Beyond Paradise makes its return for a fresh series on Friday evening and enthusiasts will be thrilled.

Series four episode one features Detective Inspector for Shipton Abbott Police Station, Humphrey Goodman, portrayed by Kris Marshall, investigating a crime novelist's death that uncannily reflects the details of his final novel. Humphrey must determine whether it was a coincidence or murder by design...

Meanwhile, The Lily Bond is caught adrift leaving Humphrey and Martha Lloyd, portrayed by Sally Bretton, back home with Martha's mother Anne Lloyd, portrayed by Barbara Flynn.

Nevertheless, things won't be straightforward for the couple in series four as Martha star Sally, 45, hinted that the pair will encounter "unexpected hurdles".

Speaking ahead of series four, Sally said: "They have so much fun in this series, but as always, there are unexpected hurdles.

"They've taken on a huge house project that is stunning but comes with plenty of problems, and Martha is constantly juggling her business, the builder, the new home, and Humphrey."

Meanwhile, Humphrey star Kris, 52, teased of his character and series four: "He's finally a married man!

"They've put fostering on the back burner to focus on their new house project, which, as you can imagine with Humphrey's clumsiness, is a recipe for disaster. He's not at all gifted in the DIY department, causing more issues than he solves."

Discussing Humphrey being compelled to leave behind his cherished houseboat this series, Kris noted: "Ever since we met Humphrey in the Caribbean, he's been a frustrated sailor.

"He loves the romanticism of being on a boat and is always drawn to the water, so he is sad that this chapter of his life has closed. However, their new house is in the perfect location, and hopefully there will be more boats in his future."

Meanwhile, a synopsis for series four hints: "DI Humphrey Goodman and the Shipton Abbott team are back, facing a fresh wave of mind-boggling puzzles. From the suspicious death of a crime novelist, whose final plot eerily mirrors their demise, to an intruder who returns to undo the crime scene they created, the team have their work cut out for them.

"Set against the breathtaking landscapes of Devon and Cornwall, fact and folklore blur when a witness claims a mermaid wrecked a local seaweed farm, an off-grid community fight developers with the image of the Green Man, a Morris dancer is targeted in plain sight, and a stolen pirate map reappears under mysterious circumstances.

"Beyond the station, Humphrey and Martha launch into married life as they search for a new place to call home, all whilst Humphrey faces mounting pressure when tasked with an impossible decision that will change his team forever.

"Meanwhile, Anne rises to new heights as a local councillor, Esther is forced to grapple with the consequences of her past choices, and Zoe starts planning her next steps. Elsewhere, Kelby's dating life takes an unexpected turn when he meets someone online, but Margo spots warning signs that all may not be as it seems..."

Beyond Paradise returns this Friday at 8pm on BBC One and BBC iPlayer.
