Ever since her sister, Agnes, died, Pearl has a tradition whenever it snows. She makes a person out of snow. A snow sister. It makes Christmas feel a little less lonely.
On Christmas Eve, her father receives a letter about a long-lost relative's will. Is their luck about to change?
Hoping for a better Christmas, Pearl wants to make a Christmas pudding and asks for credit at Mr. Noble's grocery. But she is refused, chased down the street, and hit by a hansom cab. The snow is falling so hard that they can't take her home. She'll have to stay at Flintfield Manor overnight - and in a haunted room!
