Third in a series of four books, we see Rose off to Venice in pursuit of the villain behind the attacks in Book 2.Again there are quite a few contrivances in this story (and a rather convenient despatch of the villain). I liked this less than the previous two books - in part because of the "protective" dynamic between Rose and Bill, and the recurrent inconsistencies of characterisation, but am still intrigued enough to see who Rose really is to read the final book in the series.
