XVII
The beauty of Orvieto, Simon thought, was that, isolated as it was on its great rock, it was as big as it ever could be—and a man could go anywhere in the city quickly on foot. Those of wealth and rank often rode, but a horse or a sedan chair was a mark of distinction rather than a necessity. A bird looking down on the city would see a roughly oval shape, longer from east to west. One might get lost in the twisting side streets but otherwise could walk along the Corso from one end of Orvieto to the other while less than half the sand trickled through an hour glass. From Ugolini's mansion on the south side of the town, Simon reached the Palazzo Monaldeschi, near the northern wall, so quickly, he barely had time to think over the events of the day.
David of Trebizond was a trader, after all, and traders needed armed men to protect their caravans. Why worry about the three men with swords and crossbows he had seen with Giancarlo? They were far from being an army.
But was David actually sending out any caravans?
If I could put someone in the enemy camp ...
Before entering the Palazzo Monaldeschi, he surveyed it with a knight's eye. It was a three-story brown stone building with a flat roof crowned by square battlements. In each of the four corners of the palace there were small turrets with slotted windows for archers. Above the third story rose a block-shaped central tower.
Even as he looked up, he noticed a figure on the battlements, a helmeted man with a crossbow on his shoulder. He looked down at Simon, touched his hand to his helmet, and walked on.
It was good to know that the Monaldeschi family maintained a constant guard on their palace. The hidden enemy of the Tartars could get at them here only by a full-scale siege.
Simon walked around the building. If there were two archers in each turret, their overlapping fields of fire would cover every possible approach. He noted that the piazza in front of the palace and the broad streets on the other three sides allowed attackers no cover. The city wall was nearby, though, he saw. Archers could fire on the Monaldeschi roof from there, and at least two of the city's defensive towers were so close that stone casters set up in them could score hits on the palace.
What if the enemy were to attempt a siege?
