The door opened, and to my amazement Wetter stood there. He was panting, as though he had run fast, and his air displayed agitation. The Countess ran to him instantly. His coming seemed to revive the fears which her love had laid to rest.

"What is it?" she cried. "What's the matter?"

Wetter took absolutely no notice of her. Walking on as though she were not there, he came straight up to me. He spoke in tones of intense emotion, and with the bluntness that excitement brings.

"You must come with me at once," he said in an imperious way. "They've sent for you to my house; we can get in together by the back door."

"But what's the matter, man?" I cried, divided between puzzle and anger.

"You're wanted; you must go to Hammerfeldt's."

"To Hammerfeldt's?"

"Yes. He's dying. Come along."

"Dying! My God!"

"The message is urgent. There's no time to lose. If you want to see him alive, come. I said you were lying down in my study. If you don't come quickly, it will be known where you are."
