Ten minutes later, Ross, with a hot and angry face, was back in the lobby. His indignation burned against Leslie, who had, unconsciously, helped to put him in the hole in which he found himself. The subdued laugh which had marked his retreat from the barroom rang long in his ears. The sheriff's laugh was the loudest. "Arrest will serve him right!" muttered Ross as he entered the dining-room. "There isn't a reason on earth why he shouldn't have told me his right name when he told me the rest." Angrily Ross ate his supper, glowering down at his plate and not noticing the entrance of the McKenzies with the sheriff. After supper he went up to his room. The door was unlocked, the key having been long since lost. A single electric bulb swinging over the dresser was alight. Under the bulb lay a sealed and soiled envelope. Ross picked it up and turning it over came on the direction, "Doc Tenderfoot," in a sprawling and carefully careless hand. Wonderingly he opened the envelope. Within was a note written with a lead pencil on the back of a yellow advertising sheet. It ran: "Leslie's name is Quinn, not Jones. His father is A. B. Quinn, North Bend, Okla., or 14 Castle Street, Omaha. He is in Omaha now waiting for Leslie. Sheriff is to send him there. Mum is the word about this note--to him or Leslie or the McKenzies. If I did not know you were on the square you would not get it to be mum about." CHAPTER X A NEWCOMER ON MEADOW CREEK "'OLD man Quinn!'" Ross cried aloud. "'Old man Quinn' and the sheep war. And Leslie is his son!" It all came back, the story he had almost forgotten in the stress of events on Meadow Creek, the conversation on the train, old Sheepy's tale and, at last, his suspicions concerning Lon Weston with his dyed hair. And when his memory brought Lon into mental view, Ross's face lit up with a sudden flash of intelligence. "It was Weston that I saw in the tent, and it was Weston that went into the barroom ahead of me!" He laid the note on the dresser and, bending under the electric light, studied it. There was nothing to show who had written it except the caution at the end. That might have emanated from Waymart, but the language was better than he would have used. Ross felt that it was Lon Weston who had written that message. Of course, if such was the case, and Lon was the fourth whom old man Quinn was looking for, that warning not to give the unsigned writer away would be accounted for. It might, in some way, be the clew that would lead to Lon's detection. Ross now recalled how Lon had lain with one arm over his face all the time that Wilson and Leslie had been at the stage camp. He could not now recall whether or not the injured man's name had been spoken in Leslie's presence. But he did remember that Leslie had said of the McKenzies that perhaps they were men at some time in his father's employ, in which case he might not know them, but that they would probably recognize him.
