Query: A good read

Not as predictable as some reviewers would have you believe. City of Shadows is a step up from the Mistress of the Art of Death series, which puts it at a pretty high level. Ms. Franklin's writing was already excellent and gets better here. Her plotting is complex (but remains believable), she does a wonderful job of fleshing out her characters, and she uses the setting and time (Berlin between the wars), and what we know about what's coming, very effectively in racheting up the suspense. Even the sprinkling of cameos by historical figures (Hitler, Goering, etc.) make sense and were non-gratuitous -- a nice change from most of the current crop of historical novels. A very enjoyable read.
