Claude said nothing, but he rose with burning cheeks, paid his share--it was seven o'clock--and, passing out, made his way back. It should be said that in addition to the Tertasse Gate, two lesser gates, the Treille on the one hand and the Monnaye on the other, led from the town proper to the Corraterie; and this time he chose to go out by the Treille. Having ascertained that the guard-room there also was almost denuded of men, he passed along the Corraterie to his bastion, hugging the houses on his right, and giving the wall a wide berth. Although the cold wind blew in his face he paused several times to listen, nor did he enter his bastion until he had patiently made certain that it was untenanted. The night was very dark: it was the night of December the 12th, old style, the longest and deadest of the year. Far below him in the black abyss on which the wall looked down, a few oil lamps marked the island and the town beyond the Rhone. Behind him, on his left, a glimmer escaping here and there from the upper windows marked the line of the Corraterie, of which the width is greatest at the end farthest from the river. Near the far extremity of the rampart a bright light marked the Porte Neuve, distant about two hundred yards from his post, and about seventy or eighty from the Porte Tertasse, the inner gate which corresponded with it. Straight from him to the Porte Neuve ran the rampart a few feet high on the inner side, some thirty feet high on the outer, but shrouded for the present in a black gloom that defied his keenest vision. He waited more than an hour, his ears on the alert. At the end of that time, he drew a deep breath of relief. A step that might have been the step of a sentry pacing the rampart, and now pausing, now moving on, began to approach him. It came on, paused, came on, paused--this time close at hand. Two or three dull sounds followed, then the sharper noise of a falling stone. Immediately the foot of the sentry, if sentry it was, began to retreat. Claude drove his nails into the palms of his hands and waited, waited through an eternity, waited until the retreating foot had almost reached, as he judged, the Porte Tertasse. Then he stole out, groped his way to the wall, and passed his hand along the outer side until he came to the nail. He found it. It had been made secure, and from it depended a thin string. He set to work at once to draw up the string. There was a small weight attached to it, which rose slowly until it reached his hand. It was a stone about as large as the fist, and of a whitish colour. CHAPTER XXIII. IN TWO CHARACTERS. After the wave, the trough of the wave; after action, passion. Not to sink a little after rising to the pitch of self-sacrifice, not to shed, when the deed is done, some bitter tears of regret and self-pity, were to be cast in a mould above the human.
