"And now," he said, "I am going to tell you my part of this strange story, and you will see, Mrs. Winslow, that the two parts—yours and mine—fit, and that the vengeance for which I see you crave, is in your hands. I shall further show you how to arrange so that you need not appear in the matter if Sir Angus Kinross prove kind, as I feel sure he will be—to you."

Katty clasped her hands together tightly. She felt terribly moved and excited. Vengeance? What did this wonderful old man mean?

"Dealers in money," began Mr. Greville Howard thoughtfully, "have to run their own international police, and that, my dear young lady, is especially true of the kind of business which built up what I think I may truly call my fame, as well as my fortune. During something like forty years I paid a large subsidy each year to the most noted firm of private detectives in the world—a firm, I must tell you, who have their headquarters in Paris. Though I no longer pay them this subsidy, for mine was a one-man business, I still sometimes have reason to employ them. They throw out their tentacles all over the world, and their chief, a most intelligent, cultivated man, is by way of being quite a good friend of mine. I always thoroughly enjoy a chat with him when I am going through Paris on my way to my villa in the South of France. It is to this man that the credit of what I am about to tell you, the credit, that is, of certain curious discoveries connected with the mystery of Mr. Godfrey Pavely's death, is due."

Greville Howard waited a few moments, and then he spoke again.

"I must begin at the beginning by telling you that when this Fernando Apra came to see me, I formed two very distinct opinions. The one, which is now confirmed by what you have told me, was that the man was not a Portuguese; the other was that he was 'made up.' I felt certain that his hair was dyed, and the skin of his face, neck and hands tinted. He was a very clever fellow, and played his part in a capital manner. But I took him for an adventurer, a man of straw, as the French say, and I believed that Mr. Godfrey Pavely was being taken in by him. Yet there were certain things about this Apra that puzzled me—that I couldn't make out. An adventurer very rarely goes to the pains of disguising himself physically, for his object is to appear as natural as possible. There was yet another reason why the adventurer view seemed false. All the time we were talking, all the time he was enthusing—if I may use a very ugly modern word—about the prospects of this gambling concession, I had the increasing conviction that he was not serious, that he was not out for business—that he had come to see me with some other motive than that of wishing me to take an interest in his scheme."

Greville Howard leant forward, and gazed earnestly into his visitor's face. "I felt this so strongly that the thought did actually flash across me more than once—'Is this man engaged in establishing an alibi?' When I asked him for the name and address of the French references to which Mr. Pavely had made an allusion in his letter of introduction, I saw that he was rather reluctant to give me the names. Still he did do so at last, the bankers being——"

"Messrs. Zosean & Co.," exclaimed Katty. "I have sometimes thought of going to see them."

"You would have had your journey for nothing. As I shall soon show you, they were—they still are—an unconscious link in the chain. To return to Apra, as we must still call him. So little was I impressed by this peculiar person that I expected to hear nothing more of him or of his gambling concern. But one day I received a letter from Mr. Godfrey Pavely, telling me that he himself wished to see me with reference to the same matter. I saw at once that he really did mean business. He was very much excited about the prospects of the undertaking."

Mr. Greville Howard paused. He looked attentively at his visitor, but Katty's face told him nothing, and he continued: "I cross-examined him rather carefully about this Fernando Apra, and I discovered that he had only seen the fellow twice, each time rather late in the evening, and by artificial light. I then told him of my conviction that Apra was playing a part, but he scouted the idea. Our unfortunate friend was a very obstinate man, Mrs. Winslow."
