I think it's so much fun to stumble upon a book whose plot revolves around art.
While searching among the shelves of the "new" library I found an entire shelf of books by author
Aaron Elkins. He has a couple of mystery series: one about a forensic anthropologist who finds and solves crimes the world over and another about museum curator, Chris Norgren, who solves crimes that happen in the art world. Chris might find himself examining a newly discovered Rembrandt (authentic or fake?) or flying off to the Louvre to discover a killer (the collector or the gallery owner? ) It's just fun to read about all this juicy intrigue that goes on in the world of artists, forgers, museums and galleries.
