"Based on the series by Carolyn Keene."
"In "The Fake Heir" Nancy, along with Bess and George, find the wreck of an old yacht with a safe inside full of jewelry worth a small fortune. Cousins of the Druthers owned the yacht and their will leaves everything to Mr. Druthers, but no one's seen him for ten years. The rumor is Mrs. Druthers murdered him! Things take a surprising turn when suddenly Mr. Druthers reappears! But then Mrs. Druthers disappears! Join Nancy Drew as she solves the mystery of the fake heir! Then, in "Mr Cheeters is Missing" when the eccentric Blanche Porter reports that her beloved Mr. Cheeters has vanished, it isn't your standard missing persons case. As Nancy Drew soon discovers, Mr. Cheeters, is a pet chimp. Or is he? Based on a preliminary investigation and information obtained from Blanche's brother, Lawrence, the River Heights police dismiss the case as bogus - doubting that there ever was a Mr. Cheeters to begin with. But when Nancy Drew discovers there's a missing diamond necklace as well - she's on the case!" --
