Misha: That's a lot of information. And so far we've only learnt about Washington and Jefferson. Emily: I don't think that Robin MacWizard knew very much about them himself. Mark: I agree with you. We must find a simpler answer. Emily: What did you say? Of course! How could I be so stupid? There's a very simple answer. All the presidents lived in Washington in their official residence, which is called the White House. Misha: You're right! I heard that every American president has lived there. We must go to Washington. Mark: I'm not so sure about that. In his note Robin only wrote about four presidents, not about ALL of them. Rob: Don't be such a bore, Mark. We have to check every idea. Emily: And look. Now the meaning of the picture is clear: there is a big letter "W" written here. It means Washington or the White House. I'm sure we're on the right track. Misha: Yes, but Washington isn't just round the corner. Emily: It's not so far away. If Grandma Olga agrees to take us by car, we should be there in less than six hours. I'll go and talk to her and you pack your things, guys. We should hurry up.
