The hit thriller Unforgotten returns to ITV at 9 p.m. on Monday, February 22nd to watch the fourth series. Cassie and Sunny are back on site to solve more cold cases.
If you haven’t been watching the show or need a quick refresher, here’s a rundown of what went on in the last three series, each focusing on a different murder case.
*** Warning: big spoilers ahead ***
Who is playing the main role? Unforgotten and what is it about?
Unforgotten This is followed by two refreshingly real London detectives: DCI Cassie Stuart (Nicola Walker) and DI Sunil “Sunny” Khan (Sanjeev Bhaskar), who solve decades of unsolved murders.
The show, which debuted in 2015, was written by Chris Lang, who also wrote Dark heart and The connection diagram.
Cassie and Sunny are not your typical TV detectives. Lang calls them “extraordinary in their ordinaryness”. The drama centers around the murder cases rather than any personality traits the couple might have, and their relationship is platonic.
The only background info about the characters you need to know is that after her mother dies, Cassie lives with her father Martin (Peter Egan) and has two sons who are studying at university. Sunny is a single parent and has two teenage daughters following his divorce from his wife.
Cassie and Sunny are called into the basement of a destroyed house where a skeleton has been found. Her only clue as to who it might be is a set of car keys found near the remains.
It leads them to a car where they find a diary in the trunk. The diary, inscribed as a gift from someone named JoJo, belongs to Jimmy Sullivan (Harley Alexander-Sule), a Liverpool teenager who went missing in 1976. It soon confirmed the remains were his, but who killed him?
At home, Cassie is concerned after her father shows her a box of letters he found after her mother died that shows she was having an affair. But she tries to put her feelings aside while working on the case.
Cassie and Sunny’s team follows up contacts in Jimmy’s diary: Among them are four suspects, including Eric Slater (Tom Courtenay), a former accountant at Jimmy’s hostel.
Another is Frankie C, also known as Sir Philip Cross (Trevor Eve). He was recently named the government’s entrepreneurial tsar, but has a shady past as a mob enforcer for an East End gang. He tortured people who owed the gang money. We discover that Jimmy had borrowed £ 50 from the gang to help his friend JoJo with an abortion.
The third suspect is Lizzie, a woman who stole Jimmy JoJo’s abortion money. Lizzie, who has a racist past, is now helping disadvantaged young people locally with her Jamaican soccer coach husband.
The fourth is a pastor named Father Rob, who was the chaplain at the inn where Jimmy was staying. It turns out that JoJo, who is believed to be Jimmy’s girlfriend, became pregnant with Father Rob’s baby at age 15. He stole parish funds to support her and the child. The question arises: did Jimmy have a violent confrontation with Father Rob that could have resulted in the death of the teenager?
Cassie and Sunny drop everyone except Eric, who has been convicted of a homophobic attack in the past. While Jimmy wasn’t gay, he’d been a sex worker, and the detectives decide to investigate further.
All hell breaks loose when, following a tip-off from his son, the corpse of a gay man is found in Eric’s garden and Eric is charged with both murders.
But Cassie doesn’t think Eric is guilty and she’s quite right. The real killer is Eric’s wife Claire.
Eric admits to police that he is a withdrawn gay man and that his jealous wife, who suffers from postnatal psychosis, murdered his male lovers when she caught them having sex.
Eric buried both bodies to avoid arrest.
The gruesome remains of a Tory party fundraiser and club promoter David Walker (Daniel Gosling), who disappeared in 1989, are in a suitcase in the River Lea. Cassie and Sunny identify the body by tracking repairs to David’s eye-catching watch.
The couple hit on several suspects, including David’s widow DI Tessa Nixon (Lorraine Ashboure), a passionate Oxford copper woman who remarried. She has a step daughter and a 30 year old son named Jason.
Another suspect is Brighton-based attorney Colin Osbourne (Mark Bonnar), who with his husband Simon adopts a six-year-old girl and is blackmailed by her birth mother. He has no obvious connection with the victim, but he clearly has anger issues.
The third suspect is pediatric nurse Marion Kelsey (Rosie Cavaliero). Her husband Tony is concerned about her sanity.
And the fourth is a school teacher, Sara Mahmoud (Badira Timini), who admits that David may have been one of her clients when she worked as a sex worker in a brothel long ago.
When the detectives find out that David was sexually abused as a child, they mistakenly think that he died before his perpetrator.
Cassie’s father and Sunny are both trying to get online with little success. Cassie finds out that her father went to Winchester to find the man who had an affair with her mother. It closes when the man sends him a letter proving that she has ended the affair. Sunny picks up a rash kiss with Cassie that is quickly rejected, and they agree to keep things platonic.
When links are discovered between attorney Colin, who donated to the Tory Party in the 1980s, and David, the mystery begins to be solved. Colin quit his banking job and broke down after David tricked an employee into falsely accusing Colin of rape. Obviously David wanted Colin out of the picture because he was getting too curious. Colin was led to believe he had raped the woman during an alcohol bout, but in fact she was paid £ 5,000 to get him drunk.
It soon becomes clear that David was a pedophile who used his connections with children’s charities to attack his victims. We discover that as a young teenager, Sara, the school teacher, was raped by David at parties where he drugged children at risk.
Cassie finds out that Sara, the nurse Marion, and the lawyer Colin know each other and are victims of child sexual abuse. They met in a mental health department and struck a deal to get revenge on each other’s child abusers.
Marion killed Sara’s perpetrator David; Sara killed Colin’s perpetrator Len Paxton; and Colin killed Marion’s culprit, her father.
Cassie wants to save them jail; You have suffered so much. Sunny supports them. You close an eye and don’t press charges.
Cassie and Sunny search for the serial killer and rapist responsible for the murder of the schoolgirl Hayley Reid (Bronagh Waugh), who disappeared from a coastal town on New Years Day in 1999. Her remains were discovered by workers in London when they were repairing parts of the M1 motorway in London.
Four friends who rent a vacation home and the site of Hayley’s murder at the same time become suspects.
One is the host of the TV quiz show Jamie Hollis (Kevin McNally). It turns out he believes his worried son Elliott killed her in a drink-driving accident. something he’s been covering up for 18 years.
Another is houseguest Chris Lowe (James Fleet), a struggling artist who lives out of a van with his dog. His daughter tells Sunny about his child porn charge, which was later dropped by police when she was paid on his stolen credit card.
The third is insurance agent Pete Carr (Neil Morrissey). He spent time in a Hong Kong prison for defrauding a charity and admitted to a robbery at a Middenham church the night Hayley was murdered nearby.
He is stabbed to death when his past is revealed after Cassie accidentally left his files at a coffee shop. When he dies, Cassie’s job is at stake.
The final suspect is the beloved GP Dr. Tim Finch (Alex Jennings). He has been investigated for abusing an elderly patient, but nothing initially suggests he is the evil killer.
Until a speeding ticket shows the GP racing out of Middenham on January 3, 2000 on his way to London. This lead leads to his arrest on suspicion of Hayley’s murder.
A hair tie, necklace and underwear are found during a search of his home. He says they were bought for his daughters at a party, but DNA results show they belonged to Alison Baldwin, a 14-year-old from Cambridge who was raped and strangled in 1997. He later gives a terrifying confession for Hayley’s murder.
The revelation that Finch is a cold psychopath affects Cassie greatly, and she takes a sabbatical year to recover and give her romance with DCI Bentley (Alastair MacKenzie) a good try.
The series ends with Cassie and Sunny bringing flowers to Hayley’s final resting place in a memorial garden.
And now for the fourth series …
Filming for the latest series resumed in September 2020 after an interruption due to the Covid pandemic.
In the new episodes, Cassie is upset when her plans to retire from the police force for “her own health and well-being” are foiled as her father’s dementia worsens.
She learns that she will not be eligible for her full pension unless she has completed her 30 years of service.
Cassie is gutted but decides to return to work and join Sunny, who is investigating the case of a headless corpse dumped in a junkyard in north London. It’s frozen stone – has it been stored in a household freezer for decades?
And who is the culprit of the recent murder? You have to wait and see.
