While Grantchester season 10 has already aired in the US, UK fans have had to wait quite some time to be reunited with Geordie and Alphy, whose relationship is put to the test in the latest instalment.

Speaking to RadioTimes.com and other press ahead of season 10's UK debut, leads Robson Green and Rishi Nair teased a "secret... [that] really fractures" both their bond and "the family of Grantchester".

"When Alphy first turns up, we [Geordie and Alphy] are sat in the pub and I say, 'What's your secret, Alphy?' And he went, 'I don't have one. I'm a strait-laced guy.'

"But all the way through, Geordie knows there's something. There's a secret and a lie that is haemorrhaging within Alphy and that comes to the surface in season 10, which has a profound effect on their relationship and really fractures that, and really fractures the family of Grantchester, as do the crimes."

Nair went on to add some key context, discussing how that is tied to Alphy's desire to find a romantic partner that he can build a life with.

"Since we last saw Alphy, he's kind of been playing the field a little bit," said Nair. "And I think what it comes down to is he finds it hard to be in a relationship. I think he is afraid of being in a relationship and settling down with one person because of things that have happened to him in his life.

"He does want to find someone, and he confides in Geordie. And then eventually he meets somebody that could potentially be that for him. But as the season progresses... he’s going through a lot, he has to face his past again and open up boxes that he thought he had dealt with and locked away.

"And so, like anybody when you're dealing with stuff like that, your relationships with the people that you know, like Geordie, are affected."
