"It is certainly an extraordinary thing," Gurdon muttered. "I don't think I ever listened to a weirder tale. And did the Dutch woman confess to her crime? This strikes me as being a fitting end to the story. I suppose it came from her lips."
"She didn't confess, for the simple reason that she had no mind to confess with," Venner explained. "Of course, certain neighbors knew something of what was going on, but they never knew the whole truth, because, after the appearance of the last finger, Mrs. Van Fort went stark raving mad. She lived for a few days, and at the end of that time her body was found in a waterfall close to her house. That is the story of the Four Finger Mine so far as it goes, though I should not be surprised if we manage to get to the last chapter yet. Now, you are an observant man—did you notice anything peculiar in Fenwick's appearance to-night?"
Gurdon shook his head slowly. It was quite evident that he had not noticed anything out of the common in the appearance of the millionaire. Venner proceeded to explain.
"Let me tell you this," he said. "When I married my wife, we were within an easy ride of the locality where the Four Finger Mine is situated. Mind you, our marriage was a secret one, and I presume that Fenwick is still in ignorance of it, though, of course, he was fully aware of the fact that I had more than a passing admiration for Vera. I merely mention this by way of accentuating the little point that I am going to make. It is more than probable that, when I stumbled upon Fenwick and the girl who passes for his daughter, he also was in search of the Four Finger Mine. When he came in to-night he, of course, recognised me, though I treated him as an absolute stranger whom I had met for the first time. You will see presently why I treated him in this fashion. I am glad I spoke to him, because I noticed a slight thing that throws a flood of light upon the mystery. Now, did it escape your observation, or did you notice that Fenwick took the box I gave him in his right hand?"
"Oh, dear, no," Gurdon said. "A little thing like that would be almost too trivial for the typical detective of the cheap story."
"All the same, it is very important," Venner said. "He took the box in his right hand; he made as if to extend his left, then suddenly changed his mind, and put it in his pocket. But he was too late to disguise from me that he had—"
"I know," Gurdon shouted. "He had lost all the fingers on his left hand. What an amazing thing! We must get to the bottom of this business at all costs."
"That is precisely what we are going to do," Venner said grimly. "I am glad you are so quick in taking up the point. When I noted the loss of those fingers, I was absolutely staggered for a moment. If he had been less agitated than he was, Fenwick would have guessed what I had seen. I need not tell you that when I last saw Fenwick his left hand was as sound as yours or mine. The inference of this is, that Fenwick has fallen under the ban of the same strange vengeance that overtook Van Fort and his wife. There is not the slightest doubt that he discovered the mine, and that he has not yet paid the penalty for his temerity."
"I presume the penalty is coming," Gurdon said. "What a creepy sort of idea it is, that terrible vengeance reaching across a continent in such a sinister fashion. But don't forget that we know something as to the way in which this thing is to be brought about. Don't forget the cripple who sat at yonder table to-night."
"I am not likely to forget him," Venner observed. "All the more because he evidently knows more about this matter than we do ourselves. When he came here to-night, he little dreamed that there was one man in the room, at least, who had a fairly good knowledge of the Four Finger Mystery. We shall have to look him out, and, if necessary, force him to speak. But it is a delicate matter, and as far as I can see, one not unattended with danger."
