Real Elves by Helen Smith

This is another Emily Castles short story.  I like the character of Emily.  This time she has volunteered to help at Santa's grotto.

I thought this story was very sweet, but after finishing it, it was nagging me that I'd read it before.  The ending seemed so familiar.  As it turns out, it was similar to a real-life story, so at least I'd solved a mystery as well as Emily.
