Tower Treasure

The book that started it all. When a dying criminal's final confession points to hidden loot in an abandoned tower, teenage brothers Frank and Joe Hardy embark on what should be a straightforward treasure hunt. But nothing in Bayport is ever simple. The boys quickly discover the treasure is tied to something far bigger than money, something that threatens to destroy their family's reputation. With suspects multiplying and danger closing in, the Hardy brothers must piece together cryptic clues before the truth remains buried forever. This is the mystery that launched one of the most beloved juvenile series in history, establishing the formula generations of readers would return to: two brave brothers, one impossible puzzle, and the unshakable belief that justice always prevails.
