In the evening, when the princesses entered their room, Joseph sneaked inside. The doors were then shut and locked up by nine bolts. He noticed that, instead of preparing to go to bed, the princesses began to brush their hair, to dress themselves in beautiful clothes and to put on jewels like they were going to leave somewehere.
Then, the eldest sister stamped her foot on the floor three times and suddenly, a trap door opened. They went down on a secret staircase till they reached a garden whose gates opened when the eldest sister stamped her foot again. Joseph followed them everywhere they went.
