In the front of the book Hans Christian Andersen had written a beautiful poem about Vosborg. It was no wonder that Mr. Christianson treasured this book, for Andersen is the most famous writer of all Denmark. Children all over the world love his fairy tales. "It's getting late, Greta, and I think we should--" began Anna and then stopped. A long, low moan cut through the stillness of the room. It seemed to come from quite near. "What--what was that?" asked Greta. "Oh, I suppose that was Lady Margaret," explained Mr. Christianson. "About a hundred years ago she was kept a prisoner in this room for many years, and every now and then we hear her moaning." "Did you ever see her?" asked Anna. "Well, no, I never did. But whenever we hear that low moan from this room we know it is Lady Margaret." "Doesn't it frighten you?" asked Greta. "Oh, no. We are quite used to it." "This is really a haunted castle, isn't it?" asked Anna. "Every castle in Denmark has at least _one_ ghost, Anna." All the way home the girls talked about the ghost of Lady Margaret. Anna was beginning to think that maybe there really _were_ such things as ghosts and Nisser. When they reached the house, Hans was just getting out of his boat. "Did you get any fish, Hans?" called Anna. "No luck today, Anna." "Are you sure you were trying to catch fish?" asked Greta, in her most teasing manner. "What do you mean by that, Greta?" "I thought maybe you had decided to go after books instead." Anna looked at Hans. Could he have been playing a joke on them at Vosborg? Was it Hans who had taken the book and then put it back? But how could he have gotten into the library? And anyway, she and Greta had both seen him start down the river in the opposite direction. Just then Greta's mother called from the door. "Anna, you have a letter from your mother." "It's too bad you didn't take Chouse with you today, Greta," said Hans, when Anna had gone into the house. "Why? What happened?" "He was naughtier than he's ever been before. He chased the young turkeys all over the place and injured three or four of them." "Did Father see him?" "Yes. He came along just as Chouse caught one of the turkeys and he was terribly angry. You know how proud Father is of those turkeys." "Oh, Hans, what _am_ I going to do?" sobbed Greta. "We can't seem to break Chouse of his awful habit of chasing things. And yet I can't bear to part with him." Just then Anna came running out of the house. "Greta, I have the grandest news. Mother wants you to come to Copenhagen with me when I go home." For a moment Greta forgot her worries about Chouse. "Oh, Anna, that will be wonderful. Let's ask Mother if I may go." CHAPTER IX CHOUSE SEEKS THE SPOTLIGHT It was soon decided that Greta would go back to Copenhagen with Anna. At dinner that evening the girls talked about nothing else, for Greta had never been in Copenhagen before.
