Stéphane Breitwieser steals art not simply for profit, but because he wants to possess the beautiful objects that captivate him. With his girlfriend serving as lookout, he targets museums and cathedrals across Europe, carrying out more than 200 heists and taking over 300 works in nearly a decade. His eye for art and ability to read security arrangements make the thefts possible, but repeated success fuels an increasingly reckless obsession. Michael Finkel traces the extraordinary collection, the relationship that sustains the crimes and the mounting risks Breitwieser refuses to acknowledge. The account follows his escalating compulsion toward the act that finally brings everything down.
