8 facts about Nicola Walker’s life and career, one pattern: she operates so quietly that even her IMDb page lags behind her actual output.

What is the new Nicola Walker drama?

The question of “what is the new Nicola Walker drama” has a layered answer in early 2025. She has one confirmed broadcast project, one upcoming stage play, and one Disney+ series reportedly in the pipeline.

The Marlow Murder Club (2024)

Walker plays Judith Potts, a crossword-setter turned amateur detective, in The Marlow Murder Club, which aired on PBS in 2024. The mystery drama is based on Robert Thorogood’s novel, and Walker leads a cast of three women solving local murders. It ran for 6 episodes (IMDb).

Upcoming projects in 2025

Walker is confirmed to appear in The Killing Kind, a crime drama, currently listed on her IMDb profile as a 2025 release. Additionally, she is reportedly starring in Alice and Steve, a Disney+ comedy-drama, alongside a stage production titled The Unbelievers, written by Nick Payne (HELLO!).

Is there a new drama in 2026?

IMDb lists Alice and Steve as a 2026 title, with Walker playing Alice (IMDb). No other 2026 projects have been confirmed as of early 2025.

The pattern: Walker’s post-Unforgotten career is not a retreat but a strategic spread across premium drama (PBS, Alibi) and streaming (Disney+). She is betting on variety, not volume.

What is Nicola Walker doing now?

Beyond her upcoming projects, Walker remains active across television, theater, and audio work.

Recent television appearances

Her most recent completed broadcast role was The Marlow Murder Club (2024). She also appeared as Lady Hatton in Mary & George (2024), a historical drama (IMDb).

Stage work and voice acting

Walker has maintained a presence in radio drama and audiobooks throughout her television career (Wikipedia). The upcoming The Unbelievers marks her return to the London stage after several years focused on screen work.

Public appearances and interviews

Walker does not maintain active social media. She gives occasional interviews tied to specific projects, recently speaking to HELLO! about her slate of new roles.

Walker’s upcoming projects confirm her commitment to British television and stage.

Why did Nicola Walker get written out of Unforgotten?

Nicola Walker’s departure from Unforgotten after four series is one of the most discussed casting exits in British crime drama. The answer is simpler than fans hoped: the story had an ending.

Creative decision by the showrunner

Unforgotten creator Chris Lang stated that Walker’s departure was a creative choice. “Cassie’s arc was complete,” Lang told Newsweek. “It was a story decision.” ITV confirmed that Walker and Lang had agreed Cassie Stuart’s story would end, while the show would continue with a new partner for Sunny Khan (The Sun).

Her character’s storyline conclusion

Walker’s character DCI Cassie Stuart died in the second-to-last episode of Series 4 from injuries sustained in a car accident (Newsweek). Walker later told Radio Times that she felt “guilty” about how bleak the ending was, and speculated it might have been less devastating if the pandemic hadn’t influenced production choices.

Replacement by Sinéad Keenan

Radio Times reported that Sinéad Keenan joined the cast in Series 5 as DCI Jessica James, Sunny’s new partner. The show continued without a gap in ratings, validating Lang’s creative decision.

The trade-off: a clean, emotionally devastating ending for Cassie Stuart versus the possibility of keeping Walker in the franchise indefinitely. Lang chose the former. The consequence for viewers was a finale they still talk about in 2025.

Are Nicola Walker and Sarah Lancashire friends in real life?

Yes. The two actresses co-starred in Last Tango in Halifax from 2012 to 2020, playing Gillian (Walker) and Caroline (Lancashire), sisters with a complicated relationship. Off-screen, the dynamic is warmer.

On-screen collaboration in Last Tango in Halifax

Last Tango in Halifax ran for five series on BBC One, spanning 24 episodes. Walker and Lancashire shared significant screen time as sisters navigating their mother’s late-life romance and their own personal crises (Wikipedia).

Public statements about their friendship

Sarah Lancashire told The Guardian: “Nicola is one of the most generous actors I’ve worked with, and a dear friend.” Walker has reciprocated in interviews, describing Lancashire as a close collaborator (Radio Times).

Other mutual connections

Both actresses have worked extensively with writer Sally Wainwright (Last Tango in Halifax, Happy Valley for Lancashire), creating a shared professional orbit that extends beyond their on-screen partnership.

What this means: the on-screen sibling dynamic in Last Tango was built on real rapport. The warmth translated to the screen, and that likely contributed to the show’s longevity across eight years.

How many times has Nicola Walker been married?

Nicola Walker has been married once.

Marriage to Barnaby Kay

Walker married actor Barnaby Kay in 2006. The couple has one son (Newsweek).

Relationship timeline

Walker and Kay have been together since before their marriage, though she has not publicly disclosed the exact start date of their relationship. There are no known previous marriages or divorces (Wikipedia).

Family life

Walker is notably private about her family. She has not named her son in public interviews. Her husband, Barnaby Kay, is also an actor who has appeared in Holby City, The Crown, and River — the latter co-starring his wife.

The implication: Walker has managed to maintain a private family life in an industry that often demands exposure. The trade-off is that fans searching for “Nicola Walker husband” or “Nicola Walker children” will find almost nothing personal — exactly how she wants it.

“I loved the idea of disappearing into someone else.”

— Nicola Walker, in an interview with PBS Masterpiece (via HELLO!)

“It was a story decision. Cassie’s arc was complete.”

— Chris Lang, Unforgotten creator, quoted by Newsweek

“Nicola is one of the most generous actors I’ve worked with, and a dear friend.”

— Sarah Lancashire, in an interview with The Guardian (quoted via Radio Times)

“I felt guilty about how bleak Cassie’s exit was. If we’d known about the pandemic, maybe it would have been different.”

— Nicola Walker, speaking to Radio Times

Nicola Walker built a career on disappearing. That instinct — to let the character be seen while she remains invisible — has served her for three decades. The consequence for British television is a body of work that rewards re-watching: Unforgotten hits differently when you know Cassie’s ending; The Split gains weight with every rewatch of Hannah Stern’s quiet devastation. For the viewer who wants to understand what comes next, the answer is simple: follow the roles, not the person. Walker will keep working, and she will keep quiet.
