Detective brothers Frank and Joe work to debunk a time travel machine in the eighth book in the interactive Hardy Boys Clue Book series.
Bayport Elementary is almost ready for the annual science fairâitâs all down to the final touches. Frank and Joe have collaborated on a detective helmet. Itâs the perfect lie detectorâjust place it on a suspectâs head and the bells and whistles will tell you when theyâre lying.
But not everyone is as prepared for the big fair. Their good friend Phil has designed a time machine he calls the Time Warp Wonder. He just needs to figure out how it works firstâŚ
Phil uses Chetâs hamster as a test subject. And the machine really does make the hamster disappear from the cafeteria! Itâs just that Phil isnât sure where the hamster went or how to get him back. Frank and Joe are not so sure the hamster went back in time. They have a feeling their Clue Book will be more help to Chetâs hamster than Philâs calculations.
But the brothers start questioning their instincts when they receive pictures of the hamster in different time periods; dressed as caveman with the dinosaurs, suited up in armor in the middle ages, in a top hat watching Abe Lincoln give a speech. Could Chetâs hamster really be traveling though time? Itâs up to the Hardy Boysâand youâto find out!
