steve berry has some excellent novels out there. the main character is a former US Agent, he now resides in europe and goes on these quests that typically involve some aspect of history...or historical myth. my favorite thus far has been "The Amber Room". the story is based on the amber room in russia and how the original was dismantled, hidden etc.
I think he has written 5 or 6 different books, each with a different theme, but the same character.
