None of the devices were too obviously used, but at length Henriot picked up so many forgotten articles, and heard so many significant phrases, casually let fall, that he began to feel like the villain in a machine-made play, where the hero for ever drops clues his enemy is intended to discover. Introduction followed inevitably. "My aunt can tell you; she knows Arabic perfectly." He had been discussing the meaning of some local name or other with a neighbour after dinner, and Vance had joined them. The neighbour moved away; these two were left standing alone, and he accepted a cigarette from the other's case. There was a rustle of skirts behind them. "Here she comes," said Vance; "you will let me introduce you." He did not ask for Henriot's name; he had already taken the trouble to find it out--another little betrayal, and another clue. It was in a secluded corner of the great hall, and Henriot turned to see the woman's stately figure coming towards them across the thick carpet that deadened her footsteps. She came sailing up, her black eyes fixed upon his face. Very erect, head upright, shoulders almost squared, she moved wonderfully well; there was dignity and power in her walk. She was dressed in black, and her face was like the night. He found it impossible to say what lent her this air of impressiveness and solemnity that was almost majestic. But there _was_ this touch of darkness and of power in the way she came that made him think of some sphinx-like figure of stone, some idol motionless in all its parts but moving as a whole, and gliding across--sand. Beneath those level lids her eyes stared hard at him. And a faint sensation of distress stirred in him deep, deep down. Where had he seen those eyes before? He bowed, as she joined them, and Vance led the way to the armchairs in a corner of the lounge. The meeting, as the talk that followed, he felt, were all part of a preconceived plan. It had happened before. The woman, that is, was familiar to him--to some part of his being that had dropped stitches of old, old memory.
