Rich girl Lindsay Peyton is throwing the biggest and best Sweet Sixteen bash that Bayport has ever seen. But when Frank and Joe discover that her car has been keyed, it looks like someone isn't so happy that Bayport's princess is showing off. Meanwhile, a group calling themselves the Scaredevils is filming themselves committing random mischief around town - including keying Lindsay's car - which threatens the security of Lindsay's big day.

Everyone in Bayport can't wait for the biggest event of the season: the premiere of G-Force - the newest ride by the world-renowned Piperato Brothers. Their creation is going to change the fortunes of Funsport, Bayport's small and recently run-down amusement park. Frank and Joe are friends with Daisy Rodriguez, the owner's daughter, and are first in line for the ride's launch. Purple lights click off, a huge whoosh emanates from the floor, loud music pulses....

Frank and Joe Hardy have been invited to take part in a conservation mission by a marine biologist at the Bayport Aquarium. The boys get to go on an all-expenses-paid trip to the lush and beautiful Florida Keys to help save sharks! But the trip’s purpose is suddenly sidelined when a paddle boarder goes missing, and rumors start that the disappearance is the result of a shark attack. After spending so much time learning about the local shark population, the Hardy Boys aren’t buying the story.

"Joe," I said, concerned, "hit the brake!" "I am," Joe said, pumping the pedal now. But the car didn't slow at all. The traffic light turned red as we hurtled toward the intersection. And suddenly I saw the one other car out this early on a Saturday morning - a huge Express Delivery truck! Joe screamed. I leaned forward, bracing myself against the dashboard. There was nothing we could do. It was speeding right at us!

As I rounded the corner, I spotted Rick just ahead. He paused and bent down to poke at something on the ground by his feet, muttering something that I couldn't make out due to the wind. WHOOSH! I gasped and jumped back as a huge pile of snow slid off the roof of the ski shack, completely burying Rick!

Brother detectives Frank and Joe search a hidden castle for clues to help them find a missing comic book in the 19th book in the thrilling Hardy Boys Adventures series.

"JOE!" Frank suddenly yelled behind me, but it was too late. A dark shape advanced on us from inside the doorway, and a bag was thrown over my head again. I could hear them doing the same to Frank too. Arms reached out and roughly pulled me inside....

First, a priceless painting disappears from the Bayport Historical Museum; then, two ancient samurai swords vanish from a private collection. A string of robberies has hit Bayport, and all signs point to the Phantom, a recently released ex-con who last struck more than 20 years ago. There's only one problem: The Phantom has vanished into thin air, and not even Frank and Joe Hardy can track him down.

Bayport High's Green Environment Conservation Club is camping on Black Bear Mountain. Not only does the mountain live up to its name - the fierce, furry animals are everywhere - but rumor has it that a madman lurks in the nearby forest, and the crazy dude has a penchant for feasting on human flesh. When the campers wake up, however, not only do they find a bear roaming the campsite, but their teacher is missing...and blood is streaked across his tent.

Dear Diary...Bess, George, and I are actually in Alaska! Everywhere you look, there are massive mountains and sparkling, deep-blue waters. We're on the maiden voyage of the Arctic Star luxury cruise ship, and my old friend, Becca Wright, the assistant cruise director, needs our help. She received threatening emails before even setting sail; then a bloody body turned up in the swimming pool.

It does not take much to convince Frank and Joe to be extras in the new zombie movie that's filming in Bayport. Not only do they get a behind-the-scenes glimpse of the magic that goes into making horror movies, but they also get to wear freakishly realistic zombie makeup that makes them look like the walking dead! But the horror gets a little too real when disaster hits the scene.

One of the Hardys’ favorite writers, Nathan Foxwood, has recently died in a tragic car accident. Now, the press is swarming his house in Bayport to get the scoop on the novel he completed just before his untimely death. When Joe hears that Nathan’s wife is having a giant estate sale, he drags Frank with him. Who could pass up the opportunity to see inside their favorite author’s home? Nathan’s wife says she wants to get away as quickly as possible. She’s sure the house is haunted. But Nathan’s assistant, Adam, is not so willing to blame it all on the supernatural.

Frank and Joe are back on Black Bear Mountain, the scene of a previous wilderness adventure and mind-bending mystery. This time, the brothers are checking in on Dr. K, a friend they made during their first trip. Dr. K is a fan of living off the grid, but he’s been MIA long enough to cause worry in the small mountain town. And so the teenage detectives Black Bear Mountain relied on before have been called in to help once again.

Mr. Lakin made his way over to Don Sterling. "It's bad enough we have to suffer through your performances onstage. Now come on, we're going to be late for our own party. The whole world doesn't stop for you, you know." Mr. Lakin gave the Don's boot a kick. The Don didn't move. Joe and I exchanged glances. Something was definitely not right. Joe knelt down and put his fingers on Don Sterling's neck like we'd been taught in our first aid course.

An original Sherlock Holmes manuscript was stolen from the Bayport Museum and now pages keep showing up in Frank and Joe's things: their lockers, menus, even the backseat of their car. It's clear someone is out to frame them. But who could it be? The boys try their usual means of deduction, but everything leads to a dead end. They just keep finding unsuspecting people who were paid to hide the pages by a mysterious third party. Frank recognizes this tactic - it's exactly what Moriarty would do to throw off Sherlock Holmes. So the brothers decide to use one of Sherlock's signature ideas.
