What would you have said?

I just read a wonderful example of someone thinking quickly on his feet and I would like to share it with you in the form of a question.

Louis XIV was a believer in astrology. One of his courtiers used horoscopes to predict the death of someone at court and turned out to be correct. The King was afraid that someone with that kind of power might undermine his control, so he decided to have the courtier killed. He had the man brought before him and said something to the effect of, “I see you are a master of astrology. Tell me what fate befalls you and when it will happen.”

The courtier not only guessed what the King was planning but managed to save his life. What might he have answered?
