The Hardy Boys: The Mystery of the Applegate Treasure

Frank and Joe Hardy are the sons of Fenton Hardy, a famous private detective. Finding everyday life at home in Bayport dull, the boys hope their father will let them work on one of his cases. Disappointed when he tells them his work is too dangerous for children, they are more determined than ever to follow in their dad's footsteps, and solve mysteries.
