The following Sunday, Daoud stood at the front of the cathedral, reluctantly hearing Mass, bodies pressing him from all sides. Four of Ugolini's men-at-arms, including the massive Riccardo, stood with Daoud. The little cardinal, required by the etiquette of the Sacred College to attend but made fearful by the rumors of fighting and killing to come, had begged Daoud to come with him and stay near him. The noonday heat together with the heat of packed human flesh turned the interior of the cathedral into an oven. The reek of sweat mixed with the heavy smell of incense rendered the air almost unbreathable.

A gilded screen standing on the altar displayed the miraculous linen cloth of Bolsena, lighted candles massed around it. The pope, at least, had left that to Orvieto. Ugolini was one of six red-robed cardinals, half hidden under their huge, circular red hats, who sat in chairs in a row before the altar. Each one had a cluster of assistants and guards behind him. Cardinal de Verceuil was among them. Daoud recognized him from the rear because he was the tallest of the six.

That meant the Tartars were still in Orvieto. If Lorenzo and the Ghibellino army from Siena arrived in time, there would be a chance to kill the Tartars before they rejoined the pope in Perugia. It was maddening, not knowing what Lorenzo had accomplished or where he was. This was one time he wished Christian armies could move with the speed and decisiveness of Muslims. Or Tartars.

The elderly Cardinal Piacenza, his arms supported by priest-assistants, held up the gold cup of wine which Christians believed, in a sense that Daoud had never been able to understand, to be the blood of Jesus the Messiah. The cathedral was filled with a reverent quiet.

A burst of angry men's voices from the rear of the cathedral broke the silence. Shouts echoed against the heavy stone walls. Daoud heard thuds, scuffling, the clash of steel. A jolt of alarm went through him, and his hand went to his sword.

Everyone, including Piacenza, turned to stare. The last time there had been a clash of arms in the cathedral it had been the Count de Gobignon and that heretic preacher, Daoud thought.

Daoud was amazed that Christians would interrupt the most sacred moment of their Mass. He tried to see over the heads of the people around him. One voice, roaring in protest, was raised over the others. It sounded familiar to Daoud.

People were passing word back from the middle of the nave, where the struggle was. "It is Marco di Filippeschi," a man near Daoud cried. "They have come to kill him."

Daoud's body went cold. Might whoever was coming after Marco attack him too?
