Cassie travels up to Liverpool to visit Jimmy’s Irish mother, Maureen Sullivan. After that, he visits a payphone and leaves a voicemail message for a woman called Jojo. Unfortunately, Tyler, the partner of Flo’s birth mother, has been following Colin and sees this misdemeanor. She remembers Beth and her bovver-boy lover, Vincent Erskine, quite well. I know what you are. 39 years after he dies, Maureen Sullivan finally visits the place where her son Jimmy's body was found. Sir Philip doesn’t suffer fools, or indeed anyone, gladly – even if they happen to be his son. She remarried eight years ago; her husband Paul has his own child, a teenaged daughter. Once again, the photo produces a quick flashback and an even quicker denial. Two workers pull the moldering object from the dredge, discerning a zippered suitcase. Colin’s husband does allude to old problems with “temper issues.” The couple is in the final stages of adopting a young girl, Flo. Photo: John Rogers/Mainstreet Pictures. The detectives eventually puzzle out that one message is an address in King’s Cross for what used to be a flat. It’s not Poirot but it’s a compelling j’accuse thrown at her husband by Claire.

She’s interviewing to become principal of a school for troubled children, and her contention that she understands the school’s kids because she used to be just like them gets her a second interview. By matching up payment records to the dates and then cross-checking that with missing person reports, they discover their skeleton’s identity: David Walker, last seen May 8, 1990. Expect to hear more on this. With the cops discovering Eric’s past as a bookkeeper at Arlingham House, there’s more to be uncovered soon.
Let’s assume it’s the Jojo from Jimmy’s diary and wonder once again: what did Robert do? Read our recaps of the previous season’s finale and the next episode in this season. There’s excellent, quietly powerful work from Frances Tomelty in these scenes – solid weight behind Cassie’s belief that as long as there’s someone around affected by it, murder stays murder. And just like the others, he remembers Jimmy, too. Robert, Lizzie and Eric seem fundamentally decent sorts, probably guilty of cowardice, keeping quiet or some other sins of omission. Of course it’s the dementia talking, but it feels that there is more than a grain of truth in her rantings. David had a wife and a five year-old son when he disappeared, so Cassie and Sunny go to inform his wife that his body has finally been found. He uses it to blackmail Colin into speaking with him. So what’s the betting on who the killer is and why?

More shocking is the revelation that the likable, friendly Lizzie Wilton was once violent, racist Beth Laws. Now’s probably not a good time to start pitching for the ethnic minority vote, Lizzie. Cassie travels to Liverpool to interview Jimmy's mother, whose life has been on hold for nearly four decades and who is desperate to learn the truth about how her son died.
