Cassie and Sunny are assigned the case and try to identify the victim through his watch and pager. They are blackmailed by her birth mother's partner, Tyler, who witnessed Colin keying the car of a homophobe. In London, Marion Kelsey Rosie Cavaliero works as a nurse on a children's cancer ward and is struggling to balance supporting her patients, her marriage and dealing with her family.
In the Cotswolds , Jason Walker who struggles to maintain relationships with women, is visited on his birthday by his mother Tessa Nixon Lorraine Ashbourne , a detective inspector in Oxford. Sunny identifies the watch's owner as David Walker, who disappeared in May Cassie and Sunny notify Tessa, his widow, who has remarried.
As the investigation into David Walker's murder continues, the team try to decode a series of messages found on the victim's pager. 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 his credit card. 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 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.
