The tower treasure - Franklin W Dixon (The Hardy Boys #1)

Goodreads 3.92

The first of an enduring series.

The Hardy Boys will soon celebrate their 100th anniversary, but they remain the quintessential mystery and detective stories for young readers. This first one, "The Tower Mystery," introduced the action, mystery, and suspense themes. The boys continue to deliver thrills to this day.

It all starts with the boys, Frank and Joe, on their motorcycles delivering important papers to a lawyer in Willowville for their father, Fenton Hardy. He's the well-known private investigator in Bayport. A reckless driver almost forces them over the embankment. It is not long before they find that their friend Chet's yellow jalopy has been stolen, possibly by the same red-haired driver! Stolen loot may be the issue. Later a dying criminal confesses that the loot has been stashed "in the tower" and the Hardy Boys make an astonishing discovery.
