This was probably a great book– after all, Mathews clearly knows how to write great thrillers. Sadly, I found it turgid, slow-moving, and dull. The characters were wooden (bad German? check. spunky American heroine? check. lily-livered French diplomats? check. You get the idea.) The big secret of the plot goes essentially nowhere. Reviews on Amazon praise the intricate detail that Mathews lavishes on describing 1940 Paris. If that’s your thing, you might like this book, but I sure didn’t.
