Trama
In 1994, two teenage twins are found brutally murdered and a number of clues point to some pupils from a nearby boarding school, but the case is closed as a local outsider pleads guilty and is convicted for the murders. 20 years later, the case ends up on Carl Morck's desk and he soon realises that something is terribly wrong. Carl and Assad try to track down a key witness, but they are not the only ones looking for her as powerful people try to protect their secrets.
