Stolen starfish and washed-up water-skis are no match for the quick-thinking Hardy Boys. Team up with Frank and Joe as they investigate three summer-themed mysteries in this Hardy Boys Clue Book paperback bind-up!

A trip to the Tide Town Aquarium turns fishy when Seymour the spotted starfish goes missing from his tank in Sea Life Secrets. Could Seymour have escaped on his own, or has someone—or something—stolen him? With notebook in hand, the Hardy Boys are determined to find out.

In Water-Ski Wipeout, Frank and Joe can’t wait to show off their water-ski skills at Lake Poketoe. But when Joe’s treasured pair of water-skis disappear from the shed, a witness comes forth and gives the boys the key clues they will need to catch the thief.

In Splash Pad Sabotage, Bayport’s brand-new Splash and Dash Pad shuts down after overflowing with foamy bubbles. Frank and Joe must compile a list of suspects to uncover the Bayport Bubbler, or else the splash pad will stay closed for the rest of the summer!
