Danger on Parade (Nancy Drew Files #77) by Carolyn Keene - Vintage Paperback

A New York holiday tradition draws Nancy into a march of crimes...

Nancy and Bless have been offered the chance of a lifetime a behind-the-scenes look at Mitchell's department store's star-studded Thanksgiving Day parade. But this year's gala event is following a perilous route. Someone is determined to flatten the floats, burst the balloons, and sabotage the entire spectacle- no matter who gets hurt.

The Thanksgiving feast of felonies leaves a sour taste in Nancy's mouth. She's leamed that the police already have a prime suspect-Bess-and they have evidence to back up their charge. Nancy knows she'll have to work fast: Not only could the parade be headed for disaster, but her best friend could be headed for jail!
