So the soldier went and stayed with the Tsar, and had a sufficiency of all things, simply rolled in riches, and he thought it was time he should marry. So he married, and one year later God gave him a son. Then this boy fell into such a fearful illness—so terrible that there was nobody who could cure it—and it was beyond the skill of the physicians; there was no understanding of it. The soldier then thought of the old devil and of the undertaking he had given him, and how it had run in the undertaking: “I shall serve you eternally as a faithful servant.” And he thought and said: “What is my old devil doing?”
Suddenly the same old devil appeared in front of him and asked: “What does your worship desire?”
And the soldier answered: “My little boy is very ill. Do you know how to cure him?”
So the devil fumbled in his pocket, got out a glass, poured cold water into it, and put it over the head of the sick child, and told the soldier: “Come here, look into the water.” And the soldier looked at the water; and the devil asked him: “Well, what do you see?”
“I see Death standing at my son’s feet.”
“Well, he is standing at his feet; then he will survive. If Death stands at his head, then he cannot live another day.” So the devil took the glass with the water in it and poured it over the soldier’s son, and in that same minute the son became well.
“Give me this glass,” the soldier said, “and I shall never trouble you for anything more.” And the devil presented him with the glass, and the soldier returned him the undertaking.
Then the soldier became an enchanter, and set about curing the boyárs and the generals. He would go and look at the glass, and instantly he knew who had to die and who should recover. Now, the Tsar himself became ill, and the soldier was called in. So he poured cold water into the glass, put it at the Tsar’s head, and saw that Death was standing at the Tsar’s head.
The soldier said: “Your Imperial Majesty, there is nobody in the world who can cure you. Death is standing at your head, and you have only three hours left of life.”
When the Tsar heard this speech, he was furious with the soldier. “What, what!” he shrieked at him. “You who have cured so many boyárs and generals, cannot do anything for me! I shall instantly have you put to death.”
