The Consorts of Death by Gunner Staalesen
In 1974 the same boy had surfaced in connection with a sudden death in his new home. And then again ten years later, in connection with yet another case: a dramatic double-murder in Sunnfjord. The small boy is now an adult, and on the run in Oslo, determined to take revenge on those responsible for destroying his life, among them the former child protection officer, now detective Veum.
