She hesitated for a moment; then she turned and followed him slowly. He went before her, wrapped in his supreme indifference, through the Porta Basilica, and came out into the blaze of the sunshine. As she emerged, she saw him standing quite still. He seemed—she was just behind him—to be staring at a very fair woman who, accompanied by a guide, was coming towards the church. Mrs. Clarke, intent on the Bedouin, was aware of this woman’s approach, but felt no sort of interest in her until she was quite close; then something, some dagger-thrust of the mind, coming from the woman, pierced Mrs. Clarke’s indifference.

She looked up and met the sad, pure eyes of Rosamund Leith.

For a moment she stood perfectly still gazing into those eyes.

Rosamund had stopped, but she made no gesture of recognition and did not open her lips. She only looked at Mrs. Clarke, and as she looked a deep flush slowly spread over her face and down to her throat.

The Greek guide said something to her; she moved, lowered her eyes and went on into the church without looking back.

The Bedouin strode slowly away into the blaze of the sunshine.

Mrs. Clarke remained where she was, motionless. For the first time perhaps in her life she was utterly amazed by an event. Rosamund Leith here in Constantinople! What did that mean?

Mrs. Clarke knew the arrival of Rosamund meant something that might be tremendously important to herself. As she stood there before the church she was groping to find this something; but her mental faculties seemed to be paralyzed, and she could not find it. Rosamund Leith’s eyes had told Mrs. Clarke something, that Rosamund knew of Dion’s unfaithfulness and who the woman was. What did the fact of Rosamund’s coming to Constantinople in possession of that knowledge mean?

From the minaret above her head the muezzin in a piercing and nasal voice began the call to prayer. His cry seemed to tear its way through Mrs. Clarke’s inertia. Abruptly she was in full possession of her faculties. That Eastern man up there, nearer to the blue than she was, cried, “Come to prayer!” But she had already uttered her prayer, and surely Rosamund Leith was the answer.

As she drove away towards the Golden Horn she passed the Bedouin striding along in the sun.
