Bess, George, and I volunteered to go to Costa Rica for some R&R: rest and research. See, Corcovado Ecologica, a popular resort and preserve, isn't only a beautiful getaway; it's also a great place to study three species of monkeys. Or so we thought. When we arrived on the scene, we found the place in a shambles, and the monkeys were few and far between. And if the problem gets worse, the resort's going to be in trouble. Clearly my friends and I won't have much time for "monkeying around" on this trip -- we've got a case to crack! Catch my next case: Secret of the Spa

Bess, George, and Nancy go to Costa Rica for rest and research and end up working on a mystery.

George, Bess, and I were so excited when we won an amazing vacation at an eco-resort in Costa Rica. Fun, sun, surf -- all in the name of ecology and helping to keep our planet clean. But, as always, dirty business seems to follow me wherever I go, and this resort isn't as spic 'n' span as we originally thought. After a string of increasingly dangerous "accidents," it seems that there is a jealous predator staying at the resort, making trouble for the management and the guests. Against the urging of my friends, I know that I need to take this case and get to the bottom of it before our entire week at Casa Verde is ruined -- or worse. Can I uncover who is sabotaging the press tour before it's too late? Or will our vacation come to an unhappy end?

I'm beginning to think Sydney and Vic's marriage was doomed from the start. First Sydney's best friend, Candy, tried to sabotage the wedding. Then Vic's onscreen beau brought a knife to the ceremony -- and it wasn't just for cutting the cake. Luckily, we caught her before any damage was done.... But is she the real culprit? Or does someone else have it in for these two newlyweds? Strange things kept happening on the happiest day of Sydney and Vic's lives -- and now trouble has followed them on their honeymoon! Some things just don't add up, and I need to get to the bottom of it before Sydney -- or Vic -- is seriously hurt.

Another Nancy Drew mystery.

How about a seat at a mystery dinner on a riverboat? Yes, please! I jumped at the invitation to go along with Bess, George, and George's mom, who was hired to cater the dinner. It's all fun until there's an actual theft, and there's nothing like a good crime to stop a party. Since I've got the magnifying glass, it's up to me to catch "sticky fingers" before this dinner's sunk.

Nancy Drew and her friends investigate a murder case, that involves some members of the university basketball team.

Nancy and her friends travel to Costa Rica for a vacation, but find the resort in a shambles and most of the monkeys mysteriously gone.

Dad, Bess, and I are all set for London when Ned's Shakespeare professor asks us to do a simple favor: to take a look at his townhouse while we're there, since he can't seem to locate the housekeeper and fears something's wrong. Sounds easy enough, so I take the key. Eager to cross the favor off our list, we stop by 53 Banbury Square shortly after we land. And let's just say things in the townhouse aren't quite tip-top. And the key? Well, it unlocks a Pandora's box of serious trouble.
