Every morning retired naval officer Håkan von Enke takes a walk in the forest near his apartment in Stockholm. Then, one day he fails to come home. Detective Kurt Wallander is not officially involved but Håkan's son is engaged to his daughter Linda. A few months earlier, at Håkan's 75th birthday party, he was eager to talk to Kurt about a controversial incident from his past. Could this be connected to his disappearance? When Håkan's wife Louise also goes missing, Wallander is determined to uncover the truth but the investigation will force him to look back over his own past, as he comes to the unsettling realisation that even those we love the most can remain strangers to us. And then an even darker cloud appears on the horizon...The return of Kurt Wallander, for his final case, has already caused a sensation around the globe. The Troubled Man confirms Henning Mankell's position as the king of crime writing.
