I'm reading a book

I can't put it down.  If I had to assign a genre to it, it would be British Police Procedural, but that's just a part of it.  Even though I haven't finished it, I've already ordered more from the library.  The author is Nicci French, and the book is described as a Frieda Klein mystery. The title is "Day of the Dead", and it's the most recent mystery in the series.  I certainly plan to read more of them.
