The acclaimed author of the Kurt Wallander mysteries, writing at the height of his powers, now gives us an electrifying stand-alone global thriller.

January 2006. In the Swedish hamlet of Hesjvallen, nineteen people have been massacred. The only clue is a red ribbon found at the scene.

Judge Birgitta Roslin has particular reason to be shocked: Her grandparents, the Andrns, are among the victims, and Birgitta soon learns that an Andrn family in Nevada has also been murdered. She then discovers the 19th-century diary of an Andrn ancestora gang master on the American transcontinental railwaythat describes brutal treatment of Chinese slave workers. The police insist that only a lunatic could have committed the Hesjvallen murders, but Birgitta is determined to uncover what she now suspects is a more complicated truth.

The investigation leads to the highest echelons of power in present-day Beijing, and to Zimbabwe and Mozambique. But the narrative also takes us back 150 years into the depths of the slave trade between China and the United Statesa history that will ensnare Birgitta as she draws ever closer to solving the Hesjvallen murders.
