I really really liked this one. The translation is very well done, so I hope the original German was as good (and that the translation is accurate). I kicked myself at the denouement, but it wasn't terribly surprising. I'm not sure I agreed with Bea's role at the end (I can't really describe that without too many spoilers), but that's probably my only complaint.

I really enjoyed the geocaching aspect of the story. Maybe I'm a little too much of a nerd, but I did find Bea and Florin's lack of knowledge about the activity to be a little unbelievable, though I'm glad there was another member of the police force who did know about it.
