The Mysterious Man in White

It's the first snowfall of winter, and Frank and Joe Hardy have built the most awesome snowman. Only one problem: there's a snowman contest in the park, and the snowman is too huge to move.

But when the boys wake up the next day, their snowman is missing. And when they get to the park, they get another surprise: there is their snowman, and he's won first prize -- but someone else is taking credit. Now Frank and Joe have to prove that they made the snowman -- and put the deep freeze on a major phony!
