The abduction of five-year-old Matthew Farraday provokes national outcry and a desperate police hunt. And when his face is splashed over the newspapers, psychotherapist Frieda Klein is left troubled: one of her patients has been relating dreams in which he has a hunger for a child. A child he can describe in perfect detail, a child the spitting image of Matthew.

Detective Chief Inspector Karlsson doesn't take Frieda's concerns seriously until a link emerges with an unsolved abduction twenty years ago and he summons Frieda to interview the victim's sister, hoping she can stir hidden memories. Before long, Frieda is at the centre of the race to track the kidnapper. But her race isn't physical. She must chase down the darkest paths of a psychopath's mind to find the answers to Matthew Farraday's whereabouts. And sometimes the mind is the deadliest place to lose yourself.  

The rotting, naked corpse of a man is found amidst swarms of flies in the living room of a confused woman. Who is he? Why is Michelle Doyce trying to serve him afternoon tea? And how did the dead body find its way into her flat?

DCI Karlsson needs an expert to delve inside Michelle's mind for answers and turns to former colleague, psychiatrist Frieda Klein. Eventually Michelle's ramblings lead to a vital clue that in turn leads to a possible identity. Robert Poole. Jack of all trades and master conman.

The deeper Frieda and Karlsson dig, the more of Poole's victims they encounter . . . and the more motives they uncover for his murder. But is anyone telling them the truth except for poor, confused Michelle?

And when the past returns to haunt Frieda's present, she finds herself in danger. Whoever set out to destroy Poole also seems determined to destroy Frieda Klein.

Sometimes the mind is a dangerous place to hide.

Psychotherapist Frieda Klein finds she has an unusually personal connection with DCI Karlsson's latest case. She is no longer working with him in an official capacity, but when her niece befriends Ruth Lennox's son, Ted, she finds herself in the awkward position of confidante to both Karlsson and Ted.

When it emerges that Ruth was leading a secret life, her family closes ranks and Karlsson finds he needs Frieda's help more than ever before.

But Frieda is distracted. Having survived an attack on her life, she is struggling to stay in control and when a patient's chance remark rings an alarm bell, she finds herself chasing down a path that seems to lead to a serial killer who has long escaped detection. Or is it merely a symptom of her own increasingly fragile mind?

Because, as Frieda knows, every step closer to a killer is one more step into a darkness from which there may be no return . . .
