Whatever Louis decided must be right. But, dear God, let him not decide to cast away the alliance.

Louis said, "Urban grants the thing I want most in the world, but only if I agree to that which I desire least. And I do not want to give in to him."

Oh, God! The sky seemed to darken.

"What does he ask you to do, Sire?"

Louis sighed, a deep, tremulous expulsion of breath. "He asks that the might of France should be diverted into a squabble among petty princes in Italy, when Jerusalem is at stake!"

It seems more than a squabble when you are in the thick of it, thought Simon, remembering the night the Filippeschi had attacked the Monaldeschi palace.

"I cannot wait any longer to begin preparing for a crusade," Louis said. "I want to return to Outremer in six years, in 1270. That may seem to you a long time away, but for such a great undertaking as this it is barely enough. It took me four years to get ready for the last crusade, to gather the men and supplies, and it will be harder this time."

"Why 1270, Sire?" said Simon.

Louis's head drooped and his eyes fell. "To win my freedom I promised Baibars, the Mameluke leader who is now Sultan of Cairo, that I would not wage war on Islam for twenty years."

"An oath to an unbeliever—" said Simon.
