"I think," said Swan quietly, "we will go now and find out where that horse went last night."
"A good idea," Lone agreed. "Do you see how it was done, Swan? When he saw the team coming, away back toward Echo, he rode down into that wash and tied his horse. He was walking when Frank overtook him, I reckon—maybe claiming his horse had broke away from him. He had a rock in his handkerchief. Frank stopped and gave him a lift, and he used the rock first chance he got. Then I reckon he stuck the whisky bottle in Frank's pocket and heaved him out. He dropped the handkerchief out of his hip pocket when he jumped out of the rig. It's right simple, and if folks didn't get to wondering about it, it'd be safe as any killing can be. As safe," he added meaningly, "as dragging Fred Thurman, or unhooking Brit's chain-lock before he started down the canyon with his load of posts."
Swan did not answer, but turned back to where the horse had been left tied and took up the trail from there. As before, the dog trotted along, Lone riding close behind him and Swan striding after. They did not really need the dog, for the hoofprints were easily followed for the greater part of the way.
They had gone perhaps four miles when Lone turned, resting a hand on the cantle of his saddle while he looked back at Swan. "You see where he was headed for, don't yuh, Swan?" he asked, his tone as friendly as though he was not under arrest as a murderer. "If he didn't go to Whisper, I'll eat my hat."
"You're the man to know," Swan retorted grimly. And then, because Lone's horse had slowed in a long climb over a ridge, he came up even with a stirrup. "Lone, I hate to do it. I'd like you, if you don't kill for a living. But for that I could shoot you quick as a coyote. You're smart—but not smart enough. You gave yourself away when I showed you Fred's saddle. After that I knew who was the Sawtooth killer that I came here to find."
"You thought you knew," Lone corrected calmly.
"You don't have to lie," Swan informed him bluntly. "You don't have to tell anything. I find out for myself if I make mistake."
"Go to it," Lone advised him coldly. "It don't make a darn bit of difference to me whether I ride in front of you or behind. I'm so glad you're here on the job, Swan, that I'm plumb willing to be tied hand and foot if it'll help you any."
"When a man's too damn willing to be my prisoner," Swan observed seriously, "he gets tied, all right. Put out your hands, Lone. You look good to me with bracelets on, when you talk so willing to go to jail for murder."
He had slipped the rifle butt to the ground, and before Lone quite realized what he was doing Swan had a short, wicked-looking automatic pistol in one hand and a pair of handcuffs in the other. Lone flushed, but there was nothing to do but hold out his hands.
