What does Granger think about books? What is Mrs. Phelps role in the story?

An intellectual and former author, Granger is the leader of the group of hoboes that Montag meets along the tracks after fleeing from the police and Hound. Like Clarisse and Faber, Granger is a sympathetic character who loves books. He reveres them so much that he and his friends have memorized famous works of literature. Mrs. Phelps is Mildred's friend. Much like Mildred, she is lost in the superficiality of society. She is however touched by Montag's poem.
