Well, the brothers were having a chat, and they started to wonder what would happen to a completely honest and intelligent stranger who was in London with no friends, and with no money but that million-pound bank-note, and no way to explain why he had that bank-note with him. Brother A said he would starve to death; Brother B said he wouldn't.
Brother A said he couldn't take the banknote to a bank because he would be arrested at once. So they went on arguing till Brother B said he would bet twenty thousand pounds that the man would live thirty days, at least, on that million, and keep out of jail as well. Brother A accepted the bet. Brother B went down to the Bank and bought that note. Then the brother dictated a letter, which one of his clerks wrote out in a beautiful round handwriting. After that the two brothers sat looking out of the window all day. They were looking for the right man to give the letter and bank-note to.
They saw many honest people go past, they they were not intelligent enough. Other people were intelligent, but they not were honest enough. Many people were honest and intelligent, but they were not poor enough. If they were poor enough, they were not strangers in London. There was always something wrong, until I came along. However the brothers agreed that I was exactly what they were looking for; so they had chosen me without arguing about it. And now here I was, waiting to find out why they wanted to see me.
