The Mystery of the Christmas Thief

Santa looked over the railing and thought he saw a shadow move on the stairwell. He called out, "Rudolph, is that your?", but no one answered. When Santa looked for the shadow again he saw nothing, so he got back to work. Santa had many, many more towns to visit. He had to work fast. But outside one house, Santa felt uneasy again. A cold breeze passed across the back of his neck. Then he thought he heard a crunch of snow behind him. He quickly turned his head around hoping to see what he heard and felt. And like before, there was nothing.
