Natasha's brougham was so far an improvement on those of the present day that it had two equally comfortable seats, and on these the four were cosily seated a few minutes after the party broke up. To Arnold, and, doubtless, to Colston also, the miles flew past at an unheard-of speed; but for all that, long before the carriage stopped at the house in Cheyne Walk, he had come to the conviction that, for good or evil, he was now bound to the Brotherhood by far stronger ties than any social or political opinions could have formed. After they had said good-night at the door, and received an invitation to lunch for the next day to talk over the journey to Russia, he and Colston decided to walk to the Savoy, for it was a clear moonlit night, and each had a good deal to say to the other, which could be better and more safely said in the open air than in a cab. So they lit their cigars, buttoned up their coats, and started off eastward along the Embankment to Vauxhall. "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. "And will very soon satisfy it. You saw that horrible picture in the Council-chamber? Yes. Well, I will tell you the whole story of that some day when we have more time; but for the present it will be enough for me to tell you that I have sworn not to ask Radna to come with me to the altar while a single person who was concerned in that nameless crime remains alive.
