The Art Thief by Michael Finkel is a true-crime book about Stéphane Breitwieser, one of history's most prolific art thieves, who stole over 200 priceless objects from European museums, often in broad daylight, without violence, and for the love of possessing beauty rather than for money, displaying them in his attic bedroom until his downfall, which involved his girlfriend and a shocking betrayal. The book details his audacious heists, his relationship with his accomplice, and the psychological obsession that drove him, blending crime, psychology, and art history into a riveting narrative.
