 How does Eddie’s interest in radioactivity affect the story’s plot?
Still, one clue is as good as another when it comes to hunting uranium ore, I guess. In fact, anything having to do with atomic science excited him. You couldn’t have a father who was head of the atomic-science department at Oceanview College without picking up a little knowledge along the way.

His father usually volunteered any information he wanted known, so Eddie stuck to questions which could and would be answered.
