This is book 6 in the Department Q mysteries.  I just love this series, Carl, Assad and Rose are a great team.  Their interactions and methods of working drive the story along at a nice pace.  In this outing of the series, Carl receives a call which he as no interest in getting involved in.  The caller kills himself and a very reluctant Carl and his team are dragged in to look at a cold case that was the catalyst for the suicide.

Great sense of place, great (and in some instances tragic) characters, an interesting plot involving an obscure religious cult, and obsessive love come together to create an engaging novel.  I didn’t see the end coming and thought the resolution was really cleverly done.  A great, well written mystery, in a series that continues to be one of my favorites.
