Friar Edwin Leahy is the young, driven headmaster of St. Benedict’s Prep at the time when Robert Peace is a student there. He’s instrumental in motivating Robert to do great things at a high school student, and it’s likely that, had Leahy not spoken to Charles Crawley, Robert would never have been able to go to Yale. In many ways, Leahy is the character in the book who most resembles Jackie Peace: they’re both hardworking, selfless people who try to help the people they love, and then experience the heartbreak of seeing those people ruin their lives.
