Then back to his mind, as by flashes of mental lightning, came one by one the reasons which he had forged for not seeing Helena, but they were all of no avail. In vain did he ask himself what he was to say to her, how he was to account for his past silence, and what explanation he was to give of his present flight. There was no answer to these questions, yet all the same an irresistible impulse seemed to draw him up to Helena’s side. He must see her again, no matter at what risk. He must take her in his arms once more, no matter at what cost. "I must, I must," he continued to say to himself, while the same animal instinct which had carried him away from the Citadel on the night of the crime was now carrying him back to it. Almost before his mind had time to tell him where he was going he found himself ascending the hill that leads up to the Bab-el-Gedid. The sight of the gate of the Citadel suggested fresh considerations that might have acted as warnings, but he paid no heed to them. It was nothing to him in his present mood that he was like a man who was putting his head into a noose, walking deliberately into a trap, marching straight into the camp of the enemy whose first interest it was to destroy him. The image of Helena and the sense of her presence so near to him left little else to think about. The gate was still open, for it was not yet twelve o’clock, and in deference to the ritual of the Moslem faith, the muezzin, who lived outside the walls, was permitted to pass through that he might chant the midnight call to prayers from the minaret of the mosque inside the fortress. "Goin’ to sing ’is bloomin’ song, I suppose," thought the sentry, a private of a Middlesex regiment, when Gordon, as one having authority, walked boldly through the gateway. Being now within the Citadel, Gordon began to be besieged by thoughts of the trackers, who would surely keep watch upon the General’s house also if, as Hafiz had said, there was a suspicion that Helena and he intended to go away together. But again the vision of Helena rose before him, and all other considerations were swept away. "To leave Cairo while Helena remains in it would be cowardly," he told himself; and emboldened by this thought he walked fearlessly across the square of the mosque and round the old arsenal to the gate of the General’s house without caring whom he met there. He met no one. The gate was standing wide open, and the door of the house, when he came to it, was open also, and there was nobody anywhere about. With a gathering sense of shame, such as he had never felt before, he stood there for a moment, wondering what course he ought to take, whether to ring for a servant or to walk through as he had been wont to do before the dread events befell. Suddenly the walls of the house within resounded to a peal of raucous laughter, followed by a burst of noisy voices in coarse and clamorous talk.
