My Hero

When a mugger attempts to rob Winnie and Christian, he is fought off--by Winnie. When the story gets around school, the assumption is that Christian drove the mugger off and rescued Winnie. Christian is afraid to let the truth be known lest his reputation be ruined. But that is exactly what happens. Meanwhile, the other roommates find two parts of a treasure map in their rooms, setting off a wild search for the $5000 booty.
