Abruptly, he turned his back upon them and stood leaning on his rifle, his shoulders shaking. Norton realized swiftly that the old man had found some resemblance in her to that wife whom he had lost in such tragic fashion, and in quick pity he gave the girl a warning look and hastened to change the current of Red Hugh's thoughts.

"But, Kitty—how on earth came Ayres to send you, of all people?" he cried in half-anger, half-wonder. "He knew there was danger in it——"

"Listen, please," she broke in, her hand on his arm and her eyes searching his face hungrily. "After you left me, that day, I saw Colonel Boone and told him what you had said. He knew nothing about the pin, but he said to trust you and—and I do. Then father went off on a month's hunt, so I was going to visit with Mistress Zach Taylor had not Mr. Ayres and Mr. Audubon come to see me——"

"Yes," she nodded quietly. "Mr. Audubon told me all about it. I do not quite believe it can be possible, despite what you and Mr. Audubon heard. You see, sir, Mr. Duval has exerted some influence over my fa——"

"Over Abel Grigg, you mean," interrupted Norton gravely. He was all the more astonished that she had come on this mission, knowing what she did.

"Over—him," she went on, avoiding the issue. "But he's not bad at heart, really! And I came here partly to ask you to help him—I mean, if you find there is a gang of pirates, don't be too harsh with him until he is proven guilty——"

"I promise you that, sweet Kitty," smiled Norton. Then of a sudden the warmth died out of his brown eyes, and his face went hard. "Perhaps you were not told how he agreed to sell you to Duval, eh?"
