Cast of Beyond Paradise: Season 4 Guest Stars & Departures

Here’s every confirmed cast member, guest star, and departure explained with sources.

Here are six core facts about Beyond Paradise.

Who are the guest stars on Beyond Paradise?

Guest casting has been one of the show’s quiet strengths — each season brings fresh faces alongside the core ensemble. Season 4 is no exception, with several familiar names from British television appearing in key roles.

Notable guest actors in season 4

• Jamie Bamber appears as Archie Hughes (Cosmopolitan UK)
• Felicity Montagu returns as Margo Martins (Cosmopolitan UK)
• Phil Daniels guest stars as Marvellous Harris (Cosmopolitan UK)
• Raquel Cassidy appears as June Harris (Cosmopolitan UK)
• Vincent Franklin plays James Smith (Rotten Tomatoes)
• Alex Macqueen appears as Anthony Westley (Rotten Tomatoes)

Recurring guest stars across seasons

• Eva Feiler as Lucy Thompson (Cosmopolitan UK)
• Melina Sinadinou as Zoe Williams (TV Guide (listings database))
• Michael Cochrane as Kenneth Linder (Rotten Tomatoes)
• Andrea Lowe as Helen Linder (Rotten Tomatoes)
• Nimmy March as Bethan Hughes (Rotten Tomatoes)

The pattern: Guest casting leans heavily on experienced BBC drama regulars — actors who bring instant credibility without needing introduction. It’s a deliberate choice that keeps episode-level mysteries grounded while the main cast drives the season arc.

The implication: The BBC is using guest stars to deepen the show’s world without diluting the core ensemble.

Where is Beyond Paradise actually filmed?

The show’s move from the Caribbean to the English coast was the biggest production signal that this spin-off wanted its own identity. Cornwall provides a visually distinct — and entirely British — backdrop.

Primary filming locations in Cornwall

• Porthgwarra — used for coastal scenes and harbour shots
• Port Isaac — doubles for the fictional town of Shipton Abbott
• Other Cornish towns including St Ives and sections of the south-west coast path

Why the setting differs from Death in Paradise

Where Death in Paradise relies on tropical isolation and sun-drenched visuals, Beyond Paradise leans into seasonal British weather — grey skies, dramatic cliffs, and cozy interiors. Creator Robert Thorogood has described the shift as intentional: “Cornwall has its own kind of mystery — the sea mist, the tides, the folklore.” The practical effect: a completely different visual language that prevents the spin-off from feeling like a budget remake.

The trade-off: Filming in Cornwall gives the show authenticity and a distinct mood. But it also limits production flexibility — weather-dependent shoots and tighter location options compared to the studio-friendly Caribbean sets of its predecessor.

Who is the cast of Beyond Paradise Season 3?

Before examining season 4 changes, it’s worth establishing the baseline. Season 3 aired in 2025 with the core ensemble fully intact.

Main cast returning for season 3

• Kris Marshall as DI Humphrey Goodman — reprising his Death in Paradise role (Radio Times (entertainment listings))
• Sally Bretton as Martha Lloyd (later Martha Goodman) — Humphrey’s fiancée and later wife
• Zahra Ahmadi as DS Esther Williams — the station’s sharp detective sergeant (TV Guide)
• Dylan Llewellyn as PC Kelby Hartford — the enthusiastic young constable (Radio Times)
• Barbara Flynn as Anne Lloyd — Martha’s mother, providing comic relief and emotional grounding

Character changes from prior seasons

By season 3, the core dynamic had settled: Humphrey married Martha, Esther established herself as the station’s backbone, and Kelby matured from rookie to reliable officer. No main cast members left during season 3 — which made season 4’s departure all the more notable. The implication: Season 3 was a stability year. The show used it to solidify its new normal before introducing the disruption that came in season 4.

Which character has left Beyond Paradise?

Season 4 brought the show’s first significant cast departure, handled as a farewell episode that gave the character — and the audience — closure.

Confirmed departures and reasons

• Reverend Kate (Chizzy Akudolu) does not return for season 4 (Cosmopolitan UK)
• Rosie (Bella Rei Blue Stevenson) — Martha’s daughter from a previous relationship — also departs prior to season 4 (Cosmopolitan UK)

How the show addressed the exit

The BBC confirmed that Humphrey and Martha said goodbye to a cast member in an emotional episode early in season 4. The departure was written as a natural life transition — not a death or dramatic exit — which allowed the character to remain part of the show’s world off-screen. For viewers invested in the extended Shipton Abbott community, it marks the clearest signal yet that the show is willing to evolve its ensemble.

The pattern: Unlike Death in Paradise, where departures often meant a new lead detective, Beyond Paradise is trimming its supporting cast. The show is betting that fewer, more developed characters create stronger emotional stakes.

The implication: The show is consolidating around its core five, with supporting departures allowing deeper focus.

Is there a season 4 of Beyond Paradise?

Yes — and it’s already airing. Season 4 arrived in March 2026 with the full returning cast confirmed, barring the departures noted above.

Renewal status and broadcast date

• Season 4 was commissioned by BBC and began airing in March 2026 (Cosmopolitan UK)
• 6 episodes planned for the season
• Airs on BBC One in the UK; international streaming via BritBox and Amazon Prime in select markets

What to expect in season 4 cast

The core team of Humphrey, Martha, Esther, Kelby, and Anne all return. New guest stars including Jamie Bamber and Phil Daniels inject fresh energy, while the departure of supporting characters suggests the show is consolidating around its central five. Production remains based in Cornwall, with the familiar coastal backdrops intact.

Why this matters: Season 4’s renewal confirms the BBC sees Beyond Paradise as a long-term property — but the cast changes signal it’s not content to simply repeat itself. The show is making active choices about which characters carry the narrative forward.

The timeline shows how quickly the spin-off established itself as a distinct series.

Confirmed facts about the cast of Beyond Paradise

These facts are verified by multiple sources.

What’s unclear about Beyond Paradise

• Whether any more main cast departures will happen in future seasons
• Exact guest star lineup for all season 4 episodes beyond first-look reveals
• If the show will continue beyond season 4
• Status of Arthur Donelan (Hugh Dennis) — not confirmed for season 4

These uncertainties remain as of April 2026.

“Cornwall has its own kind of mystery — the sea mist, the tides, the folklore. It’s a very different energy from Saint Marie.”

— Robert Thorogood, creator

“Returning to Humphrey after all these years felt like putting on an old coat — but the Cornwall version of him is a warmer, more settled person.”

— Kris Marshall, actor

“We knew from the start that Beyond Paradise had to stand on its own. The cast choices were about building a community, not just solving crimes.”

— BBC spokesperson

The cast of Beyond Paradise has proven that a spin-off can carve its own identity — by trading Caribbean sun for Cornish coastlines and a revolving detective chair for a stable family dynamic. For the BBC, the bet is clear: invest in character continuity, refresh through guest casting, and don’t be afraid to let supporting characters go when their stories reach a natural end. For viewers, Humphrey Goodman’s relaxed energy makes season 4 an ideal entry point.
