"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----" "Audubon? When was this?" queried Norton, frowning. "Four days since--directly he returned after leaving you with him"--and she nodded toward Red Hugh, flushing slightly as she did so. "Mr. Audubon related all that had happened to you and him, but as he was going away with Mr. Ayres they were not sure whom to send here until they thought of me. You see, I would not be suspected or watched, and there was a skiff all ready to----" "But--then you must know----" Norton broke off suddenly, staring into her level grey eyes, wondering if she had been told who Blacknose really was. She looked steadily at him, read his thought, and her face went pale. "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?" "Yes," she almost whispered. "I--I--oh, I do not know what to think or say! But never mind that now, Mr. Norton; Mr. Ayres said that you were to return to Louisville at once----" "You just said he and Audubon were going away?" broke in the puzzled Norton. "They'll be back when you get there. Mr. Ayres has a plan about some boat, and has gone up-river to get some men he can trust. The riverman who was murdered had two brothers----" "Hold on," laughed Norton. "How can I go back when everyone thinks I committed that murder? Straighten me out little by little, Kitty!" "Nobody thinks you did it. Mr. Ayres found that the knife with which the man was murdered belonged to someone else, and also established the fact that you had been outside the tavern all the while. So that is all right. The owner of the knife escaped in a canoe." "And I'll wager his name was Tobin," exclaimed Norton quickly. She looked at him, surprised. "What--how did you know that?" "Because I met Mr. Tobin myself." Norton smiled grimly and glanced at his powder-horn. "Well, that's a relief, Kitty! Now, how about getting back?"
