The Bookseller

I very much enjoyed The Bookseller by Mark Pryor which is set in Paris.  Hugo Marston is head of security at the American embassy and he's very keen on old books.  He regularly visits a book stall owner - a bouquiniste, named Max till he witnesses an incident near the book stall which sets Hugo on a dangerous path involving crime gangs in Paris.  Hugo then notices that these prized book stalls are being taken over by new people.  Max had sold Hugo a couple of rare books and they become very significant to the story.  Hugo meets a beautiful young journalist and she helps him investigate what is going on.  Then a former friend from the CIA comes to visit and he also becomes involved.  There are twists and turns and violent confrontations before the investigation is completed. 41/2/5
