"It seemed to me they'd be safer here than anywhere else," Charlie observed naïvely. "Nobody ever comes down here, unknown to us. I had it sized up that the fellow who worked those brands would never dream we'd bring the stock right into the Cove. Why, Miss Louise, even I would know better than to put our brand on top of Seabeck's and expect it to pass inspection. If I wanted to steal cattle, I wouldn't go at it that way!"

Billy Louise glanced uncertainly at him and then at Marthy, facing her grimly. She did not know what to think, and she showed it.

"How do you mean—the real rustlers?" She began hesitatingly; and hesitation was not by any means a mental habit with Billy Louise.

"I mean just what I said." Charlie's manner was becoming more natural, more confident. "I've been riding through the hills a good deal, and I've seen a few things. And I've an idea the fellow got a little uneasy." He saw her wince a little at the word "fellow," and he went on, with an impulsive burst of confidence. "Miss Louise, have you ever, in your riding around up above Jones Canyon, in all those deep little gulches, have you ever seen anything of a—corral, up there?"

Billy Louise held herself rigidly from starting at this. She bit her lips so that it hurt. "Whereabouts is it?" she asked, without looking at him. And then: "I thought you would go to any length before you would accuse anybody."

"I would. But when, they deliberately try to hand me the blame—and I'm not accusing anybody—anybody in particular, am I? The corral is at the head of a steep little canyon or gulch, back in the hills where all these bigger canyons head. Some time when you're riding up that way, you keep an eye out for it. That," he added grimly, "is where Peter and I ran across these cattle; right near that corral."

The heart of Billy Louise went heavy in her chest. Was it possible? Doubts are harder to kill than cats or snakes. You think they're done for, and here they come again, crowding close so that one can see nothing else.

"Have you any idea at all, who—it is?" She forced the words out of her dry throat. She lifted her head defiantly and looked at him full, trying to read the truth from his eyes and his mouth.

Charlie Fox met her look, and in his eyes she read pity—yes, pity for her. "If I have," he said, with an air of gently deliberate evasion, "I'll wait till I am dead sure before I name the man. I'm not at all sure I'd do it even then, Miss Louise; not unless I was forced to do it in self-defense. That's one reason why I brought the cattle down here. I didn't want to be placed in a position where I should be compelled to fight back."

Billy Louise ran her gloved fingers down the barrel of her gun, and stuck the weapon back in its holster. "I killed Surbus, Marthy," she said dully. "I had to. He came at me."
