In this literary debut of the adventure series, teenage aspiring detectives Frank and Joe Hardy stumble onto a crime spree that touches every corner of their hometown of Bayport. With the help of their father, legendary detective Fenton Hardy, Frank and Joe encounter thieves, robberies, bomb threats, frame-ups, and a hidden cache of loot in a quest to crack the case and earn their reward. This is a reprint of the 1927 first edition of The Hardy Boys: The Tower Treasure, without cuts or censorship, as originally written by Leslie McFarlane under the pen name Franklin W. Dixon.
