The certainty, which this sound gave me, that I was in the right house, and that it held also the villain to whom I owed all my misfortunes--for who but Fresnoy could have furnished the broken coin which had deceived mademoiselle?--had a singularly inspiriting effect upon me. I felt every muscle in my body grow on the instant; hard as steel, my eyes more keen, my ears sharper--all my senses more apt and vigorous. I stole off like a cat from the balustrade, over which I had been looking, and without a second’s delay began the search for mademoiselle’s room; reflecting that though the garrison now amounted to four, I had no need to despair. If I could release the prisoners without noise--which would be easy were the key in the lock--we might hope to pass through the hall by a tour de force of one kind or another. And a church-clock at this moment striking Five, and reminding me that we had only half an hour in which to do all and reach the horses, I was the more inclined to risk something. The light which I had seen from below hung in a flat-bottomed lantern just beyond the head of the stairs, and outside the entrance to one of two passages which appeared to lead to the back part of the house. Suspecting that M. de Bruhl’s business had lain with mademoiselle, I guessed that the light had been placed for his convenience. With this clue and the position of the window to guide me, I fixed on a door on the right of this passage, and scarcely four paces from the head of the stairs. Before I made any sign, however, I knelt down and ascertained that there was a light in the room, and also that the key was not in the lock. So far satisfied, I scratched on the door with my finger-nails, at first softly, then with greater force, and presently I heard someone in the room rise. I felt sure that the person whoever it was had taken the alarm and was listening, and putting my lips to the keyhole I whispered mademoiselle’s name. A footstep crossed the room sharply, and I heard muttering just within the door. I thought I detected two voices. But I was impatient, and, getting no answer, whispered in the same manner as before, ‘Mademoiselle de la Vire, are you there?’ Still no answer. The muttering, too, had stopped, and all was still--in the room, and in the silent house. I tried again. ‘It is I, Gaston de Marsac,’ I said. ‘Do you hear? I am come to release you.’ I spoke as loudly as I dared, but most of the sound seemed to come back on me and wander in suspicious murmurings down the staircase. This time, however, an exclamation of surprise rewarded me, and a voice, which I recognised at once as mademoiselle’s, answered softly: ‘What is it? Who is there?’ ‘Gaston de Marsac,’ I answered. ‘Do you need my help?’
