With one furtive touch of the hand, one long last look, they separated, Faustina to mingle in the crowd, Gouache to follow at a long distance until he saw her kneeling at her chair before one of the side altars of the church. Then he stationed himself where he could see her, and watched through the half hour during which the low mass lasted. He did not know when he should see her again, and indeed it was as likely as not that they should not meet on this side of eternity. Many a gallant young fellow marched out in those days and was picked off by a bullet from a red-shirted volunteer. Gouache, indeed, did not believe that his life was to be cut short so suddenly, and built castles in the air with that careless delight in the future which a man feels who is not at all afraid. But such accidents happened often, and though he might be more lucky than another, it was just as possible that an ounce of lead should put an end to his soldiering, his painting and his courtship within another week. The mere thought was so horrible that his bright nature refused to harbour it, and he gazed on Faustina Montevarchi as she knelt at her devotions, wondering, indeed, what strange chances fate had in store for them both, but never once doubting that she should one day be his. He waited until she passed him in the crowd, and gave him one more look before going away. Then, when he had seen her disappear at the turning of the street, he sprang into his cab and was driven back to the barracks where he must remain on duty all day.

As he descended he was surprised to see Sant' Ilario standing upon the pavement, very pale, and apparently in a bad humour, his overcoat buttoned to his throat, and his hands thrust in the pockets. There was no one in the street, but the sentinel at the doorway, and Giovanni walked quickly up to Gouache as the latter fumbled for the change to pay his driver. Anastase smiled and made a short military salute. Sant' Ilario bowed stiffly and did not extend his hand.

"I tried to find you last night," he said coldly. "You were out. Will you favour me with five minutes' conversation?"

"Willingly," answered the other, looking instinctively at his watch, to be sure that he had time to spare.

Sant' Ilario walked a few yards up the street, before speaking, Gouache keeping close to his side. Then both stopped, and Giovanni turned sharply round and faced his enemy.

"It is unnecessary to enter into any explanations, Monsieur Gouache," he said. "This is a matter which can only end in one way. I presume you will see the propriety of inventing a pretext which may explain our meeting before the world."

Gouache stared at Sant' Ilario in the utmost amazement. When they had last met they had parted on the most friendly terms. He did not understand a word of what his companion was saying.

"Excuse me, prince," he said at length. "I have not the least idea what you mean. As far as I am concerned this meeting is quite accidental. I came here on duty."

Sant' Ilario was somewhat taken aback by the Zouave's polite astonishment. He seemed even more angry than surprised, however; and his black eyebrows bent together fiercely.

"Let us waste no words," he said imperiously. "If I had found you last night, the affair might have been over by this time."
