Steven Moffat has promised plenty more shocking developments are in store for Sherlock in the third series.

Speaking to IGN, he teased: “We’ve got a really good framework for [Series 3]. We’ve got a good beginning, a stormer of an end and we’ve got a stunning development in the middle, which is what we’re looking for. We want three must see films!

“Like [Series 2], it will all build up shockingly to the last 20 minutes…”

He also gave his thoughts again on Elementary, the American TV “adaptation.”

“If their show isn’t good, it damages us. I don’t know, what do you imagine I think about it? It’s pretty remarkable, really, I’d say.”
