"Well, so for the moment you have succeeded," he said quietly.

I turned and stared at him; I did not understand in the least what he meant. "In what have I succeeded?" I asked. "Don't I tell you that I'm not responsible for the business we've just been talking about."

"You know what I'm referring to," he said, harshly. "I'm speaking of the girl."

I had learnt wisdom, and I controlled myself with an effort. "What of her?" I asked carelessly.

I saw his eyes flash, and noticed that his teeth were clenched hard as he strode along beside me. "You've got her!" he burst out at last, "but you shan't keep her. You've been wise enough, too, to hide her away somewhere where you don't go yourself. I've had you watched, and I know that. But I'll find her, and if I don't find her within a certain time, determined on by myself, I'll tell my story, and you shall hang!"

I was on the point of blurting out that I knew nothing about the matter, but on second thoughts I held my tongue. I guessed in a moment that Debora must have made her escape from the house, and must be somewhere in hiding, and, of course, she would not know where to communicate with me. My heart leapt at the thought that she was free; it sank again at the thought that she might be penniless and unprotected amongst strangers. At the same time I decided that I would not give him any undue advantage over me, by letting him understand that I did not know where the girl was. I merely shrugged my shoulders and laughed.

"You can take my warning, and make the most of it," he said abruptly. "If Debora does not return to me within the time I have mapped out—and I shall not even tell you what that time is—I tell what I know to the right people."

I remembered what Debora had said to me about her certainty that this man had caused the death of Gregory Pennington; I had a shot at that matter now. "And some explanation will be needed regarding the man you allowed to be shut away in a grave in Penthouse Prison," I said quietly.

He turned his head sharply, and looked at me. I regarded him steadily. "That's a matter you'll have to explain," he said, with a grin.

"I?" It was my turn to look amazed.
