The Great Airport Mystery (The Hardy Boys Book 9)

A routine trip to visit the new hometown airport turns into a high-flying race against danger for the Hardy Boys!

Frank and Joe Hardy are excited to see the new mail planes landing near Bayport, until an out-of-control aircraft nearly crashes right on top of them!

Their quick thinking saves their lives...but not the plane. And the angry airmail pilot, Giles Ducroy, blames the Hardy boys for his crash! Worse, the boys soon discover Ducroy has fallen in with two shady crooks, Ollie Jacobs and Newt Pipps, who are plotting something big. Their mysterious scheme might strike right at the heart of Bayport's booming airmail business.

Frank and Joe do know one thing: Ducroy hasn't forgiven them for the crash that resulted in his being dismissed from the airmail service. With their famous detective father, Fenton Hardy, tied up on another case, it's up to the brothers to uncover the truth.

Now the Hardy boys must investigate secret meetings and circumstantial evidence that points to them, all while staying one step ahead of the men who want them out of the way. With clues in the sky and danger on the ground, this mystery is packed with Hardy-style action, bravery, and clever detective work.

Can Frank and Joe crack the case before the thieves take flight? Strap in, because adventure is about to take off!
