Hardy Boys Adventures Collection Volume 10

Dungeons & Detectives:
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.
Frank and Joe have been hanging out at Sir Robert's Comic Kingdom, the local comic and gaming shop, and got the exclusive invite to this year's Halloween costume ball at Bayport's one and only castle. Sir Robert plans to use the big event to unveil his most prized possession, a super rare comic that is rumored to contain a map to buried treasure.
Sir Robert agrees to show his store regulars - who now include Frank and Joe - a sneak preview of the comic before the party. But when he goes to unlock the fireproof casing, he finds the book is gone.
It will take all of Frank and Joe's recently acquired LARPing skills to solve this case. Anything can happen in a castle full of dungeons and deception. Can the Hardy boys keep up?
Return to Black Bear Mountain:
Brother detectives Frank and Joe face the dangers of Black Bear Mountain once again in the 20th book in the thrilling Hardy Boys Adventures series.
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.
It's not a good start to the investigation when Frank and Joe's ATV is put out of commission by a falling tree. Then their camp, including their radio - their only way to contact the outside world - is destroyed by wildlife searching for food. And when they finally reach Dr. K's research station, they find his cabin has been cleaned out and abandoned - the only current resident is an angry skunk.
Frank and Joe may have been better prepared for their second Black Bear Mountain adventure, but they're not having any more luck this time around. In fact, they've been downright unlucky. Is someone trying to sabotage their mission? And if they are, how can the brothers stop this invisible foe?
