Mary stood up. "Yes, we must be going. Are you comfortable in the cave?"
"Yes," Kenneth returned. "It is good enough. We have a big bed of dry leaves and grass, and if Martin would only sleep we'd be all right."
"I try, but I can't," the blue-eyed boy said, in an uncertain, half-abashed tone. "There was a night-owl near us last night, and it was hooting, and, my God! sis, the thing seemed to talk. I never had anything against Tobe Keith in my life. In fact, he and I used to fish and swim together when we'd run away from school, and to think that I actually—Turn around, and I'll show exactly how I clamped his arms and how he was bent down when Ken fired."
"No, not now," Charles protested. "Your sister is very nervous. She almost fainted just now."
"No, don't go into it," Kenneth mumbled, his mouth full. "I haven't anything against Tobe, either. We were both drinking, but they tell me the law doesn't excuse a fellow on that account. I didn't know what I was doing, but I couldn't prove it to a jury. I reckon they would call it deliberate. You see, Tobe and I had had words the day before over another matter, and I remember I made some threats about what I'd do to him. Oh, if he dies they will have a case against us. I know that well enough, and we must stay under cover till we can get West."
"I thought Tobe had a knife," Martin said, piteously. "I was sure I saw him draw it, and I held him to keep him from stabbing Ken. You know Tobe did rip a fellow open once in a fight. They say I was mistaken and that it was just a spoon he had been eating oysters with, and that he dropped it as soon as I grabbed him. Sis, will you let us know how he is as often as you can?"
"Yes, yes," the girl promised, "and if you don't hear it will be a sign of good news. Remember that, and, brother, do try to sleep to-night. You look sick."
She glanced at the sky again. She kissed them both and walked away. They had gone only a few paces when Charles suddenly turned back and joined them.
"Your sister may not be able to come every time," he said. "But I know the way now, for I took note of the landmarks, and I'll come by myself."
"That will be bully of you," Kenneth said. "By the way, we must have a signal, so that I'll know who it is. Suppose you whistle twice slowly and three times fast, and I'll answer and come out."
