The Picasso Heist: by James Patterson, and Howard Roughan

A $100 million painting. 
A previously unknown Picasso is discovered in the attic of a French villa.
 
Everyone wants to possess it. 
Filthy-rich Manhattan art people. Organized crime bosses. Power-hungry government officials. A notorious forger. A glamorous twenty-two-year-old art thief.
 
Only one person knows how to take it. 
She’s the rival none of the power players see coming.
