This is the 3rd book in the Korner and Werner series which is set in Copenhagen Denmark. Fifteen-year-old Oscar Dreyer-Hoff disappears. The police think it is a typical runaway case but his family fear the worst as Oscar left a peculiar note. I found the reference quote to Oscar Wilde's Picture of Dorian Gray interesting. Detectives Jeppe Kørner and Anette Werner uncover lots of secret happenings which keep the pages turning.
