#110 The Secret of Sigma Seven
The Hardys take a leap toward the future -- and plunge into disaster!
The war of the worlds is at hand -- and Bayport is the battlefield!
-
The aliens are invading! No, they're not from another galaxy. They're not even from Mars. They're from Hollywood! A science fiction convention has come to Bayport, and movie director Simon Devoreaux has lost his billion-dollar baby: the film of his latest blockbuster has dematerialized before his eyes!
Frank and Joe are on the case and on the spot. They investigate a world of science fiction and fantasy, but the action is dangerously real. The thief is a master of disguise and diversion -- a formidable enemy who has turned his super high-tech arsenal on the Hardys!
