In the final novel of the trilogy, The Weakness of Victoria Bergman, the pieces of an unprecedented puzzle fall into place. Stockholm Police Commissioner Jeanette Chilberg takes her investigations to their logical extreme. In this, she gets a lot of help from the advice of her friend and lover, psychotherapist Sofia Zetterlund. Sofia carefully guides the police on the trail of the people who disfigured her childhood, her personality and her daughter, and meanwhile she finishes her own work, the goal of which is the return of Victoria Bergman.

However, they are not the ones who complete this story. History itself crawls back to where it began more than half a century ago, and dissolves in the horror that gave birth to it.
