The Rue de Valois, to which a tradesman, who was peering cautiously out of his shop, directed me, proved to be one of the main streets of the city, narrow and dirty, and darkened by overhanging eaves and signboards, but full of noise and bustle. One end of it opened on the parvis of the Cathedral; the other and quieter end appeared to abut on the west gate of the town. Feeling the importance of avoiding notice in the neighbourhood of the house I sought, I strolled into the open space in front of the Cathedral, and accosting two men who stood talking there, learned that the Ruelle d'Arcy was the third lane on the right of the Rue de Valois, and some little distance along it. Armed with this information I left them, and with my head bent down, and my cloak drawn about the lower part of my face, as if I felt the east wind, I proceeded down the street until I reached the opening of the lane. Without looking up I turned briskly into it.

When I had gone ten paces past the turning, however, I stopped and, gazing about me, began to take in my surroundings as fast as I could. The lane, which seemed little frequented, was eight or nine feet wide, unpaved, and full of ruts. The high blank wall of a garden rose on one side of it, on the other the still higher wall of a house; and both were completely devoid of windows, a feature which I recognised with the utmost dismay. For it completely upset all my calculations. In vain I measured with my eye the ten paces I had come; in vain I looked up, looked this way and that. I was nonplussed. No window opened on the lane at that point, nor, indeed, throughout its length. For it was bounded to the end, as far as I could see, by dead-walls as of gardens.

Recognising, with a sinking heart, what this meant, I saw in a moment that all the hopes I had raised on Simon Fleix's discovery were baseless. Mademoiselle had dropped the velvet bow, no doubt, but not from a window. It was still a clue, but one so slight and vague as to be virtually useless, proving only that she was in trouble and in need of help; perhaps that she had passed through this lane on her way from one place of confinement to another.

Thoroughly baffled and dispirited, I leant for awhile against the wall, brooding over the ill-luck which seemed to attend me in this, as in so many previous adventures. Nor was the low voice of conscience, suggesting that such failures arose from mismanagement rather than from ill-luck, slow to make itself heard. I reflected that if I had not allowed myself to be robbed of the gold token, mademoiselle would have trusted me; that if I had not brought her to so poor an abode as my mother's, she would not have been cajoled into following a stranger; finally, that if I had remained with her, and sent Simon to attend to the horses in my place, no stranger would have gained access to her.

But it has never been my way to accept defeat at the first offer, and though I felt these self-reproaches to be well deserved, a moment's reflection persuaded me that in the singular and especial providence which had brought the velvet knot safe to my hands I ought to find encouragement. Had Madame de Bruhl not picked it up it would have continued to lie in this by-path, through which neither I nor Simon Fleix would have been likely to pass. Again, had madame not dropped it in her turn, we should have sought in vain for any, even the slightest, clue to Mademoiselle de la Vire's fate or position.

Cheered afresh by this thought, I determined to walk to the end of the lane; and forthwith did so, looking sharply about me as I went, but meeting no one. The bare upper branches of a tree rose here and there above the walls, which were pierced at intervals by low, strong doors. These doors I carefully examined, but without making any discovery; all were securely fastened, and many seemed to have been rarely opened. Emerging at last and without result on the inner side of the city ramparts, I turned, and moodily retraced my steps through the lane, proceeding more slowly as I drew near to the Rue de Valois. This time, being a little farther from the street, I made a discovery.

The corner house, which had its front on the Rue Valois, presented, as I have said, a dead, windowless wall to the lane; but from my present standpoint I could see the upper part of the back of this house--that part of the back, I mean, which rose above the lower garden-wall that abutted on it--and in this there were several windows. The whole of two and a part of a third were within the range of my eyes; and suddenly in one of these I discovered something which made my heart beat high with hope and expectation. The window in question was heavily grated; that which I saw was tied to one of the bars. It was a small knot of some white stuff--linen apparently--and it seemed a trifle to the eye; but it was looped, as far as I could see from a distance, after the same fashion as the scrap of velvet I had in my pouch.

The conclusion was obvious, at the same time that it inspired me with the liveliest admiration of mademoiselle's wit and resources. She was confined in that room; the odds were that she was behind those bars. A bow dropped thence would fall, the wind being favourable, into the lane, not ten, but twenty paces from the street. I ought to have been prepared for a slight inaccuracy in a woman's estimate of distance.

It may be imagined with what eagerness I now scanned the house, with what minuteness I sought for a weak place. The longer I looked, however, the less comfort I derived from my inspection. I saw before me a gloomy stronghold of brick, four-square, and built in the old Italian manner, with battlements at the top, and a small machicolation, little more than a string-course, above each story; this serving at once to lessen the monotony of the dead-walls, and to add to the frowning weight of the upper part. The windows were few and small, and the house looked damp and mouldy; lichens clotted the bricks, and moss filled the string-courses. A low door opening from the lane into the garden naturally attracted my attention; but it proved to be of abnormal strength, and bolted both at the top and bottom.

Assured that nothing could be done on that side, and being unwilling to remain longer in the neighbourhood, lest I should attract attention, I returned to the street, and twice walked past the front of the house, seeing all I could with as little appearance of seeing anything as I could compass. The front retreated, somewhat from the line of the street, and was flanked on the farther side by stables. Only one chimney smoked, and that sparely. Three steps led up to imposing double doors, which stood half open, and afforded a glimpse of a spacious hall and a state staircase. Two men, apparently servants, lounged on the steps, eating chestnuts, and jesting with one another; and above the door were three shields blazoned in colours. I saw with satisfaction, as I passed the second time, that the middle coat was that of Turenne impaling one which I could not read--which thoroughly satisfied me that the bow of velvet had not lied; so that, without more ado, I turned homewards, formulating my plans as I went.
