There are two crimes in this book: A bank robbery that ends in a murder and an apparent suicide of a young woman. Both are loners by Harry, this time solved in a team with a new young colleague. But: Every time a case is resolved, emerges a new indication or a new subject and it comes back again and again deeper into the story. That's very, very cleverly designed, a bit like archeology, where the removal of a layer reveals new mysteries. But it makes the book too long, sometimes even long-winded. I have now and again at the thought of getting caught: My goodness, but now everything is clear! What comes for the next x-hundred pages? What helped then to put down the book and read something else, each new entry was exciting again with the new view of history. Conclusion: good, recommended reading for people with staying power, who appreciate a very well thought-out plot construction.
