Is This a Nancy Drew or Hardy Boys Book Title?

"The Secret in the Old Attic" is part of the Nancy Drew collection, and details a case in which Nancy helps an elderly man find an attic treasure that could net him a lot of money. Suddenly, the attic is not nearly as scary.

Nancy Drew goes on a trip to Florida and visits Crocodile Island to help track down evil poachers. Things don't quite go as planned when Drew's group is kidnapped. "Mystery of Crocodile Island" was first published in 1978.

Frank and Joe had their work cut out for them in this book, dealing with spies, smuggling and top-secret information. Luckily, they're just the team for the case, and the bad guy goes down as usual.

In fairness, the mask itself came to be after the coins melted, so it all ties in together. The Hardy Boys are on the case, though, helping to find the missing Native American mask and return it to its rightful owners.

Nancy Drew's on tap for this one, working to help find a missing will to make sure the Turner family, rightfully, can lay claim to Josiah Crowley's estate. This story is one of the best-selling Nancy Drew mysteries of all time.

The Hardy Boys are summoned to help find a will (sound familiar?) after a boarding school headmaster dies and leaves his grandson with unanswered questions. Presumably, the will holds the key to it all.

"The Flickering Torch Mystery" is something of a mystery in itself. The original book involves the disappearance of silkworms from a lab while the revised edition delves into a plane crash and a nightclub. Either is a good read, though!

You just knew Nancy Drew had to be involved if there was a diary to explore, didn't you? "The Clue in the Diary" involves the appearance of a mysterious diary and both the clues from the book and the fire itself.

It's the Hardy Boys again, back in "The Crisscross Shadow" to help foil a plot to steal from a Native American village. The boys locate a missing deed (and a host of valuables) and save the day.

Nancy Drew jets off to Hawaii in "The Secret of the Golden Pavilion" to get to the bottom of an inheritance that may fall into the wrong hands and to figure out the secrets of the Kaluakua estate.

Don't get excited; "The Password to Larkspur Lane" has nothing to do with the internet and a missing website password. Instead, it involves a message delivered by a carrier pigeon and the kidnapping of a whole group of people.

Is it odd that the Hardy Boys are breaking into a house at the same time they thwart a break-in attempt by someone else? If you like to read about burglary, kidnapping, getaway attempts and plane crashes, this is the mystery for you.

A military general is seeking to clear his name in "The Secret of the Lost Tunnel" with Frank and Joe's help. All the Hardy Boys have to do is locate the missing gold that has long since been buried. Easy-peasy.

The events of "The Sign of the Twisted Candles" take place at a roadside inn of the same name. There's lots of family strife, even for Nancy herself, in this ninth entry of the Nancy Drew chronicles.

"The Sinister Signpost" is a Hardy Boys mystery that involves proprietary information about a car engine potentially being stolen from its rightful owner. A horse farm also plays into the plot of the story. Seriously.

Frank and Joe are on the case of a criminal and an illegal drug smuggling ring. The house mentioned in the book's title provides a good location for the Hardy Boys to keep an eye on things.

Blackwood Hall just sounds like a place where there would be ghostly sightings and unusual paranormal activities, doesn't it? Don't worry, though, Nancy Drew will figure out what's going on.

"The Hidden Staircase" is double the work for Nancy Drew thanks to two mysteries, one involving a haunted house and the other involving her own father. A woman's work is never done.

The Hardy Boys claim "A Figure in Hiding," which tells the story of a glass eye, a dastardly group known as the Goggler Gang, and Frank and Joe's attempt to tie all of the unusual events together.

Nancy's problems could've been solved immediately if she'd had GPS to rely on. Of course, "The Quest of the Missing Map" was written well before GPS was even a thing. The book is entertaining, though!

We know, the idea of a disappearing floor seems pretty preposterous, but the Hardy Boys are taking it quite seriously in the book of the same name. They also work to take down a jewel thief — all in a day's work.

What seems like some innocent pieces of furniture creates a mystery that the Hardy Boys have to untangle. Oh, and there's a tie to Guatemala and a gang of hooligans from little old Bayport as well.

Of course, Nancy Drew has friends who want to go ghost-hunting and — of course — Nancy agrees to go. That IS her schtick, after all. Along the way, they encounter a haunted home, boat and horse. Really!

Nancy Drew lends her sleuthing skills to Madame Alexandra in this title to help her find a missing relative. A secret in the jewel box and an old photo are all Nancy has to help her solve the case.

As commonly done in the Nancy Drew series, "The Mystery at the Moss-Covered Mansion" produces two different storylines — an original (this one written in 1941) and a revision (created 30 years later). Exploding oranges only appear in the 1971 edition, in case you were wondering.

The Hardy Boys must solve a mystery, this time, in the midst of a storm at sea. Clouding the clues are a wallet that appears suddenly and, well, of course, a wailing siren that drives everyone crazy.

You had to figure if the Rocky Mountains were involved, that is probably including some type of camping, which is more suited to Frank and Joe than Nancy. The real crime here involves credit card theft, which sounds a lot more 2019 than 1971.

Nancy Drew finds out she has an imposter in "The Mystery at Lilac Inn," with someone going as far as forging her signature around town. Interesting fact: The original version of this book was reconstructed in the early 1960s to remove potentially racist language.

Frank and Joe must find clues in nature in the Pocono Mountains, including shrieking noises terrifying people during the night. Luckily, the boys encounter a pup who helps them out.

Other than that whole "haunted showboat" thing, we're pretty OK with a storyline that involves a trip to New Orleans and a Mardi Gras party. It won't be any party for Nancy, though, who must put together the clues to solve the case.

Nancy gets a moonstone in the mail from an anonymous sender, a great foreshadowing of what Nancy will go through as the book, "The Moonstone Castle Mystery," proceeds. Of course, it begins by Nancy trying to figure out where the mystery gift came from.

The Hardy Boys are working the crowds at a traveling circus, trying to thwart pickpockets in the act. Whale tattoos are used to eventually help identify the bad guys in this 1968 works.

The Hardy Boys receive the case titled, "While the Clock Ticked," and find themselves dealing with an abandoned house and death threats left to their client in a protected room inside the house. Creepy.

Nancy tags along with her father on a trip to Scotland and, of course, finds herself embroiled in mystery while she's there. Of course, she also gets to meet her great-grandmother, so there's a feel-good moment there.

Nancy Drew tackles strange symbols and rumors that Nancy herself is a witch (what!) in "The Witch Tree Symbol." She manages to escape without being burned at the stake and solves the mystery, too.
