Grantchester continues this evening and the episodes are growing ever closer to the final scenes of Reverend Sidney Chambers (played by James Norton).
After almost four years on the detective show, James will be leaving his dog collar behind as he allows another Reverend to take over his place in Grantchester.
While fans are slowly but surely coming to terms with the emotional impact of James’ exit, he has also expressed his thoughts on leaving.
He recently explained quitting was “not an easy decision.”
Speaking to Digital Spy the actor said: “With acting, you can’t become complacent. You’ve got to keep moving forward.
“For me, the priority is always to find a role which is new and unfamiliar and challenging, so that was the problem with staying on Grantchester.
“It was a world I had come to know, and inevitably you begin to learn less, so whilst it was the happiest time I’ve ever had on any set, I realised that it was probably going to lead to being less challenged [going forward].”
James added he would feel a “tinge of FOMO” as the show continues without him.
He added: “It’s like leaving the party early – going home and knowing the party’s going on without you.”
Viewers will see the final scenes for Reverend Sidney in the coming weeks, after his replacement arrives on the scene.
The newcomer, Reverend Will Davenport (Tom Brittney) will make his mark in Grantchester with a new style.
And although he is filling the same slot as Reverend Sidney, he is sure to bring new challenges to the show.
James also appeared on The One Show recently where he explained how making the decision to leave was “heart wrenching.”
He continued: “I’ve said it many times but I’ve never had so much fun on a job as I have in Grantchester… But ultimately you have to keep moving forward.”
James also explained a bit about his final storyline, saying: “After the three series you had a natural end to the storyline with Amanda [Morven Christie].
“It felt like starting a whole other storyline could, potentially, hopefully, take on a few more series.”
But he went on to say another storyline would be “a long commitment” before concluding: “So yeah, on to pastures new, sadly. But yeah.”
Tonight’s episode will see Sidney losing himself in drink as he begins to feel sorry for himself.
But the whiskey quickly takes its toll as he discovers he was the last person to see a local young woman alive.
Grantchester season four starts tonight on ITV at 9pm.
