The Rembrandt Affair by Daniel Silva

I recently finished The Rembrandt Affair by Daniel Silva it is about an art restorer who is also an assassin who woks for the Israeli government. He finds out that a painting that was stolen during the holocaust that has a list of names of Jewish people who's belongings were taken hidden inside of it and is trying to find it. he ends up making a mission to strip the wealth of one of Europe's wealthiest men and successes. the reason he was successful is because the wealthy man's fortune was based off of stolen property during the holocaust which they took back and the wealthy man was now poor.
