Who or what is the mysterious organisation known as A.T.A.C.? And how are Frank, Joe and even Fenton Hardy involved? Are the Hardys leaving Bayport forever? How has Laura Hardy's life changed? Why is Aunt Gertrude acting so strange? Where are Lola and Callie? The clues to these questions are uncovered as Frank and Joe take to the skies to crack a diamond-smuggling team of sky-divers and then encounter a young woman whose identity has been stolen - literally! Action, thrills and lots of mystery!
