I received this book from the publishers via NetGalley in exchange for an honest review.

Sophie is an adult woman numbly going through life day by day, forever asking the same questions 'did her actions lock up an innocent man?'. Sophie's stepfather Matty Melgren has served over 20 years in jail following the brutal killings of women in North London, and it was ultimately Sophie's actions that led the police to Matty. But Matty was always the perfect father figure in Sophie's life, and he loved her and her mother. As Sophie finally arranges to see Matty in prison, the events from her childhood come back to haunt her.

This was an interesting take on a normal thriller/murder mystery - the story from the POV of a loved one connected to the serial killer but the question of Matty's innocence remains large throughout the novel and as a reader, it's fun to try and figure out if Matty is guilty.

I do think I expected a bit more from this book - it does feel like a lot of Matty's flaws and all the ways he could be a serial killer are so obvious, albeit we are getting the story from a woman who had decided he was guilty. But I never felt particularly surprised by anything that happened in this book or the direction the story took - and I would have loved a twist that wasn't extremely obvious the entire time.
