The marshal lunged for him; but the Silent One, reaching a long arm from the door-step, rapped him smartly on the head with his gun. The marshal squawked and went down in a formless heap. “Come on, boys,” said the Silent One coolly. “I think we'd better go. Your friend seems to have vanished in thin air.” Rowdy, grumbling mightily over what looked unpleasantly like retreat, was pushed toward his horse and mounted under protest. Likewise Pink, who was for staying and cleaning up the whole town. But the Silent One was firm, and there was that in his manner which compelled obedience. Harry Conroy might have been an optical--and aural--illusion, for all the trace there was of him. But when the three rode out into the little street, a bullet pinged close to Rowdy's left ear, and the red bark of a revolver spat viciously from a black shadow beside the Come Again. Rowdy and the two turned and rode back, shooting blindly at the place, but the shadow yawned silently before them and gave no sign. Then the Silent One, observing that the marshal was getting upon a pair of very unsteady legs, again assumed the leadership, and fairly forced Rowdy and Pink into the homeward trail. CHAPTER 7. Rowdy in a Tough Place. Rowdy, with nice calculation, met Miss Conroy just as she had left the school-house, and noted with much satisfaction that she was riding alone. Miss Conroy, if she had been at all observant, must have seen the light of some fixed purpose shining in his eyes; for Rowdy was resolved to make her a partner in his dreams of matters domestic. And, of a truth, his easy assurance was the thinnest of cloaks to hide his inner agitation. “The round-up just got in yesterday afternoon,” he told her, as he swung into the trail beside her. “We're going to start out again to-morrow, so this is about the only chance I'll have to see you for a while.” “I knew the round-up must be in,” said Miss Conroy calmly. “I heard that you were in Camas a night or two ago.” Inwardly, Rowdy dodged. “We camped close to Camas,” he conceded guardedly. “A lot of us fellows rode into town.” “Yes, so Harry told me,” she said. “He came over to see me yesterday. He is going to leave--has already, in fact. He has had a fine position offered him by the Indian agent at Belknap. The agent used to be a friend of father's.” She looked at Rowdy sidelong, and then went straight at what was in the minds of both. “I'm sorry to hear, Mr. Vaughan, that you are on bad terms with Harry. What was the trouble?” She turned her head and smiled at him--but the smile did not bring his lips to answer; it was unpleasantly like the way Harry smiled when he had some deviltry in mind. Rowdy scented trouble and parried. “Men can't always get along agreeably together.” “And you disagree with a man rather emphatically, I should judge. Harry said you knocked him down.” Politeness ruled her voice, but cheeks and eyes were aflame.
