Murder in Yorkshire

Jo was the last person to see Martha Scott alive. She was helping Martha unlock a repressed memory. But during the session, Jo unlocked more than she bargained for. An alter personality introduced himself as the reincarnation of Jack the Ripper - and thanked Jo for setting him free to kill again. As Ferguson’s team race to find Martha’s killer, a series of copycat killings begin, replicating ‘The Autumn of Terror’ in 1888. But if Jack is just a figment of Martha’s damaged mind, who killed her?

On a busy train station platform, a man pulls a knife and viciously attacks another passenger before fleeing - apparently unaware of what he has just done. To the police, it looks like a terrorist attack. But forensic psychologist Dr Jo McCready has seen this bizarre behaviour before, in controversial psychological experiments. She knows this is no random killing spree. When a botched cold case resurfaces and the mistress of a controversial billionaire philanthropist is found dead, Jo discovers all these crimes are tangled up in the same web of deadly local secrets.

Jacob Malecki killed fifteen people over a thirteen-year period. At the height of the murders, Dr. Jo McCready was at university and, as an exercise, compiled a profile of Malecki, which broke open the case and helped send him down for life. Twenty-five years later a copycat killer is re-creating his murders. What's more, Malecki offers to help the police catch him from his own prison cell. Malecki claims he's repenting for his crimes. Jo doubts it, but as the body count rises, she can't ignore the killer's offer. What does he really want - and can Jo find out before anyone else dies?
