I moved to the door and locked it noiselessly. I dared not open it to see if the servant had gone, for if he had not that would have roused his suspicions at once. The Duke had already crossed to the further side of the room, and I joined him there.

He wasted no time in preliminaries.

“Mishka has told me all,” he began, speaking in English, though still in the hoarse low growl appropriate to his assumed character. “And I have learned much since. There is to be a meeting to-night, and if things are as I suspect she will be brought before the tribunal. We must save her if we can. Will you come? To say it will be at the risk of your life is to put it mildly. It will be a forlorn hope.”

“I’ll come; tell me how,” I said.

“You will go to the place where you met Mishka to-day, dine there, and change your clothes. They will have some for you, and you need not use the formula. They expect you already; I knew you would come! Mishka will join you, and will accompany you to the rank where I shall be waiting with my droshky. You will hire me in the usual way; and we will tell you my plans when we are clear of the city. Have you any weapon?”

“No.”

He felt in an inner pocket of his filthy greatcoat and brought out a revolver and a handful of spare cartridges.

“It’s loaded; you can have these, too, though if there’s any shooting I doubt if you’ll have the chance of reloading. Let’s hope you won’t fall in with the police for the third time to-day! Mishka will join you between nine and ten. We need not start till then,—these light nights are a drawback, but that cannot be helped. The meeting will be held as usual, after midnight. That is all now. I must not stay longer. Give me the note you spoke of. A blank sheet—anything—I will destroy it immediately.”

I put a sheet of note-paper into an envelope, and addressed it to Lieutenant Mirakoff at his barracks. His was the first name that occurred to me.
