Igi Heitmann is being stalked. In the suburb of Oslo where she lives with her cross-dressing husband and their daughter, someone is spray-painting the walls of the houses. HEITMANN = CHILD KILLER, the graffiti says. Who would think this, and how do they know where she lives? On a bitter winter's evening, Igi attends the opening of the exhibition of an avant-garde artist whose use of violent pornography has caused great controversy. A video is playing, showing a young man being strangled as part of a sado-masochistic sex game. Moving between the world of violent pornographic art and the happy life she shares with her husband and daughter, Igi must follow a dangerous and shocking path to the truth. An Igi Heitman mystery.
