'Confound you!' he stuttered, 'stand back! It is not that, I tell you! Mademoiselle is safe and sound, and madame, if she had her senses, would be sound too. It is not our fault if she is not. But I have not got the key of the rooms. It is in Bruhl's pocket, I tell you!'

'Oh!' I made answer drily. 'And Bruhl?'

'Hush, man,' Fresnoy replied, wiping the perspiration from his brow, and bringing his pallid, ugly face, near to mine, 'he has got the plague!'

I stared at him for a moment in silence; which he was the first to break. 'Hush!' he muttered again, laying a trembling hand on my arm, 'if the men knew it--and not seeing him they are beginning to suspect it--they would rise on us. The devil himself could not keep them here. Between him and them I am on a razor's edge. Madame is with him, and the door is locked. Mademoiselle is in a room; upstairs, and the door is locked. And he has the keys. What can I do? What can I do, man?' he cried, his voice hoarse with terror and dismay.

'Get the keys,' I said instinctively.

'What? From him?' he muttered, with an irrepressible shudder, which shook his bloated cheeks. 'God forbid I should, see him! It takes stout men infallibly. I should be dead by night! By God, I should!' he continued, whining. Now you are not stout, M. de Marsac. If you will come with me I will draw off the men from that part; and you may go in and get the key from him.'

His terror, which surpassed all feigning, and satisfied me without doubt that he was in earnest, was so intense that it could not fail to infect me. I felt my face, as I looked into his, grow to the same hue. I trembled as he did and grew sick. For if there is a word which blanches the soldier's cheek and tries his heart more than another, it is the name of the disease which travels in the hot noonday, and, tainting the strongest as he rides in his pride, leaves him in a few hours a poor mass of corruption. The stoutest and the most reckless fear it; nor could I, more than another, boast myself indifferent to it, or think of its presence without shrinking. But the respect in which a man of birth holds himself saves him from the unreasoning fear which masters the vulgar; and in a moment I recovered myself, and made up my mind what it behoved me to do.

'Wait awhile,' I said sternly, 'and I will come with you.'

He waited accordingly, though with manifest impatience, while I sent for M. d'Agen, and communicated to him what I was about to do. I did not think it necessary to enter into details, or to mention Bruhl's state, for some of the men were well in hearing. I observed that the young gentleman received my directions with a gloomy and dissatisfied air. But I had become by this time so used to his moods, and found myself so much mistaken in his character, that I scarcely gave the matter a second thought. I crossed the court with Fresnoy, and in a moment had mounted the outside staircase and passed through the heavy doorway.

The moment I entered, I was forced to do Fresnoy the justice of admitting that he had not come to me before he was obliged. The three men who were on guard inside tossed down their weapons at sight of me, while a fourth, who was posted at a neighbouring window, hailed me with a cry of relief. From the moment I crossed the threshold the defence was practically at an end. I might, had I chosen or found it consistent with honour, have called in my following and secured the entrance. Without pausing, however, I passed on to the foot of a gloomy stone staircase winding up between walls of rough masonry; and here Fresnoy stood on one side and stopped. He pointed upwards with a pale face and muttered, 'The door on the left.'
