Bending her head coldly she drew away her hand. At that moment, as I lifted my eyes, I saw something which for an instant rooted me to the spot with astonishment. In the entrance of the passage which led to the Rue St. Denys two people were standing, watching us. The one was Simon Fleix, and the other, a masked woman, a trifle below the middle height, and clad in a riding-coat, was Mademoiselle de la Vire!

I knew her in a moment. But the relief I experienced on seeing her safe and in Blois was not unmixed with annoyance that Simon Fleix should have been so imprudent as to parade her unnecessarily in the street. I felt something of confusion also on my own account; for I could not tell how long she and her escort had been watching me. And these two feelings were augmented when, after turning to pay a final salute to Madame de Bruhl, I looked again towards the passage and discovered that mademoiselle and her squire were gone.

Impatient as I was, I would not seem to leave madame rudely or without feeling, after the consideration she had shown me in her own sorrow; and accordingly I waited uncovered until she disappeared within the 'Little Sisters.' Then I started eagerly towards my lodging, thinking I might yet overtake mademoiselle before she entered. I was destined to meet, however, with another though very pertinent hindrance. As I passed from the Rue St. Denys into the quiet of my street I heard a voice calling my name, and, looking back, saw M. de Rambouillet's equerry, a man deep in his confidence, running after me. He brought a message from his master, which he begged me to consider of the first importance.

'The Marquis would not trust it to writing, sir,' he continued, drawing me aside into a corner where we were conveniently retired, 'but he made me learn it by heart. "Tell M. de Marsac," said he, "that that which he was left in Blois to do must be done quickly, or not at all. There is something afoot in the other camp, I am not sure what. But now is the time to knock in the nail. I know his zeal, and I depend upon him."

An hour before I should have listened to this message with serious doubts and misgivings. Now, acquainted with mademoiselle's arrival, I returned M. de Rambouillet an answer in the same strain, and parting civilly from Bertram, who was a man I much esteemed, I hastened on to my lodgings, exulting in the thought that the hour and the woman were come at last, and that before the dawn of another day I might hope, all being well, to accomplish with honour to myself and advantage to others the commission which M. de Rosny had entrusted to me.

I must not deny that, mingled with this, was some excitement at the prospect of seeing mademoiselle again. I strove to conjure up before me as I mounted the stairs the exact expression of her face as I had last seen it bending from the window at Rosny; to the end that I might have some guide for my future conduct, and might be less likely to fall into the snare of a young girl's coquetry. But I could come now, as then, to no satisfactory or safe conclusion, and only felt anew the vexation I had experienced on losing the velvet knot, which she had given me on that occasion.

I knocked at the door of the rooms which I had reserved for her, and which were on the floor below my own; but I got no answer. Supposing that Simon had taken her upstairs, I mounted quickly, not doubting I should find her there. Judge of my surprise and dismay when I found that room also empty, save for the lackey, whom M. de Rambouillet had lent me!

'Where are they?' I asked the man, speaking sharply, and standing with my hand on the door.

'The lady and her woman, sir?' he answered, coming forward.

'Yes, yes!' I cried impatiently, a sudden fear at my heart.
