"I begin to see," I said.

"Not quite," said my companion, with a laugh. "For the next act was that von Krugen and I quarrelled, and we pretended to wrangle and jangle until I seemed to gain my end, and the little fool thought he owed his life to me. He clung to me and shrank from the 'executioner,' and was altogether in a fit state to promise anything I told him in order to save his skin. I told him it would cost von Krugen his life if it were known that he had not done the work, and that if any one had even a suspicion of who the duke was and who we were all our lives would be sacrificed in a twinkling. By that time he was about wet through with fear, so we told him he must consent to be thought a mad patient of ours whom we, as doctor and attendant, were conveying to an asylum. In this way we took him to Gramberg—not to the castle, but to some place where von Krugen said he would be safe for a time. There he is awaiting your instructions. He's safe enough for a few days, but what after?"

"You have done well and cleverly," I said warmly. "A little fright won't hurt him, and meanwhile matters here have taken a turn which may render it necessary for us to set him free in a few hours," and I told Praga what had happened—except as to the discovery of my imposture—and the tale made a considerable impression on him.

"When that wily old Iscariot says one thing, I always look for another meaning. But you had a master card to play. He must have been mad. And what will you do?"

"If I do not hear from him at once, I shall go on to Landsberg on the chance of my cousin's letter being right, and I will send a messenger to the baron at once."

I was in the act of ringing for a servant when one entered to tell me that Baron Heckscher was waiting to see me.

"He had better not see me," said the Corsican.

"There is no need. I will go to him. Meanwhile get ready to go with me, and communicate with von Krugen to keep the duke where he is until he hears from me."

Then I hurried to the room where Baron Heckscher was waiting.

"I deemed it best to come to you myself," he said on my entrance. "I have been delayed, because I wished to be able to assure you that others are with us in what we propose. Further, there is very important news."
