The French Code — Deborah Abela

When a leading archeologist disappears from the Louvre, the world's most famous museum, Spyforce agents Max, Linden and Toby are sent to France to mind his spoilt daughter. But Monsieur Marceau has left an encrypted message for his daughter, and the police aren't the only people interested in what Veronique knows. Who has kidnapped Marceau, and why? The three superspies soon discover that the answer involves mysterious codes, secret graveyard meetings, underground torture chambers in medieval castles, and the wonders of ancient Egypt. Will Max crack the puzzle before it's too late?
