"Excellent!" he murmured. "And if I refuse? To save Polly, you would have to call your bloodhounds off."
"It is too late for that," said Locke sternly. "And even if it were not, it would be better that Polly should suffer even the shame of publicity than that you should remain in any way in touch with her life."
"I see!" murmured Captain Francis Newcombe again. "But with exposure as inevitable as you say it is, it is too bad that Polly should—er—nevertheless suffer her share of this shameful publicity whether I go or not."
"You fence well," said Locke with a grim smile. "Scotland Yard sooner or later will know, but they will not make public what they know until they have laid hands upon their man. It is your freedom that is at stake. I told you I did not think you would venture to return to London."
"Locke," said Captain Francis Newcombe softly, "permit me to return the compliment—but also with reservations. You are clever—but having overlooked one little detail, as so often happens even to the cleverest of us all, your scheme as regards keeping Polly in ignorance of my unworthiness falls to the ground. That envelope you hold in your hand—I was wondering—it simply occurred to me—how Polly was to be informed that—er—her name is—I think you said—Gray."
"I had not overlooked it," Locke answered evenly. "Polly's parentage is a matter that precedes your entry into her life by many years; it is a matter that is logically within the knowledge of this Mrs. Wickes. I shall cable London to-day. There will be means of securing Mrs. Wickes' confession on this point. These papers will come from her."
"Ah, yes!" said Captain Francis Newcombe gently. "Quite so! Perhaps, after all, I am the one who overlooked detail. But if by any chance this Mrs. Wickes could not be found—what then?"
Locke studied the other's face. It was impassive; no, not quite that—there was something that lurked around the corners of the man's mouth—like a hint of mockery.
"In that case," he said steadily, "I should have done my best to save her from the knowledge of what you are, for I should have to tell her; but meanwhile you will have gone from here, and, as I have already said, she will be saved the brutal notoriety that would attach to her wherever she went, and until she died mar her life, if Captain Francis Newcombe's 'case' were blazoned abroad from the criminal courts of England—and that, in the last analysis, is what really matters." He thrust the envelope abruptly back into his pocket, and as abruptly took out his watch and looked at it. "I do not want to detain the boat. You know where to find Paul Cremarre. Get him, and take him with you. Your baggage has been searched—so has Runnells'. I do not for a moment think you found that which specifically brought you to this house. I doubt, indeed, now that Mr. Marlin is dead, if it ever will be found by anybody. But in so far as you are concerned, assurance will be made doubly sure—the three of you will be subjected to a personal search before you are landed on the other side." He snapped his watch back into his pocket. "Shall I find out if Miss Marlin is able to see you?"
Captain Francis Newcombe examined the glowing tip of his cigarette with every appearance of nonchalance—but the brain of the man was seething in a fury of action. He was beaten—in so far as the existence, the entity of a character known as Captain Francis Newcombe was concerned—he was beaten.... This cursed, meddling fool had beaten him.... Damn that shot that he had missed in the darkness.... He could not draw his revolver and fire another and kill this man—not now.... To do that here would be suicide.... And, besides, there was still half a million dollars.... Quite a sop! ... Mrs. Wickes didn't count one way or the other—but Paul Cremarre—that was awkward.... The island must be left in quiet and repose in so far as anything pertaining to the attempted robbery was concerned—an incident that with his departure was closed.... Paul Cremarre must be accounted for.... Well, the truth was probably the safest, since denial would only result in a search for a third man that Locke knew had been here.... That Locke should think that Paul Cremarre had come here as part of the prearranged plan was probably all the better.... It left no lingering doubts....
