Tower Treasure (Version 2)

Frank and Joe Hardy are just ordinary teenagers when they're not solving crimes. Their father is Fenton Hardy, one of America's most famous detectives, and the boys have inherited his relentless instinct for the hunt. When a dying criminal confesses that his stolen loot lies 'in the tower,' the case seems closed, until it becomes clear that both towers of the mansion have already been searched. The police are stumped. The trail has gone cold. But Frank and Joe know there's something everyone missed. What follows is a classic puzzle of clues, dead ends, and one brilliant deduction that cracks the case wide open. Published in 1927, Tower Treasure launched a century-long phenomenon, establishing the template for every teenage mystery series that followed. It's pure, wholesome adventure: two brothers, their trusted circle of friends, and a world where intelligence and courage always win the day. For readers who grew up with Nancy Drew, the Boxcar Children, or any mystery-loving kid who ever picked up a flashlight and whispered 'let's investigate.'
