"I don't quite see what we are going to do next," Venner said. "So far, we have been exceedingly fortunate to find ourselves in possession of a set of clues which would be exceedingly valuable to the police. But how are we going to use these clues is quite another matter. What do you suggest?" "Keeping a close eye upon Fenwick at any rate. For that purpose it would not be a bad idea to employ a private inquiry agent. He need know nothing of what we are after." Thereupon it was decided that Gurdon was to dine with Venner that night and go fully into the matter. CHAPTER X THE SECOND FINGER It was, perhaps, fortunate for all concerned that, though Venner was so closely identified by the irony of Fate with the movements of Mark Fenwick, he was not known to the latter personally, though they had been almost side by side three years previous in Mexico. Therefore, it was possible for Venner to get a table in the dining-room quite close to that of the alleged millionaire. It was all the more fortunate, as things subsequently turned out, that Fenwick had returned to town that afternoon and had announced his intention of dining at the hotel the same evening. This information Venner gave to Gurdon when the latter turned up about half-past seven. Then the host began to outline the plan of campaign which he had carefully thought out. "Fenwick is dining over there," he said. "He generally sits with his back to the wall, and I have had our table so altered that we can command all his movements. Vera, of course, will dine with him. Naturally enough, she will act as if we were absolute strangers to her. That will be necessary." "Of course," Gurdon admitted. "But isn't it a strange thing that you should be an absolute stranger to Fenwick?" "Well, it does seem strange on the face of it. But it is capable of the easiest explanation. You see, when I first met Vera, she was at school in a town somewhere removed from the Four Finger Mine. I saw a good deal of her there, and when finally she went up country, we were practically engaged. At her urgent request the engagement was kept a secret, and when I followed to the Mines it was distinctly understood that I should not call at Fenwick's house or make myself known to him except in the way of business. As it happens, we never did meet, and whenever I saw Vera it was usually by stealth. The very marriage was a secret one, and you may charge me fairly with showing great weakness in the matter. But there, I have told you the story before, and you must make the best of it. On the whole, I am glad things turned out as they did, for now I can play my cards in the game against Fenwick without his even suspecting that he has me for an opponent. It is certainly an advantage in my favor."
