Vjeran Tomic, French catburglar

The Atlantic has a long article about Vjeran Tomic a French art thief.

Tomic generally worked alone, scaling walls, leaping between rooftops, and picking locks. Once inside an apartment, he looked first for jewelry, because it was valuable and easy to sell. A burglary that took less than two hours often yielded enough cash to support him for six months on the French Riviera. In his letters, he recounted robbing various Parisian luminaries, including the French-Caribbean singer Henri Salvador and the Egyptian royal family.
