This long read from GQ relates the fascinating tale of Stéphane Breitwieser:
Stéphane Breitwieser robbed nearly 200 museums, amassed a collection of treasures worth more than $1.4 billion, and became perhaps the most prolific art thief in history. And as he reveals to GQ’s Michael Finkel, how Breitwieser managed to do all this is every bit as surprising as why.
There’s some really interesting stuff in this one, like this bit:
Several times, he steals while they’re on a guided tour, then casually continues the tour while holding the item. At an art fair in Holland, Breitwieser hears a shout of “Thief!” and sees security guards tackle a man. It’s another burglar. Breitwieser takes advantage of the commotion and slips a painting under his coat.
