Jack went sniffing obediently in wide circles, crossing unconcernedly Lone's footprints while he trotted back and forth. He hesitated once on the trail of the horse he had followed, stopped and looked at Swan inquiringly, and whined. Swan whistled the dog to him with a peculiar, birdlike note and called to Lone.
"You come back, Lone, and let Yack take a damn good smell of you. By golly, if that dog lies to me this time, I lick him good!"
Lone came back, grinning a little. "All right, now maybe you'll listen to reason. I ain't the kind to tell all I know and some besides, Swan. I've been a Sawtooth man, and a fellow kinda hates to throw down his outfit deliberate. But they're going' too strong for any white man to stand for. I quit them when they tried to get Brit Hunter. I don't know so much, Swan, but I'm pretty good at guessing. So if you'll come with me to Whisper, your dog may show yuh who owns that handkerchief. If he don't, then I'm making a mistake, and I'd like to be set right."
"Somebody rode that horse," Swan meditated aloud. "Yack don't make a mistake like that, and I don't think I'm blind. Where's the man that was on the horse? What you think, Lone?"
"Me? I think there was another horse somewhere close to that outcropping, tied to a bush, maybe. I think the man you're after changed horses there, just on a chance that somebody might trail him from the road. You put your dog on the trail of that one particular horse, and he showed yuh where it was feeding with the bunch. It looks to me like it was turned loose, back there, and come on alone. Your man went to Whisper; I'll bank money on that. Anyway, your dog'll know if he's been there."
Swan thought it over, his eyes moving here and there to every hint of movement between the skyline and himself. Suddenly he turned to Lone, his face flushing with honest shame.
"Loney, take a damn Swede and give him something he believes, and you could pull his teeth before you pull that notion from his thick head. You acted funny, that day Fred Thurman was killed, and you gave yourself away at the stable when I showed you that saddle. So I think you're the killer, and I keep on thinking that, and I've been trying to catch you with evidence. I'm a Swede, all right! Square head. Built of wood two inches thick. Loney, you kick me good. You don't have time to ride over here, get some other horse and ride back to the Quirt after Frank was killed. You got there before I did, last night. We know Frank was dead not much more than one hour when we get him to the bunk-house. Yack, he gives you a good alibi."
"I sure am glad we took the time to trail that horse, then," Lone remarked, while Swan was removing the handcuffs. "You're all right, Swan. Nothing like sticking to an idea till you know it's wrong. Now, let's stick to mine for awhile. Let's go on to Whisper. It ain't far."
They returned to the rocky hillside where the trail had been covered, and searched here and there for the tracks of another horse; found the trail and followed it easily enough to Whisper. Swan put Jack once more on the scent of the handkerchief, and if actions meant anything, Jack proved conclusively that he found the Whisper camp reeking with the scent.
But that was all,—since Al was at that moment trailing Lorraine toward the Sawtooth.
