Join Frank and Joe Hardy on their very first mystery adventure in The Tower Treasure! When a daring robbery leaves their friend’s family in dire straits, the Hardy boys take it upon themselves to uncover the truth and clear his name. Their search leads them to hidden clues, suspicious characters, and a mysterious old tower that holds secrets of its own.

Something is not right in Bayport. After a series of unfortunate (yet harmless) pranks, it looks like Frank and Joe have caught their suspect surprisingly early. Their classmate, Seth Diller, has taken his love of filmmaking a bit too far. But shortly after Frank and Joe confront Seth, there are fresh outbreaks of Seth-like pranks. Except these aren't as harmless. After a bit of investigating, the Hardy Boys uncover evidence of the Red Arrow - a group that will stop at nothing to bring chaos and crime to Bayport's peaceful existence.
