We’ve proved that one is a fake, the experts believe that three of the others are copies, and then there are the two that might be Sisleys and are only waiting for a method to prove it. And we have one more that science managed to prove was really old. I’m sure that in a few years methods will be developed to tell us exactly who painted it.

“And now let’s make arrangements for our trip to Holland.”
