Greetings. This is Professor. I knew something might go wrong, so you became a part of my plan. And you did admirably, even though you had the most difficult role in the whole enterprise. Mine.
Let's call you "The Professor's club". Sounds good, doesn't it?
We got away with the Goya paintings and the museum doesn't even know it happened. They will open up with the fakes and it might take them months to figure out something went wrong. By then we'll be warming our bones on some tropical island.
Good job. I think it's the last one. The last score… though, I heard of a rare emerald, being auctioned in London in three months… If you're interested, just stay put. I'll know where to find you.
