The Art Thief

One of those books I grabbed right off the shelf at the library because it looked like it would be interesting. A super-quirky interestingly complex tale of interwoven art crimes and the ten or so people involved in perpetrating and solving them. Odd writing style (a lot of one-sided expository convos which felt super weird) but easy to not mind. The author is a noted expert in this topic and kind of a polymath so a lot of that seemed to come out in the writing of this novel.
