Enjoyed this mystery set in Paris featuring Hugo Marston, chief of security at the American Embassy. While Hugo is using vacation time in the City of Lights, he visits a friend who runs a bookstall along the banks of the Seine. Later, the friend is kidnapped and Hugo works to try to find him. The mystery surrounds rare books, the booksellers union, with possible links to the drug trade. Hugo enlists help from his intrepid secretary, a friend from his past in the FBI, and an attractive journalist. I think some of the plotting could have been better, but Hugo is a likeable hero and I will definitely seek out other books in this series.
