Rex and his friends begin grade six against the backdrop of the 1962 Ban the Bomb protests on Parliament Hill. But once again it is trouble on the home front that has Rex's attention. Why is his father so insistent that Rex go with him to the November Remembrance Day services, and why does Dad become so sad at this time every year? Why does he have a stash of secret photographs and letters -- written in German? How can Rex deal with the new teacher, Miss Garr, a manipulative bully?

Yet all these problems pale when Rex finds an abandoned address book in a phone booth and sets out to find its owner. When the owner turns out to be the beautiful but desperate Natasha, the victim of an abusive husband, Rex finds himself wishing he had heroic powers so he could rescue this damsel in distress. Storybook solutions, it turns out, are no match for real-life adult problems, and once again Rex finds the answer in his own ingenuity and with the help of good friends.
