"No, I don't. Please tell me, Anna."

"According to an old, old story, Holger the Dane sleeps in the dungeon that is deep below this tower. If Denmark is ever in trouble of any kind, he will awake and come to her rescue."

"I've heard of Holger the Dane, of course," said Greta, "but I thought he was just an imaginary person."

"He's no more imaginary than a Nisse," said Anna, with a twinkle in her eye.

Greta hated to leave Kronborg, but when Anna told her that they were going to see even finer castles than this one, she was willing to go. After driving about fifteen miles, they turned off the main road and drove down a long avenue of beech trees. At the end of this avenue there was a large white building, with a four-cornered tower rising from the center.

"This is Fredensborg Palace, where the King and Queen live in the autumn," said Anna. "The King comes here for the hunting season."

"Can we go inside this palace?" asked Greta. "I would love to see the Queen's own room."

"Of course you would, little Margrete," said Tante Elsie. "We will ask the guide to show us the Queen's apartments."

It seemed to Greta that the guide took them through miles and miles of rooms. Even then, he showed them only a part of the two hundred and seventy rooms. The palace was much larger than it looked from the front, for it was very long.

"Surely this isn't the Queen's room," said Greta, as she stood in the doorway of the large, sunny bedroom.
