Who is Lucy McLaren from Ghost Girl: The True Story of a Child in Peril and the Teacher Who Saved Her and what is their importance?

Lucy McLaren is the teacher whose room is next door to Torey's class. Lucy often helps Torey with her students. She is also the one who tells Torey that Mrs. Harriman committed suicide. Torey talks more to Lucy about her problems with Jadie than any other teacher at Pecking School. However, since Lucy has grown up in and has always lived in a small town, she is unable to understand the kind of abuse to which Torey believes that Jadie is being subjected. Lucy believes that simply because they live in a small town, there should be no abuse happening in their area. When Torey does report Jadie's story, however, it is Lucy who tells Torey that she believes that Torey did the right thing.
