I have read, or listened to, most of the Wallander books. I thoroughly enjoyed them. This book is no exception. I was very intrigued by the plot, the characters and the fascinating historical aspects. I was, however, most engrossed by Wallender and what in essence is his "aging process" and the interaction with life - which marches on relentlessly. As someone of Wallender's age, I was morbidly fascinated by his descent into eventual darkness. I am glad, that Mankell chose to give a defined ending to Wallender - one that is unfortunately too common amongst all of us - reminds us that all of us have a human commonality, regardless of our social standing, professional career, etc. I also think that some of the "loose ends" at the end, reflect not only the "espionage" component of the story, but I think also reflect a reality of life - not everything can be answered to one's complete satisfaction - sometimes, things are just vague and unclear (much like our minds?). I am glad that I still have a few Wallender books to read.
