Harvey the West Highland Terrier, hero of Harvey Comes Home, is back with his beloved Maggie. He is also back at Brayside retirement home, where he and Maggie now volunteer along with their friend Austin. There Maggie is drawn to a new resident, Mrs. Fradette, who tells stories of learning to fix cars as a twelve-year-old during the flood of 1950. Mrs. Fradette, with her bold fashion and love of poker, doesn't fit in among the beige-cardigan-wearing, bridge-playing ladies of Brayside, but she doesn't seem to care. Maybe that's why Maggie likes her so much. Since seventh grade began, Maggie hasn't been fitting in well with her friends, either. Harvey has a problem of his own. He can smell an intruder in his yard, and he needs to find it. He is so intent on the nighttime fiend that he almost doesn't notice how worried Austin is about his grandfather, who has been Brayside's custodian for longer than Harvey has been alive. It seems like the retirement home is planning to give the job to a younger man, an injustice that Austin can't let pass unchallenged.
