It's the beginning of a new year and Petra is back after her breakdown with more questions than answers. She has been unable to find out who she is or who she was before she woke up in a hospital bed with amnesia or why she needs so many drugs to keep her alive. Why is there a second entity in her head and why did it try to turn her into a psychotic killer?

For the moment though, Petra has more important things to worry about. One of her new friends is being abused and the discovery has disastrous consequences for Petra. A near death experience on holiday unexpectedly uncovers some of her past and results in a holiday romance. Her relationship with Jenny becomes more complicated.

Inspector Fransson is still searching for his elusive serial killer. Why were two French Gentek scientists murdered and where is their daughter? Why did their German colleagues disappear, only to reappear in England as University Professors? Where is Petter Ulfson, his prime suspect, and who is Petra Connell?
