What is Shetland Series 11 about?

The new six-part series centres on a historic murder that will forever change the lives of those connected to it in the present day.

When a car is dredged from the water, the investigation team makes a grim discovery: skeletal remains belonging to an unidentified male are found in the boot.

The vehicle belongs to Dr Raymond Linden, a respected local GP who fled the Shetland Isles nine years earlier.

His disappearance has remained something of a mystery, but the discovery of the car and its horrifying contents gives DI Calder and DI Tosh a fresh trail to follow.

The detectives must establish the identity of the victim, locate the missing doctor and uncover exactly what happened in the years leading up to his disappearance.

As secrets emerge from the watery grave, the investigation begins to send shockwaves through the local community and beyond.

However, finding out what happened to Raymond Linden is far from straightforward. Those who knew him offer very different accounts of his character, his relationships and the circumstances surrounding his departure from the islands.

Calder and Tosh soon discover that the truth is considerably darker than anyone initially imagined.

Who is in the cast of Shetland Series 11?

The new series features a mixture of familiar faces and exciting guest performers, with the central investigation bringing several new characters into the detectives’ orbit.

Ashley Jensen as DI Ruth Calder

Ashley Jensen returns as DI Ruth Calder, who has led the series since its eighth instalment following Douglas Henshall’s departure.

Calder is an experienced detective with a complicated past and a sometimes guarded approach to her personal relationships.

Since arriving in Shetland, she has developed a strong working partnership with Tosh, although their different approaches to policing occasionally create challenges.

The previous series saw Ruth confront aspects of her past, including her family’s connection to religion. In the new episodes, viewers will see another side of the detective as she attempts to find a better balance between her professional and personal life.

Alison O’Donnell as DI Alison ‘Tosh’ McIntosh

Alison O’Donnell returns as Tosh, continuing her role as one of the series’ central characters.

Tosh is an intelligent, determined detective whose knowledge of the islands and their community makes her an invaluable part of the investigation team.

Her partnership with Calder has become one of the defining features of the newer series, with the two detectives developing a mutual understanding despite their contrasting personalities.

The new murder investigation will test their investigative instincts as they attempt to unravel the complicated history surrounding Raymond Linden.

Stella Gonet as Martha Linden

Stella Gonet joins the guest cast as Martha Linden, the formidable mother of missing doctor Raymond.

When Calder and Tosh meet her, Martha is convinced that something terrible happened to her son and believes this was what forced him to leave Shetland nine years earlier.

Her determination to understand what happened to Raymond could prove significant as the detectives begin piecing together his final days on the islands.

Gonet is an accomplished television and theatre actress, known for appearances in productions including The House of Eliott, Holby City and The Crown.

John Wark as Eric Linden

John Wark plays Eric Linden, Raymond’s brother.

Unlike their mother, Eric is not entirely convinced that something sinister happened to Raymond, immediately introducing another perspective into the investigation.

The differences between the family’s recollections could prove crucial as Calder and Tosh attempt to establish what kind of man the missing doctor really was.

Christine Bottomley as Emily

Christine Bottomley appears as Emily, Raymond’s ex-wife.

Her account of their marriage is very different from the version presented by his family.

Rather than remembering Raymond as a respected doctor who was forced to abandon his home, Emily describes a troubled man whose behaviour made life extremely difficult for her and their son, Jonah.

She reveals that Raymond made both their lives a living hell, giving the detectives a much darker understanding of his personality and domestic circumstances.

Jude Bain as Jonah

Jude Bain plays Jonah, Raymond and Emily’s son.

As the investigation develops, the detectives must consider the impact of Raymond’s disappearance on those closest to him, including the family he left behind.

Jonah’s experiences could help shed further light on the missing doctor’s behaviour and the events that led to his departure.

Gregor Fisher as Donald Pierce

Gregor Fisher joins the series as Donald Pierce, a lonely and overzealous older man who becomes unexpectedly caught up in the investigation.

His involvement begins through an encounter with Sandy, but his connection to the unfolding events could prove more significant than initially expected.

Fisher will be familiar to television audiences for his long-running role as Rab C Nesbitt in the popular Scottish comedy series of the same name, as well as appearances in Love Actually and The Weavers.

What happens to Ruth Calder in the new series?

Away from the central murder investigation, the new series will also explore Calder’s personal life and her complicated relationship with her family.

Last time around, viewers watched Ruth confront elements of her past and come to terms with her family’s connection to religion.

In Series 11, she finds herself sharing her home with an unexpected house guest: her brother Alan.

Alan has moved in while work is being carried out on the manse, and although Ruth initially pretends to be irritated by the arrangement, she is secretly beginning to enjoy having him around.

He cooks wonderful dinners and looks after her, despite being her younger brother.

For someone who has often kept her personal life at arm’s length, having Alan around provides Ruth with an opportunity to enjoy a different kind of domestic routine.

However, the apparent harmony between the siblings is not destined to last.

As the investigation develops, Calder is forced to confront her own behaviour towards the people she loves most.

The case will make her question whether she has allowed her emotional barriers to damage her closest relationships and whether she can finally let those walls down before it is too late.

It promises to be an important personal storyline for the detective, adding another emotional dimension to the new series.

What has Ashley Jensen said about the new series?

Ashley Jensen has spoken about where viewers will find Ruth Calder when the new episodes begin, suggesting that the detective is in a relatively positive place in her life.

Speaking about this series, Ashley Jensen said:

“We find her in quite a happy place. She’s settled, and she’s got her brother Alan staying with her. She pretends to be annoyed about it, but I think she’s secretly delighted he’s there. He cooks wonderful dinners and looks after her, even though he’s the wee brother.

At work, she’s comfortable. She knows what she’s doing and has a good relationship with Tosh. They work differently, but there’s a mutual respect and they complement each other. They’ve got a good cop, bad cop approach that works really well”.

Her comments suggest that the relationship between Calder and Tosh remains central to the new series, with their contrasting personalities continuing to provide an effective balance.

However, the murder investigation may prove particularly challenging as the detectives are forced to navigate a complicated web of family relationships, conflicting memories and deeply buried secrets.

The history of Shetland: From Ann Cleeves’ novels to BBC success

Shetland first arrived on BBC One in 2013 and quickly established itself as one of Britain’s most popular crime dramas.

The series was originally based on the novels of acclaimed crime writer Ann Cleeves, whose atmospheric stories introduced readers to the fictional and real-world communities of the Shetland Islands.

The television adaptation was developed by writer David Kane, who helped bring Cleeves’ characters and distinctive storytelling style to the screen.

The original series starred Douglas Henshall as DI Jimmy Pérez, a thoughtful and determined detective whose investigations often exposed the complex relationships and hidden tensions within the island community.

Henshall became closely associated with the programme, leading the drama for its first seven series and helping establish its reputation as a distinctive addition to the BBC crime drama landscape.

His departure marked the end of an era, but the programme successfully reinvented itself with the introduction of Ashley Jensen as DI Ruth Calder in Series 8.

The transition brought a new dynamic to the show while retaining the elements audiences had come to love: atmospheric locations, intricate mysteries, compelling characters and investigations rooted in the lives of the Shetland community.

Alison O’Donnell’s Tosh remained a vital part of the programme, helping provide continuity between the Pérez and Calder eras.

The series has continued to attract viewers thanks to its combination of traditional detective storytelling and emotionally complex character drama.

Its stunning coastal scenery has also become one of its most recognisable features, with the islands providing a striking backdrop to stories that frequently explore isolation, family loyalties, community tensions and the consequences of secrets kept for years.

Although the central mysteries change from series to series, the show’s ability to balance suspense with character development remains a major part of its appeal.

How many episodes are in Shetland Series 11?

The latest series consists of six episodes, with the historic murder investigation providing the central storyline throughout.

Viewers can expect the mystery to develop gradually as Calder and Tosh investigate the identity of the skeletal remains, track down Raymond Linden and question those who knew him.

The conflicting accounts of the doctor’s character and disappearance will become increasingly important as the detectives attempt to establish what really happened nine years earlier.

Alongside the investigation, the series will continue exploring Ruth’s personal development and her relationship with Alan.

The six-part format gives the writers room to develop both strands, combining an unfolding criminal investigation with the emotional stories of the characters at its heart.

When does Shetland Series 11 start on BBC One?

Shetland Series 11 begins tonight at 9pm on BBC One.

The new episodes will also be available to watch on BBC iPlayer, giving viewers the opportunity to catch up or watch at a time that suits them.

With a disturbing discovery, a missing doctor, conflicting family accounts and a murder mystery stretching back almost a decade, the new series looks set to deliver another compelling chapter in the BBC drama’s long-running story.

And as Ruth Calder finds herself confronting difficult questions about her own relationships, the investigation could prove just as revealing for the detective as it is for the people she is questioning.

Shetland Series 11 starts tonight at 9pm on BBC One and BBC iPlayer.
