The Otterbury incident

Two groups of boys in Otterbury spend their days play-fighting each other but one day a window in the school is broken. To pay for the window, the two groups come together to earn money, but before the money can be given to the school, it is stolen. The boys must quickly figure out who committed the theft and recover the money before the payment for the window is due.

An exciting story, full of action, well told, with occasional illustrations.
