The attack is a brilliant feat of planning and secrecy, except for a single thread.The thread leads legendary spy, art restorer, and assassin Gabriel Allon and his team to the south of France and the doorstep of Jean-Luc Martel and Olivia Watson. A beautiful former fashion model, Olivia pretends not to know that the true source of Martel’s enormous wealth is drugs.
