The Purity of Vengeance: A Department Q Novel (Unabridged‪)‬

New York Times bestselling author Jussi Adler-Olsen returns as Detective Carl Mørck and his Department Q team delve into a cold case that turns into more than they may be able to handle... 

In 1987, Nete Hermansen plans revenge on those who abused her—especially Curt Wad, a surgeon who was part of a movement to sterilize wayward girls in the 1950s. More than twenty years later, Detective Carl Mørck already has plenty on his mind when he is presented with the case of a brothel owner, a woman named Rita, who went missing in the eighties: New evidence has emerged in the case that sent Carl to Department Q.

But when Carl’s assistants, Assad and Rose, learn that numerous other people disappeared around the same weekend as Rita, Carl takes notice. Sifting through the evidence, they inch closer to Curt Wad, who is still committed to his twisted beliefs, and whose treatment of Nete only hints at his capacity for evil.
