ITV drama Unforgotten has returned for a fourth season, with a brand new cold murder case for the team to solve.

Nicola Walker and Sanjeev Bhaskar lead the cast, once again reprising their roles as cold case cops DCI Cassie Stewart and DI Sunny Khan.

As with previous seasons, the line-up of potential Unforgotten suspects is typically star-studded, with the likes of Dame Sheila Hancock and Life on Mars star Liz White joining the cast for season four, according to Radio Times.

Season four begins with the discovery of a body dumped at a London scrapyard, and our detectives learn that the remains (which had been hidden, frozen, inside a freezer) belong to an individual who’s been missing since the 1990s.

Read on for our guide to the cast and characters of Unforgotten seasons one through to four.

Unforgotten series 4: Cast

Nicola Walker plays DCI Cassie Stewart

Who is DCI Cassie Stewart? Forget maverick cops – lead character Cassie Stewart is a professional, level-headed murder detective devoted to solving cold cases and bringing the killers to justice for the victims’ families. A widow, she has two grown-up sons. She also has an excellent working relationship with her sidekick Sunny.

However, season four kicks off with a rocky start for Cassie: following a nervous breakdown, she unsuccessfully requests to retire three months early from the police force, just shy of her 30 year anniversary.

Where have I seen Nicola Walker before? You may have recently watched Nicola Walker play Jane Oliver in Collateral, or Hannah Sterne in The Split, or Gillian in Last Tango in Halifax, or perhaps you remember her as Ruth Evershed in Spooks? Other credits have included River, Babylon, Inside Men, and Torn.

Sanjeev Bhaskar plays DI Sunny Khan

Who is DI Sunny Khan? Sunny is Cassie’s second-in-command. He is also dedicated to his job, working hard to solve long-ago murders with empathy and intelligence – despite being an overworked single father of two exasperating teenage girls.

At the beginning of season four, Sunny is under even more pressure – with Cassie absent, it’s him who initially takes the lead in the new cold case investigation. (Hopefully Sunny’s famous backpack will spur him on.)

Where have I seen Sanjeev Bhaskar before? Sanjeev Bhaskar is best known for his comedy work, starring in the sitcom The Kumars at No 42 and appearing in the BBC sketch comedy series Goodness Gracious Me. You may have spotted him in Paddington 2 (as Dr Jafri) and The Indian Doctor (as Dr Prem Sharma), and in the Beatles film Yesterday (as Jed Malik). He is set to play the role Cain in the upcoming Neil Gaiman adaptation The Sandman.

The actor has led the cast of Unforgotten alongside Nicola Walker since day one.

Peter Egan plays Martin Hughes

Who is Martin Hughes? Cassie’s dad, whom she previously lived with. He is a widower but is now in a long-term relationship with a new woman, a previous point of tension between him and Cassie. In season four he also has early-onset dementia, which results in him developing depression and alienating Cassie.

Where have I seen Peter Egan before? A veteran actor, his credits include Hold the Sunset, Downton Abbey (as Hugh “Shrimpie” MacClare), Home Again, Big Breadwinner Hog, Prince Regent, and Ever Decreasing Circles. He’s recently starred in Netflix’s After Life season two, alongside Ricky Gervais.

Alastair MacKenzie plays DCI John Bentley

Who is DCI John Bentley? An officer on the original case in season three. He helped with the new investigation and developed an interest in Cassie, before later establishing a relationship with her. At the start of season four, it looks like the pair are fully committed.

Where have I seen Alastair MacKenzie before? The actor recently played Guy Riverty in Deep Water, and Jamie in the Cold Feet reboot, and Craig Petrie in ITV’s The Loch. He appeared as William Brereton in Tudor drama Wolf Hall, and played Lord Rothcroft in Dracula, but is perhaps best known for starring as young laird Archie MacDonald in Monarch of the Glen.

Jassa Ahluwalia plays Adam

Who is Adam? Cassie’s son, who has yet to find a job.

Where have I seen Jassa Ahluwalia before? Known for his role on Unforgotten, he also played Dimitri in Peaky Blinders, and Rocky in Some Girls. Other past projects include Ripper Street (as Vincent Featherwell), and the film The Whale.

Who is Fiona Grayson? A therapist who lives in the Peak District with her husband and two children.

Where have I seen Liz White before? She’s best known for playing Annie Cartwright in the BBC time-slip series Life on Mars, and as Emma Keane in the Channel 4 drama series Ackley Bridge.

Susan Lynch plays Elizabeth Baildon

Who is Elizabeth Baildon? A high-flying career woman who lives in Cambridge.

Where have I seen Susan Lynch before? She has starred in the likes of National Treasure, Sex Education, Doctor Who, Apple Tree Yard, the Downton Abbey film, and 16 Years of Alcohol.

Sheila Hancock plays Eileen

Who is Eileen? Elizabeth’s cantankerous and bed-bound mother.

Where have I seen Dame Sheila Hancock before? The acting legend is known for a long career on the stage on both sides of the Atlantic, but she’s also starred in recent projects like Endeavour, A Discovery of Witches, The Boy in the Striped Pyjamas, and Delcious.

Andy Nyman plays Dean Barton

Who is Dean Barton? A seemingly legitimate businessman, he’s happily married with a disabled adult son.

Where have I seen Andy Nyman before? He recently played Dan in the film Judy, and has starred in Hanna, Wanderlust, Ghost Stories, and Peaky Blinders (as Winston Churchill).

Phaldut Sharma plays Ram Sidhu

Who is Ram Sidhu? An expectant father in Southall.

UK for FREE

Unforgotten returns for its fourth season on ITV, and anyone with Freeview, satellite, or a cable subscription can watch it every week from Monday, 22 February at 9 pm GMT, until the conclusion on March 29.

Episodes are also available to watch live via ITV Hub – the network’s completely FREE online service – or on-demand after each episode’s initial broadcast. The platform is full of high-quality drama, including Quiz, Broadchurch, and the David Tennant-starring Des – but you should hold a valid TV license, said TechRadar.

It’s an ITV exclusive, so if you’re out of the country, you won’t be able to tune in unless you download a Virtual Private Network or VPN. We explain how you can do this below.

Outside the UK

While fans of crime dramas in the UK can enjoy Unforgotten season 4 online with ease, regional restrictions mean that tuning in from anywhere else in the world will be near impossible. That means that anyone from the UK who's currently abroad – and has paid for an annual TV license – won’t be able to connect to ITV Hub either.

Luckily, downloading a VPN provides a simple solution. This nifty bit of kit changes your IP address, allowing you to connect to your favorite on-demand services and watch all its premium content regardless of where you’re streaming from.
