After identifying the body in the cellar as Jimmy Sullivan, the hunt for his murderer begins. Cassie and Sunny begin the investigation by following up on the names written in Jimmy’s diary. In Liverpool, Cassie meets Jimmy’s mother, who is relieved at the prospect of finally finding out what happened to her son after he went missing. The name ‘Frankie C’ is identified as Sir Phillip Cross – a newly government-appointed entrepreneurial czar. However Sir Phillip denies that he ever met Jimmy. ‘Beth’ is revealed to be Lizzie Wilton, who lives in Croydon. She also denies knowing Jimmy but it is clear she was a very different woman in the 70s, before her current marriage.
