_And if I stand here much longer staring they'll notice me and haul me in._ He quickly turned his horses away from the gate and headed back to Ugolini's mansion. * * * * * At the beginning of the third Nocturn, Lorenzo, David, and a servant of Ugolini's named Riccardo, whom they had chosen for his size and strength, emerged from an alley near the north side of the city wall. David wore a hood pulled low over his face. He limped and walked with a stick. Lorenzo had advised against his being out in the street at all, but David had answered that the watch did not know he was in Orvieto and would not be looking for him. Lorenzo was amazed at how rapidly David had gotten better. He had never seen a man walking only two days after taking a bad arrow wound in the leg. The Muslims who taught David the art of healing must be even better than Jewish physicians. As they walked, Lorenzo made David recite the names of half a dozen prominent Perugian merchants who were supporters of King Manfred. If the podesta were to question David about his whereabouts the night of the Filippeschi uprising, these men would bear witness that David and Lorenzo had been in Perugia. "If d'Ucello does question you, how will you explain that you are back in Orvieto without having been seen entering through the gate?" Lorenzo asked him. "I will tell him--with the greatest reluctance--that the line was very long when I arrived and that I was in haste to enter, so I bribed the men on duty to let me by. The more time passes before he discovers my presence in Orvieto, the more believable that will be." "If he suspects you of anything, he will arrest you no matter how good a story you tell him," Lorenzo said. David stopped walking and rested his hand on Lorenzo's shoulder. "That is why you must go tonight, my friend. And come back quickly with an army from Siena." * * * * * Lorenzo had a pack over his shoulder and wore a long traveling cloak. Riccardo carried a coil of rope. Ahead of them was a small stone shed built against the wall, beside one of the round guard towers. Lorenzo was not particularly frightened by the ordeal ahead. He had done enough climbing in his younger days. But he was repelled by the thought that through the large opening in the floor of the little house the people of this quarter dumped, not only their garbage, but also the contents of their chamber pots. They went quietly to the door of the shed. There was a guard in the tower above them, though he would have no reason to watch the garbage chute. Riccardo put a meaty hand on the rough-hewn door. It gave without a struggle. Not even locked, thought Lorenzo. He supposed the podesta, may his ballocks wrinkle up like prunes, had not thought that anyone would choose this ignominious way to escape from the city. "Sophia told me to tell you she would miss you," David said. "Kiss her for me," said Lorenzo.
