'Mademoiselle,' I said in a low voice, 'Mademoiselle de la Vire! I have the honour----'

She would not turn, and I stopped. Clearly she heard, but she betrayed that she did so only by drawing her cloak more closely round her. Primed by my respect for the king, I touched her lightly on the shoulder. 'Mademoiselle!' I said impatiently, 'you are not aware of it, but----'

She shook herself free from my hand with so rude a gesture that I broke off, and stood gaping foolishly at her. The king smiled, and nodding to me to step back a pace, took the task on himself. 'Mademoiselle,' he said with dignity, 'I am not accustomed----'

His voice had a magical effect. Before he could add another word she sprang up as if she had been struck, and faced us, a cry of alarm on her lips. Simultaneously we both cried out too, for it was not mademoiselle at all. The woman who confronted us, her hand on her mask, her eyes glittering through the slits, was of a taller and fuller figure. We stared at her. Then a lock of bright golden hair which had escaped from the hood of her cloak gave us the clue. 'Madame!' the king cried.

'Madame de Bruhl!' I echoed, my astonishment greater than his.

Seeing herself known, she began with trembling fingers to undo the fastenings of her mask; but the king, who had hitherto displayed a trustfulness I had not expected in him, had taken alarm at sight of her, as at a thing unlocked for, and of which I had not warned him. 'How is this?' he said harshly, drawing back a pace from her and regarding me with anger and distrust. 'Is this some pretty arrangement of yours, sir? Am I an intruder at an assignation, or is this a trap with M. de Bruhl in the background? Answer, sirrah!' he continued, working himself rapidly into a passion. 'Which am I to understand is the case?'

'Neither, sire,' I answered with as much dignity as I could assume, utterly surprised and mystified as I was by Madame's presence. 'Your Majesty wrongs Madame de Bruhl as much by the one suspicion as you injure me by the other. I am equally in the dark with you, sire, and as little expected to see madame here.'

'I came, sire,' she said proudly, addressing herself to the king, and ignoring me, 'out of no love to M. de Marsac, but as any person bearing a message to him might come. Nor can you, sire,' she added with spirit, 'feel half as much surprise at seeing me here, as I at seeing your Majesty.'

'I can believe that,' the king answered drily. 'I would you had not seen me.'

'The King of France is seen only when he chooses,' she replied, curtseying to the ground.
