Some equestrians are up to more than horseplay in this third book of the Nancy Drew Diaries, a fresh approach to a classic series. At the prestigious—and competitive—River Heights Horse Show, the prizes, which range from money to possible placement on the Olympic Team, are so highly coveted that anyone from the riders to the owners will do anything to win…even drug the horses! Who’s up to no good? Nancy, Bess and George are on the case!

Nancy and her friends need more than book smarts to get to the bottom of a literary mystery in this fourth book of the Nancy Drew Diaries, a new take on the classic series. A rash of crimes in a neighboring town—a blazing fire at a bookstore, a boat that sinks in the harbor, and a valuable dog’s dognapping—are eerily similar to the plots from famous mystery writer Lacey O’Brien’s popular books. So who’s behind the crimes? Could it be Lacey looking for publicity? One of Lacey’s superfans? Or maybe it’s Paige Samuels, owner of the bookstore that burned. Nancy, Bess, and George will have to read between the lines as they dig deep into a dangerous mystery.

Nancy and her friends Bess and George tour the dangerous waters off the coast of Alaska on a posh new ship's maiden voyage, a journey that is overshadowed by a series of deaths and near-misses that reveal the work of a saboteur.

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, who are clients of Nancy's dad Carson Drew, owned the yacht. Their will leaves everything to Mr. Druthers, specifically excluding his spouse, (whom the cousins hated), but no one's seen him for ten years and the rumor is that 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!

Nancy Drew's keen mind is tested when she searches for a missing will.
