"Ugolini. David of Trebizond. And Sophia, at the very least, must have known the reason, or she would not agree to let Rachel go to the brothel. If Sophia knew so much, then perhaps—I say perhaps—she knew more about Ugolini and David and their dealings than she admitted to you. I keep thinking of that night at the Palazzo Monaldeschi when she drew you to the atrium, conveniently for David of Trebizond, who was goading the Tartars into publicly embarrassing themselves. Was she as uninvolved then as she led you to believe?"

Each of Friar Mathieu's sentences was another dagger blow, plunging deep into Simon, sending agony through him, the sharp point searching out his heart.

Friar Mathieu was proceeding in the same painstaking way he had probed Alain's body until he discovered what killed him. Alain, whose murderer had never been found, who had died outside Ugolini's mansion.

Alain! Oh, my God! Could she have known how he was killed?

What had really been happening at Ugolini's mansion?

Simon bent double, digging his fingers into his skull. His head might burst apart if he did not hold it tightly. Could all the love he thought he had found in her be a lie? Could she be an enemy?

"You are destroying my life," he muttered, his hands over his face.

He felt the light touch of the old man's hand on his shoulder. "When a leg wound festers, the surgeon has to cut the leg off to save the man's life."

And the old soldiers tell me the man always dies anyway, Simon thought bitterly.

"I am doing this not just for you, Simon," Friar Mathieu went on. "There was a secret war being waged in Orvieto to prevent us from allying ourselves with the Tartars. The person behind it was probably King Manfred of Sicily, who wants to keep Charles d'Anjou out of Italy. Ugolini was Manfred's agent. And Sophia may have been Ugolini's weapon against you."
