About halfway through this, I was convinced I was going to hate it. The fact that I rated it so highly, shows how beautifully all the strands came together at the end.
It started by introducing us to the narrator (who is also the author), who is locked away in an apartment frightened for his life. It then cuts to 12 years in the past where the narrator meets Henry Morgan, a charming, outgoing musician/bit part actor/boxer, who the narrator has an immediate connection with. Klas (the author) moves in with Henry, and they become close friends. We learn a little bit about Henry's past, and the fact he has a brother in America. Several new minor characters are introduced, and Henry lets Klas in on a big secret. At this point, Henry's brother Leo appears, and admits he has been in an asylum.
At this point, the story jumps back 30 years or so and tells the back story of the Morgan brothers. Starting with their childhoods, it details several key moments in each brother life. This was the point where I got a little lost. So many characters are introduced and then left behind, I found this a little confusing. However, the pace picks up significantly towards the end of the middle section, and by the time I reached part 3, where all these strands begin to come together, I was enjoying it immensely.
The style of writing is beautifully descriptive, and the shear depth of prose meant that it is easy to miss some clues early on. I found myself tracking back at several moments, this didn't detract from my enjoyment
My only slight criticism is that all the threads aren't quite tied up at the end. The ending is ambiguous, but I suppose the author is trusting the reader to use their own imagination. Some people might find that frustrating, but to me it ended the book perfectly.
I was interested to hear that sequel, called "Gangsters" has been published. Apparently it attempts to resolve all the threads established here. Unfortunately, an english language copy at a reasonable price does not appear to be available, but once it does, I'll give it a go
