Discovery of what they believe to be a car key near the body not only dates it to within the last 65 years, but also leads them on a trail in the hope of identifying the victim. At the end of the trail is a diary belonging to Jimmy Sullivan, a young man missing since 1976 who appears to be the victim. The final pages of the diary contain several names and addresses ; amongst them are Beth, Father Rob, Frankie C and Mr. Slater. Four seemingly unconnected people living very separate lives. It is now down to Cassie and Sunny to find out what happened to Jimmy and finally to get him home. `` Episode 2 '' Andy Wilson Chris Lang 6.41 15 October 2015 ( 2015 - 10 - 15 ) Having identified the body in the cellar as Jimmy Sullivan, the search for his murderer begins ; Cassie and Sunny investigate, starting with identifying the names featured in Jimmy 's diary. Cassie travels to Liverpool to see Maureen, Jimmy 's mother, to get a sense of who Jimmy was ; she is met by a woman who is in fact relieved that she might finally find out what happened to her son 39 years after he went missing. ' Frankie C ' is identified as Sir Phillip Cross, the government 's recently appointed entrepreneurial tzar, who denies ever having met Jimmy. ' Beth ' is identified as Lizzie Wilton, living in Croydon and married to Ray, a second - generation Jamaican man. Lizzie also denies knowing Jimmy but is clearly a very different woman from who she was in the 70s before her marriage. ' Father Rob ' is Robert Greaves who at the time of Jimmy 's death was working in the local church to Arlingham House. And ' Mr. Slater ' is Eric Slater, a wheelchair user and a retired bookkeeper living with his wife Claire in Cambridgeshire. `` Episode 3 '' Andy Wilson Chris Lang 6.29 22 October 2015 ( 2015 - 10 - 22 ) The investigation into Jimmy 's death continues. Cassie and Sunny pay a visit to Father Robert Greaves, who remembers Jimmy fondly, but is unable to help identify the mysterious ' Jo - Jo ', the person who it appears gave Jimmy the diary. Cassie and Sunny also meet Eric Slater, a former bookkeeper to Arlingham House, who remembers Jimmy well. `` Episode 4 '' Andy Wilson Chris Lang 6.61 29 October 2015 ( 2015 - 10 - 29 ) As the investigation into the cold - case murder continues, the forensic team discovers that the marks on the victim 's body are consistent with known gangland torture methods. With this in mind, Cassie and Sunny question Sir Phillip about his involvement with a prominent East End crime family 40 years ago. Did the businessman or any of the shady associates of his youth have anything to do with Jimmy 's disappearance or murder ? Meanwhile, Eric and Claire 's anniversary gets under way. Ray returns home to find Lizzie gone, broken glass where a brick was thrown through a window, and a note with the word `` Sorry '' on it. 5 `` Episode 5 '' Andy Wilson Chris Lang 5.95 5 November 2015 ( 2015 - 11 - 05 ) Following the revelation that a second victim may be buried at the bottom of the Slater 's garden, Cassie and Sunny gatecrash their 45th anniversary party and begin searching for a second body, and it 's not long before they strike gold. Eric Slater is arrested, but coherently denies all charges made against him. After some initial reluctance, Curtis agrees to help Ray go in search for Lizzie. Father Robert confesses that he was the one who stole money from the church charity fund, and that after his secret affair with JoJo, she became pregnant and he has been using the money to pay the way for his illegitimate child. Before the news breaks of Eric Slater 's arrest, Sir Phillip Cross has already struck a deal with his son 's Turkish contacts, and before he is able to change his mind, the witness who came forward with evidence against him is killed in a house fire, made to look like an accident caused when the man ' fell asleep smoking '. Evidence found in Eric Slater 's home links him to the location of the last known whereabouts of the second victim, and following the revelation that Jimmy had been selling himself for sex as a way of repaying the debt he owed to the Fenwicks, Cassie and Sunny finally realise that the connection between both murders may be Eric Slater 's hidden hatred for homosexuals. 6 `` Episode 6 '' Andy Wilson Chris Lang 6.01 12 November 2015 ( 2015 - 11 - 12 ) Father Robert 's revelations prove to have lasting repercussions, especially for Caroline when she goes into premature labour.

They are blackmailed by her birth mother 's partner, Tyler, who witnessed Colin keying the car of a homophobe.

One message appears to be an address in King 's Cross, which is soon discovered to have been a brothel at the time of Walker 's death. Cassie and Sunny interrogate Sara Mahmoud, who was known to have been working as a prostitute from the address at the time -- but she denies even knowing Walker, and claims that she was on holiday in Italy at the time of the murder. A telephone number in the victim 's diary leads Cassie and Sunny to Colin Osborne, who also denies ever having known Walker. Osborne, meanwhile, continues to feel the pressure from Tyler. Tessa Nixon 's boss, Detective Superintendent Gill ( Nathalie Armin ), asks her to take restricted duties while the investigation takes its course, which she angrily refuses to do as she has not been named as a suspect in her husband 's death. Cassie begins to suspect that her father, Martin, is hiding something from her when she discovers a train ticket in his pocket, and a series of unknown payments on her credit card. 3 ( 9 ) `` Episode 3 '' Andy Wilson Chris Lang 7.04 19 January 2017 ( 2017 - 01 - 19 ) The discovery that Walker was sexually abused during his time in primary education leads the team to suspect that the perpetrator, if still alive, would be in his early 80s. Sunny interviews Walker 's best friend, James Gregory ( Richard Hope ), who claims that in the days leading up to his death, Walker confronted the abuser, who denied being involved in any such abuse. Cassie visits the address found on the back of Walker 's business card, and interviews Marion 's mother and sister, Joy and Elise, who claim at the time of Walker 's death, Marion was the only one living at the house and could be the only person to have given out the address. Checks on Marion 's criminal history reveal she was arrested in 1988 for assaulting a police officer during a protest march, and that she was living at an address with a known IRA conspirator. Meanwhile, Sara is forced to tell her husband, Hassan, about her past life, and Colin reveals that he had a mental breakdown and was sectioned just days before Walker disappeared. 4 ( 10 ) `` Episode 4 '' Andy Wilson Chris Lang 6.52 26 January 2017 ( 2017 - 01 - 26 ) Sara 's life begins to fall apart when her son overhears details from her secret past, and inadvertently manages to tell all of his friends. Meanwhile, Cassie discovers that Colin was sacked from his City job in 1989 for reportedly sexually assaulting one of his female colleagues during an office party, a fact which leads her to believe that Colin was framed for the attack. Meanwhile, Marion is suspended from work after Zoe absconds from her parents ' care. As the investigation into Walker 's past continues, Sunny discovers that he was heavily into S&M, and sexually attacked at least one woman whom he slept with. Concerns that his private fantasies may have spilt over into his charity work are confirmed when Ellen Price, a resident at one of the care homes where Walker volunteered, comes forward to tell the police that Walker interfered with her and other children at the home. Tyler continues to blackmail Colin, leading Simon to make a drastic decision. Paul, Tessa 's second husband, fears that Jason may have inherited his father 's traits. 5 ( 11 ) `` Episode 5 '' Andy Wilson Chris Lang 6.77 2 February 2017 ( 2017 - 02 - 02 ) Sara 's long lost father turns up out of the blue with some long - buried secrets about her past. Colin is shocked to discover that the rape allegation made against him was concocted by David Walker, who paid the supposed victim £ 5,000 to fake the story. Ellen Price revisits the location where Walker and his friends used to hold ' parties ' where children were abused. Tessa 's denial of David 's activities is called into question when Ellen recalls David 's wife having turned up at one of the parties, which forced a row in front of many of the guests. As Marion 's home life continues to spiral, she tries to make things up with Zoe. Simon makes the heartbreaking decision to cease the adoption unless Colin can convince Tyler to back off. Sara 's husband uncovers evidence which confirms she was in Naples at the time of the murder. With all of the possible suspects now carrying a solid alibi, Cassie and Sunny are stumped as to who the killer might be. Sunny tries to reveal his true feelings for Cassie. 6 ( 12 ) `` Episode 6 '' Andy Wilson Chris Lang 6.77 9 February 2017 ( 2017 - 02 - 09 ) With each of the suspects having a motive, opportunity or connection to David Walker, Cassie and Sunny try to join the dots to discover who actually killed him 25 years earlier. Though Sara has provided reliable evidence that she was in Italy when the murder took place, Cassie suspects that it is too good -- that it is something put together by someone who knew that one day they would need an alibi. The team wonder whether the case is part of a wider revenge plan. On that new line of investigation, the team find that Sara and Simon had been in the same psychiatric hospital at the same time, and could have met then. The team 's notion is that each one killed the abuser of another, not their own abuser. While Sara denies every possibility put to her by Cassie, the scenes are cut with Sara 's father telling an opposite scenario of Sara 's life at age 13 to Sara 's husband. After talking to Marion 's sister and mother about the abuse suffered by Marion at the hands of her father, Cassie follows Marion to speak with her. She is in the back room of a pub, talking with Colin and Sara. In the next scene, Cassie then speaks with Colin alone, who tells her the details of the abuse in his childhood, at the hands of a friend of his parents. Cassie decides, and is supported by Sunny, that the three have suffered all their lives, all work in jobs of high value to society, there is no value in pursuing prison for them, and they have insufficient data for a solid court case, especially as one of the bodies was never found, and the other death is recorded as suicide. Each of the three, Colin, Sara and Marion, is shown telling the story of their past to their present spouse. International broadcast In the United States, the 1st series premiered on 8 April 2018 on PBS. The 2nd series premiered on 29 April 2018.
