Nancy Drew and The Clue Crew get to go on a ski trip with George’s family in Ski School Sneak by Carolyn Keene. Mount Fun Ski Lodge is having a “kids half off weekend” for the first time ever and it’s a big hit. None of the girls know how to ski but Mount Fun has bunny slopes with ski classes and whoever does the best and picks up on it the quickest gets an award. Bess is a natural at it and by lunch time that award is hers. Everyone is happy for her except for one boy who thinks he should have won and thought he had it in the bag. He wins at everything.

All the kids get called into the lodge for lunch and a well needed break. Everyone is starving after skiing all morning long. Sitting next to the girls is a teenager that can do nothing but complain about being drug out to Mount Fun. After having a meltdown, she stomps off to the restrooms. The girls can’t understand why she is so grumpy and who could not have a good time at Mount Fun of all places? Either way, they’re glad she’s gone so they don’t have to listen to her anymore.

After lunch, everyone heads back out to get their gear back on and hit the slopes again. The Clue Crew wants to get as much skiing in as possible before they have to go home since they aren’t staying the night. There’s just one problem; the storage shed is in shambles. Someone seems to have broken into it and trashed the equipment. Nancy starts looking for clues but unfortunately, all the clues point to Bess! Nancy knows that she couldn’t have and wouldn’t have done it but how can she prove it?

In the shed, everyone’s things are strewn about except for Bess’s. Once everyone claims their things and the pile of stuff is picked up a mangled blue mitten is found. Bess is happy when her mitten is returned but when she is told where it was found and directly accused of the vandalism she doesn’t know what to do. All the kids at Mount Fun Ski Lodge think that Bess did it. Nancy and George both know that though the evidence may say otherwise, there is no way Bess could have. Now they must race the clock to clear Bess’s name.
