The BBC detective drama's upcoming fourth series has a certain feeling about it, according to the Dr John Watson actor. And no, it's not the good kind.
"Life does sometimes have a way of telling you, this is probably it now," Freeman recently told Jim Norton & Sam Roberts's SiriusXM radio show (about 2 hours, 12 minutes in).
"And I am never ever afraid of things ending. I mean I am not looking forward to life ending or love ending, but things that we make, should end."
That's great and everything, Martin, but what about us fans?!
He went on to say that he would rather the series finish at its peak — and is definitely not interested in the business of reunions.
"We all know the alternative is that you leave people wanting less and saying, 'I wish you'd stopped five years ago,' and that's not a good place however much money you have made," he said.
"I believe in the finite nature of things and I like things being left alone. I have never been a massive fan of reunions."
So, seeing as it might be all we have to savour, here's everything you need to know about Sherlock series four — plus the name of the Watsons' baby (who we may not even get to see grow up?!).
Sherlock – also starring Benedict Cumberbatch, Amanda Abbington and Toby Jones's infamous new villain Culverton Smith – returns with 'The Six Thatchers' on January 1, 2017 on BBC One in the UK and PBS in the US.
