Entertaining and interesting despite being written to the same formula as all the other books in the series. I keep coming back for more despite always getting annoyed at the bit where Ruth plunges alone without a torch down the steps to a dark cellar filled with murderers (not literally, but she always does that kind of lumbering into danger thing). Actually I really liked the bit where the metaphorical torch was actually an iPhone with a dying battery and no signal, I could relate! I guess the good outweighs the predictable here.
