The Clue That Flew Away (The New Bobbsey Twins #3)

Blurb

It's a dream come true for Flossie when she's given a part in a new movie. But there's trouble on the set: the fabulous Armstrong Flyer, a tiny balloon made of gold and jewels, has been stolen - and teen star Tim Archer is accused of taking it. Nan is sure he's innocent, so who did steal the treasure? The Bobbsey twins think they have the answer - but only one of them knows about the clue that flew away!
