A Riviera socialite's diamonds are stolen—the latest in a string of seemingly unconnected but increasingly audacious jewelry heists across France—Peter Mayle's bon vivant and master sleuth, Sam Levitt, and his partner, Elena Morales, are soon on the case. In this fourth book in the series (following The Corsican Caper), Sam sees the hand of a master criminal, but as he and Elena dig deeper, they begin to realize just how dangerous it may be to pursue the truth.
