Mary has so much to do to get prepared for the holidays - and she has a nasty cold on top of it all. But what can she do when an old friend asks for her help? Especially if that old friend is Saint Nick - who is certainly not as jolly as he should be. Not only does Mary need to help Santa solve a mystery that could ruin Christmas - she also needs to help others understand who is Truly Santa.
