His Last Vow’, was unveiled earlier this week – click below to watch.
