Matty Melgren is a convicted serial killer serving life without parole for the murders of several women in North London in the 1980s. He has consistently protested his innocence, and the evidence against him was largely circumstantial. So was he really guilty?

At the time of his arrest, Matty’s girlfriend, Amelia-Rose, is a single mum to her 12-year-old daughter Sophie. Matty had been a big part of their lives since they moved to London from Massachusetts a few years earlier, and Sophie adores him. He’s handsome, funny, respectable, and never in a million years would she or her mum suspect him capable of the brutal killings that are dominating the headlines.

Then a sketch of a suspect is released by the police that looks very much like Matty. As more women disappear, a pattern emerges – the victims all resemble Amelia-Rose, with dark, straight hair parted in the middle. It couldn’t really be him. Could it?

Whilst her mother starts drinking heavily, Sophie is consumed with doubt and a guilt that will cause her to act impulsively, ripping her family apart.

​Years later, Sophie is still haunted by her actions. Was she wrong to have done what she did all those years ago, or was she wrong not to have acted sooner? Then she receives a letter from Matty, telling her he’s dying and asking her to visit him in prison. Will she finally get the answers she needs to be able to re-claim her future? Answers that will come at a devastating cost…
