description: Paris MacKenzie is an independent and brash 16-year-old American visiting her namesake city at the turn of the century. In this fourth book in the series, she helps her friend Violette with a test run of Violette's experimental diving bell. They recover a trunk which is the first clue to the theft of a priceless 50-carat diamond, Napoleon's Fist. The trail leads to Violette's aunt, Madame Meduse, a former enemy of Paris', and eventually to Paris' father. The fast-moving plot returns the diamond to the Louvre, exposes Meduse's involvement with the Fist as a way to buy Violette into the French scientific community, and reveals Violette and Paris as half-sisters.
