I love the Dept Q series. But unfortunately, of the 6 books, this is the weakest one. It is just long, drawn out, boring and too thin on the story line. Maybe also partly due to the translation, which is not as good as the others. Too bad. This one you can skip and you would not miss much.

I read this book in three days and loved it! I am such a huge fan! I'm already anticipating the next book!
