Apparently I read this already 9 years ago, but I remembered none of that when I just read it (again).

But what I wrote then still stands. I am a sucker for good detective stories and if they happen to cross over to my other favorite genres, such as sci-fi or fantasy, I enjoy them even more. Scalzi knows how to write an entertaining book. The writing is not perfect, the dialogue a bit too quippy at times. But it's still an entertaining story. Recommended if you enjoy detective stories in a sci-fi setting.
