Mary Louise

A spirited fifteen-year-old day scholar at a modest boarding school navigates friendships, school rules, and family ties while mediating disputes among classmates. She balances loyalty to peers and respect for authority as a mysterious theft, an official investigation, and a sequence of social intrigues draw her into episodes involving a hired girl, a stolen book, and a daring escape. Through cleverness, moral reflection, and aid from Gran'pa Jim and unexpected allies, she uncovers the truth, confronts mistaken judgments, helps restore fairness, and arrives at reconciliations that are clarified by a final revealing letter.
