The startled fellow saluted again, and advanced upon his officer. The lieutenant looked up with sudden uneasiness in his eyes. He had gone too far. He had not reckoned upon being dealt with in this summary fashion. He had been bold so long as he conceived himself no more than Cosimo's mouthpiece, obeying orders for the issuing of which Cosimo must answer. Instead, it seemed, the Governor intended that he should answer for them himself. Whatever he now dared, he knew--as Gambara knew--that his men would never dare to disobey the Governor, who was the supreme authority there under the Pope. “My lord,” he exclaimed, “I had my orders from the Captain of Justice.” “And dare you to say that your orders included my messengers and my own self?” thundered the dainty prelate. “Explicitly, my lord,” answered the lieutenant. “It shall be dealt with on my return, and if what you say is proved true, the Captain of Justice shall suffer with yourself for this treason--for that is the offence. Take him away, and someone open me that gate.” There was an end to disobedience, and a moment or two later we stood outside the town, on the bank of the river, which gurgled and flowed away smoothly and mistily in the growing light, between the rows of stalwart poplars that stood like sentinels to guard it. “And now begone,” said Gambara curtly to me, and wheeling my mule I rode for the bridge of boats, crossed it, and set myself to breast the slopes beyond. Midway up I checked and looked back across the wide water. The light had grown quite strong by now, and in the east there was a faint pink flush to herald the approaching sun. Away beyond the river, moving southward, I could just make out the Legate's little cavalcade. And then, for the first time, a question leapt in my mind concerning the litter whose leathern curtains had remained so closely drawn. Whom did it contain? Could it be Giuliana? Had Cosimo spoken the truth when he said that she had gone to Gambara for shelter? A little while ago I had sighed for death and exulted in the chance of expiation and of purging myself of the foulness of sin. And now, at the sudden thought that occurred to me, I fell a prey to an insensate jealousy touching the woman whom I had lately loathed as the cause of my downfall. O, the inconstancy of the human heart, and the eternal battles in such poor natures as mine between the knowledge of right and the desire for wrong! It was in vain that I sought to turn my thoughts to other things; in vain that I cast them back upon my recent condition and my recent resolves; in vain that I remembered the penitence of yestermorn, the confession at Fra Gervasio's knee, and the strong resolve to do penance and make amends by the purity of all my after-life. Vain was it all. I turned my mule about, and still wrestling with my conscience, choking it, I rode down the hill again, and back across the bridge, and then away to the south, to follow Messer Gambara and set an end to doubt.
