Claudia and the Baby-Sitters investigate after she’s accused of cheating in this whodunnit from the charming hit series. For once, Claudia’s studied really hard for her math test. And when she gets her paper back, it has an A- on it. All right! But then Claudia’s math teacher calls her to his desk and accuses her of copying off of Shawna Riverson’s test. Claudia can’t believe it, and neither can the Baby-sitters. Claudia would never cheat! And they’re not going to rest until they help clear Claudia’s name! The best friends you’ll ever have—with classic BSC covers and a letter from Ann M. Martin!
