"Who's there?"

"I! The Doctor!"

"Ah! that is another matter! I'll see whether you are telling the truth."

He went back into his lodge to get a lantern, crossed the outer court with the snow up to his middle, and staring at me through the grating:

"I beg your pardon, monsieur the doctor," he said; "I thought you were asleep up-stairs in Hugh's Tower. It was you ringing! Now I see why Sperver came to me at midnight to ask if any one had gone out. I said no, for I never saw you go out."

"But for Heaven's sake, Knapwurst, open the door! You can tell me all this later."

"Be patient for a moment, monsieur."

And the dwarf deliberately turned the lock and drew back the bolts, while I stood with my teeth chattering, and shivering from head to foot.

"You are cold, Doctor," observed the diminutive porter, "and you cannot get into the Castle. Sperver has fastened the inside door, I don't know why; he doesn't ordinarily; the grating is enough. Come into the lodge and warm yourself. You won't find my room much to boast of; properly speaking, it is nothing but a sty, but when you are cold you don't spend much time in looking about."

Without replying to his chatter I followed him as rapidly as possible, burning with impatience to learn what things were passing in the Castle, but seeing nothing for it but to wait till dawn.
