Former Head of Department Q Carl Morck has retired. That was the plan, at least. So when he comes across a disturbing audio recording, he turns it over to his former colleagues, who are struggling to keep the old Department up and running on their own. That is, until a new transfer unexpectedly arrives – Helena Henry, a Frenchwoman who throws herself into the investigation with gusto . . . but who may also have secrets of her own. As the team realizes that the audio recording might shed new light on a seemingly open-and-shut murder-suicide case from years earlier, suddenly everything they thought they knew about the case is called into question. And meanwhile, a spurt of seemingly random violence – an explosion off the coast of Jutland, a young woman shot dead in Copenhagen – sets the Department Q team investigating a possible connection to a different long-ago dark and sinister event, one that someone has never forgotten.
