As they crossed the bridge to the main part of the castle, Greta saw two women entering the main doorway.
"Look, Anna," she said in great excitement. "Isn't that Princess Ingrid and Princess Louise going into the castle right this minute?"
When Anna looked, the women had disappeared. Greta was now more eager than ever to visit the castle. Maybe she would see her beloved Princess Ingrid again. Would the Princess remember the little girl who had found her handkerchief on the stairs of the Marble Church? Greta wondered. She was anxious to go inside, but Anna stopped in the courtyard to listen to the chimes on the castle tower. Every hour of the day the ringing chimes played a different tune.
"Let's see the Knights' Hall first," suggested Anna, when they went inside.
Greta wanted to say, "Let's follow Princess Ingrid," but she didn't know which way the Princess had gone. So she followed Anna without a word. The Knights' Hall was the largest room Greta had ever seen. The walls were covered with hangings whose colored threads were woven in such a way as to show scenes from Danish history. Greta thought she would like to study history if she could learn it from pictures like these instead of from textbooks. While she was looking at one of the hangings in a far corner of the room, Anna grabbed her arm.
"There they go, Greta. Don't you want to follow them?"
Then Greta remembered that Princess Ingrid was here in the castle. How could she have forgotten? She and Anna and Tante Elsie left the Knights' Hall and entered the long series of drawing-rooms that filled one wing of Frederiksborg. Greta scarcely looked at the paintings that hung on every wall. She wanted to see a real live princess, not a painted lady in a golden frame. They walked slowly through room after room, but not a glimpse of the Princess did they get.
"I guess Princess Ingrid and her sister have left the castle," said Greta, in an unhappy tone. She was ready now to leave it herself, for it held no further interest for her.
"Now for the most wonderful room of all," said Anna, after they had gone through all the drawing-rooms. She almost had to drag Greta to the chapel, which formed an important part of the castle itself. When the royal family lived at Frederiksborg, services were held here every Sunday. This chapel was really as large as a church. As they came in, the organist was playing softly, and Greta sat down to listen to the music, while Anna and her mother went to look at the paintings which were on exhibition in the balcony of the chapel.
