Beyond Paradise stars Kris Marshall and Sally Bretton, who play husband and wife Humphrey Goodman and Martha Lloyd, have opened up about how the couple faces some changes in the new series.

After having to move back in with Martha's mother, Anne (Barbara Flynn), and Humphrey being forced to let go of one of his colleagues from the police station, it's not plain sailing for the beloved couple.

When speaking about living on a boat and married life, Sally said exclusively to Express.co.uk, "Martha starts reflecting on, 'Was this a bit of an unexpected twist anyway? Going to live on the boat as it wasn't really the plan originally'.

"And maybe now that they're married and they want to focus a lot on settling a little bit more, and maybe it's time to start having a look at a house, and I think they want to focus on each other and have all of the fun and everything that they always have done, but they've been knocked off center a lot."

Kris went on, "I think it's being thrust into making a decision about moving forward. You know, and the fact that it comes right at the beginning of episode one.

"In the last episode, we saw them get married. They sort of reaffirmed their commitment to each other as a couple, despite everything else that's happened to them during the fostering journey, living on a boat, and living with her mum. You know, all the other outward factors that influence them, they're always just the two of them together.

"They come back to this sort of like a solid base, and then to have the sort of almost immediate need to change their life again as soon as they've been married.

"Humphrey's very much like, 'I go off and solve some puzzles, solve some murders, solve some crimes, perfect, and then come back live on my boat'. He would never change. He wouldn't change a thing, you know, he wouldn't even think about it. He doesn't think of life progression or anything like that."

"So it needs something to thrust that basically from his happy existence into that," he added.

After his new boss told him that Humphrey needs to fire one of his colleagues, Kris explained that the detective doesn't like the pressure he is under and buries his head in the sand.

"He hates any kind of authority, he hates rules, he hates being told what he has to do, and so it's thrust upon him, and it literally comes knocking on his door as it does. You know, he really detests that, really dislikes it, and he doesn't like the pressure," the actor shared.

"And also, he loves his team. He feels like losing one of them would be like losing an appendage, or a part of him, you know.

"He doesn't feel like he's the boss. He feels that they all bring a sort of an equal amount to the Melange, you know, to the Jamboree, and so I think he's thrust into this, as I said about him, living on a boat, he's quite happy living on a boat.

"It's not that he doesn't think about Martha, it's just not on his radar. He's this slightly neurodiverse kind of guy, and so these things are thrust upon him, and he doesn't necessarily deal with it very well."
