Mark Gatiss "has no plans" to do another series of 'Sherlock'.

The 51-year-old screen writer teamed up with his good friend Steven Moffat back in 2010 to create the modern-day adaptation of the drama series, which stars Benedict Cumberbatch as the famous detective, and, although fans are desperate to have another instalment, the writing duo don't know if they're going to pen anymore episodes.

Asked whether 'Sherlock' will return, Mark said on 'Lorraine' on Friday (15.12.17): "We deliberately left it in a sort of happy place where we could go back. We have no plans at the moment. Steven and I are going to do 'Dracula'. I don't know yet [if I'll be in it]. The part I'd like is obviously Renfield, the mad man. That's the best part. We'll see."

It comes just a few months after he admitted that he and Steven were toying with the idea of bringing it to an end because it's so hard to get the schedules of Martin Freeman (Dr. John Watson) and Benedict (Sherlock Holmes) to line up every year.

Gatiss said recently: "It's not lack of will - it's a nightmare to schedule. It was very, very hard to schedule the last series, because of Martin and Benedict's availability. And Steve's and mine.

"There is always that 'Fawlty Towers' principle of, 'Let's just leave it'. We've had the keys to Baker Street for a while, but one of the wonderful things is that they're always shared. They were shared while we were making it. There's nothing wrong with saying, 'That was our version, somebody out there go and do their version'."

However, it seems Gatiss and Moffat have different views as the 56-year-old television writer is adamant that there will be another instalment of 'Sherlock' - but it won't be anytime soon.

He said: "We did [the last series] a year ago, just about, and I've been flat-out on 'Doctor Who' ever since. So I haven't really thought about it. Mark [has] been doing other stuff as well, so we haven't sat down and had a proper talk about what we would do with another series.

I assume we will. I sort of assume we'll come back."
