Daoud awaited Ugolini's coming, and the message he bore, as a man accused of a capital crime awaits the verdict of his judge.

And if it was true that Fra Tomasso had irrevocably turned against them? Daoud must begin all over again with a new plan to stop the alliance.

The fire gave off the sour odor of strange substances Ugolini had previously burned on the hearth. Daoud pushed himself out of the cardinal's chair and went to get a breath of fresh air. He opened the casement window and saw Ugolini's sedan chair, borne by four servants, turning in toward the door of the mansion.

The cardinal's chair passed the shop across the street, where rows of large and small pots, brightly painted with floral designs, were laid out on a large blanket. The potter and his wife, bundled up in heavy cloaks, were calling out for the cardinal's blessing. Daoud saw a tiny hand emerge from the curtains of the sedan chair, closed against the February cold. The hand shaped the sign of the cross in the air as the shopkeepers fell to their knees.

Daoud wondered whether the potter and his wife felt they had an unlucky spot to offer their wares. That was where, last August, de Verceuil's archers had shot down two men in the crowd when the Tartars were entering the city. And it was in front of that shop, shuttered then for the night, that Alain de Pirenne's body had been found. Had the shopkeeper or his wife seen anything, and were they keeping silent only out of fear? Months had gone by, but the podesta, d'Ucello, was still investigating the killing, questioning and requestioning everyone who might know something about it.

Daoud paced the room anxiously until Ugolini came in, throwing his fur-trimmed cape and his wide-brimmed red hat to a servant. He sat down in the chair Daoud had been using. Daoud closed the door.

As a man dying of thirst begs for water, Daoud prayed for good news.

But Ugolini's pale face, haggard eyes, and downturned mouth told a different tale. Daoud's heart plunged into despair.

"Has he turned against us?" He hated the note of pleading he heard in his voice.

Ugolini went to his worktable, sighed, and sat down heavily. His eyes seemed to be crossed, staring down his pointed nose at the painted skull that grinned back at him. His restless fingers found the dioptra lying on the table, and he started to roll the brass tube in his hand.
