The Drackenberg Adventure

Who could resist a once-in-a-lifetime invitation to the Grand Duchess of Drackenberg's Diamond Jubilee Celebration? Not Vesper Holly! Off she goes, with her guardian, Brinnie, and his wife, Mary, and plunges into a plot involving a takeover attempt from neighboring Carpatia.

In short order, Vesper finds herself mixed up with Gypsies, a kidnapping, and the discovery of a priceless Leonardo da Vinci portrait. Vesper has her hands full. Especially when the despicable Dr. Helvitius shows up. Will Vesper be able to save the day—and Drackenberg?
