I learned about this book because Wolfgang Welt reviewed it when it came out originally. I can't remember what he wrote about it, but it made me curious enough to read it.
Without wanting to give away too much of the content, it can be said that the book hit me like a truck. Questions as to what I was reading here and why I got to read this accompanied me throughout the entire book. At times I was wondering if it was fictitious or for real (spoiler alert, it's real), hoping that the afterword by criminologist Herbert Jaeger would be able to answer my questions. But in the end, all of this doesn't matter, it's really just a good book.
