“I will swear to the innocence of the Duchess, also to that of the Duke. They are simply tools. They have been made use of by a superior intelligence, by a man who has a strong hold over the Duke.”

“I wish, Mr Moreno, you were able to take us a little more into your confidence. Would it not be possible to bag the whole lot to-night?”

The Chief of the Police rubbed his hands at the thought. “Ah, that would be a fine idea. And I suppose, Mr Moreno, you have it in your power to enable us to do so?”

“Gently, gentlemen, if you please. Don’t be ungrateful. I am helping you somewhat to-night. And because I am doing this, you want to rush things,” answered the young journalist in his usual quiet way. “Now, look you, much as I desire to serve you, I have a very tender regard for my own skin.”

“Naturally,” cried the Secret Service man. And the Chief of Police echoed him.

“The secret of this project to-night has been entrusted to a good many people,” continued Moreno. “If it fails, as you promise me it will fail, two things will occur to the mind of the Chief—one that the brotherhood has been betrayed by one in their counsels, the other that your spies noticed something suspicious in the behaviour of the woman, and that she was arrested on the strength of that suspicious behaviour.”

The two men nodded their heads. They began to see the drift of his observations.

“I was at first designed to take part in this project, but the original programme was altered. Had it been adhered to, I think I could have enabled you to bag the whole lot, at any rate, most of them, and yet escaped scot free myself, of course with your co-operation.”

“We dare not ask you to disclose your plan?” insinuated the Secret Service man gently.

Moreno shook his head. “I think not. But if this coup fails, there will be another planned shortly. By that time my ideas will be perfected, and I trust I shall be able to do what you want, and escape with a whole skin. Only one member of the brotherhood will be here to-night. The others are scattered about. Suspicion would at once fall upon me if every one except myself were taken.”
