"What did he do then?"
"Nothing. I could not explain the incident, and I thought it all over, when something stranger still happened. We had visited the Queen's cell, and Robespierre's cell, and the chapel of the Girondins, and that little door through which the prisoners of September went to get massacred in the court; and we had come back into Paris Street. On the left-hand side of it there's a little staircase which no one ever goes down, because it leads to the cellars; and the only thing to see in the cellars is the eternal night which reigns there. The door at the bottom of this is made of iron bars, a grating—perhaps a thousand years old, or even more. The gentleman they called Adolphe was walking with the lady towards the door of the Guard-room, when without a word the gentleman with the green umbrella ran down the little staircase and called up from the bottom of it in that strange voice I was telling you about:
"'Hi! Where are you going to? It's this way!'
"The other gentleman, the lady, and myself stopped dead as if we had been turned to stone. I must tell you, sir, that his voice was perfectly awful; and there was nothing in his appearance to make one expect such a voice. I ran, in spite of myself as it were, to the top of the staircase. The man with the green umbrella gave me a withering glance. Truly I was thunderstruck, turned to stone and thunderstruck; and when he shouted to me, 'Open this grating!' I don't know how I found the strength to rush down the stairs and open it. Then, when the grating was opened, he plunged into the night of the cellars. Where did he go? How did he find his way? That basement of the Conciergerie is plunged in a terrible darkness which nothing has broken for ages and ages."
"Didn't you try to stop him?" I said sharply.
"He had gone too far; and I hadn't the strength to stop him. The man with the green umbrella just gave me orders; and I had to obey him. And we stood there for a quarter of an hour, half out of our wits: it was so odd. And his wife talked, and his friend talked, and I talked; and we said nothing of any use; and we stared into the darkness till our eyes ached. Suddenly we heard his voice—not his first voice, but his second voice, the awful voice—and I was so overcome, I had to hang on to the bars of the door.
"'Is that you, Simon the Auvergnat?' he cried.
"I didn't answer anything; and as he went past me, I fancied he put a scrap of paper into his breast pocket. He sprang up the staircase three steps at a time; and we went up after him. He did not offer any explanation; and I simply ran to open the door of the prison for them. I wanted to see their backs. When the wicket was opened and the man with the green umbrella was crossing the threshold, he said, for no reason that I could see:
"'We must avoid the wheel.'
"There was no carriage passing."
