"Well, my friend, tell me how you have enjoyed your evening, and what you think of the company," said Colston, by way of opening the conversation.

"Until supper I had a very pleasant time of it. I enjoyed the business part of the proceedings intensely, as any other mechanical enthusiast would have done, I suppose. But I frankly confess that after that my mind is in a state of complete chaos, in the midst of which only one figure stands out at all distinctly."

"And that figure is?"

"Natasha. Tell me—who is she?"

"I know no more as to her true identity than you do, or else I would answer you with pleasure."

"What! Do you mean to say"—

"I mean to say just what I have said. Not only do I not know who she is, but I do not believe that more than two or three members of the Circle, at the outside, know any more than I do. Those are, probably, Nicholas Roburoff, the President of the Executive, and his wife, and Radna Michaelis."

"Then, if Radna knows, how comes it that you do not know? You must forgive me if I am presuming on a too short acquaintance; but it certainly struck me to-night that you had very few secrets from each other."

"There is no presumption about it, my dear fellow," replied Colston, with a laugh. "It is no secret that Radna and I are lovers, and that she will be my wife when I have earned her."

"Now you have raised my curiosity again," interrupted Arnold, in an inquiring tone.
