Nicknamed "The Eagle" for his unerring intuition, detective Hallgrim Hallgrimsson exudes competence and self-assurance but beneath the facade is a tormented personality. A cunning and ingenious hero, Hallgrim has allowed work to consume his life and prevent him from connecting with himself, his darkest memories and his motivations. Ultimately, a personal crisis forces him to launch another, more introspective investigation: that of solving the mystery of his own life.
