Daredevils is the 159th title of the Hardy Boys series, written by Franklin W. Dixon.

The Hardy Boys meet popular stunt man and former family friend Terrence McCauley.

After two attacks on Terrence's life, Joe Hardy enters Daredevil fest — a competition to decide the best young stuntman — as a bodyguard to protect Terrence from the stalker.

Then, just when they think they've got the stalker, the mystery man kidnaps their parents and sends them back to square one.

Frank and Joe Hardy finally find out that Slim Billy, a man who Terrence almost blew up, is the one looking for revenge and trying to kill him.
