Jem can't wait for school to let out for the year. Is there anything more boring than class when you could be outside? When rich boy Will brings a coin collection to school, it's an exciting treat. It isn't often the students get to see all that interesting money in one place. Then a silver dollar goes missing during recess—and Jem is blamed! After all, he's the only one who went indoors on this sunny day. When a charm bracelet is stolen the next day, more fingers point his way. Jem knows he isn't the culprit. But how can he prove it? To clear his name, Jem sets a trap for the mystery thief—his sister's gold locket lays in plain sight on his desk as bait. Will it go missing too? Or will Jem's good name be muddied forever?
