This is a rather graphic presentation of the horrors of Alzheimer's disease. Kurt Wallander has been slipping away. Most of his colleagues and the people around him are clueless, although they suspect he is ill. The case he is trying to solve the murder of a police officer. The officer's partner has pretty much gone rogue. She accosts one she suspects and locks him up in a large wooden crate. She threatens him because she believes what happened was caused by someone higher up. Wallander is in and out, his memory failing, his resolve slipping. He becomes so frustrated that he alienates Linda, who has done everything she can to cover for him. Hanging over this entire episode is the terror he feels at his loss of control. I have known numerous people who have succumbed to Alzheimer's, including members of my family. It must be so hard to see things disappearing in your brain. Maybe some would rather ignore the human side of this series, but I felt there was a sincerity and reality here that trumps the normal plot line.
