So the poor nobleman thanked the old woman and returned to the palace. Nighttime approached and they gave him a room next to that in which the princesses slept. So he lay on the bed and began to keep watch. Then one of the princesses brought sleeping-drugs in wine and asked him to drink her health. He could not refuse, and so he took the goblet, turned to the wall, and poured it into the bed. At midnight the princesses went to look whether he was asleep or not. Then the poor nobleman pretended to be as sound asleep as a log, and himself kept a keen look out for every noise.
“Now, sisters, our watchman has gone to sleep: it is time we set out on our promenade: it is time.”
So they all put on their best clothes, and the elder sister went to her bedside, moved the bed, and an entrance into the subterranean realm instantly opened up beneath, leading to the home of the Accursed Tsar.
