Sherlock producer Sue Vertue has confirmed that there will be a second series of the modern-day adaptation.
Speaking on BBC Breakfast, Vertue - who appeared with husband and show co-creator Steven Moffat - revealed that an agreement has already been made with the BBC.
"There will be more.We're having a meeting, just to sort of talk about how many and when really. Steven and Mark [Gatiss] are both busy," she said. "Obviously Steven is doing Doctor Who as well so it's just when we are going to do them."
Presenter Sian Williams asked Moffat why only three initial episodes had been commissioned, to which he replied: "They're 90 minutes long! Three 90-minute episodes, that's longer than a sitcom, stop complaining."
BBC head of drama Ben Stephenson recently warned that any episodes of the show will not air for "at least a year".
Sherlock ended its three-episode run on Sunday night watched by 7.3 million viewers.
Some are born great, some achieve greatness and some have greatness thrust upon them.
The rest of us are a bit crap.
