Chapters 6-9 (pp. 48-109)

What does Amir put under Hassan's mattress? Why does he do it?

Amir puts some money and a watch under Hassan's mattress to get himself in trouble, but to his suprise, Hassan tells Baba that he did do it!  Baba forgives him instantly, even though in his opinion, theft is the worst sin of all; the only sin in fact!  Hassan has proved his loyalty to Amir yet again.
