When he came to himself again he was lying in an armchair, to which he was fastened by a maze of cords, wound cunningly about him. As his head became clear and less confused, he realised that he was in a kind of library, the walls of which were lined with books. Opposite him Silva was seated, with a placid smile upon his face.

"I think we have met before," he said.

"I have had that advantage," Walter said grimly. "And now you will, perhaps, be good enough to explain what you mean----"

"No," Silva hissed. A sudden anger flamed out of his eyes. "On the other hand, the explanation comes from you. For the time being, at any rate, this house is mine. I have paid for it, and I propose to spend my time quietly here for the next month or two. I am hardly settled down here before you come along in this unceremonious fashion and burgle the place. Why?"

"That you know quite as well as I do," Walter retorted. "Really, you are a man of amazing audacity. Now don't you know that the law punishes people severely for this kind of thing?"

"And what kind of thing do you allude to?"

"Why should you assume ignorance in that way? You know perfectly well what I mean. To my certain knowledge you have made three attempts on the life of Lord Ravenspur, and even that does not seem to be sufficient. Last night you managed to lure Miss Vera Rayne away from London, and she is in this house at the present moment. That she is detained here against her will I feel certain."

"Oh, indeed," Silva sneered. "Would you like to search the house? If I give you permission to go over the premises, will you be prepared to apologise and go away without further delay?"

A cold chill crept up Walter's spine. The man spoke with such an air of confidence and triumph that Walter began to feel that the mission had failed. Beyond all question, Silva had discovered the plot, and already he had managed to get Vera out of the way. The Italian could not be acting. His air was too assured for that.

"We need not say anything about apologies," Walter said; "but if you can prove to me that Miss Rayne is not in the house, why, then, for the present, at any rate, I will not trouble you."
