"Just my argyment," declared the first speaker, rescuing a flagon of tea from the edge of the fire. "An' them as complains, they dunno what they're talkin' about. They'd have cause ter grumble supposin' that power was abused—if ever the wrong man was arrested or if the guilty one was ever allowed ter escape."

"As to that," rejoined Silk, "we are all liable to make mistakes. I have known a case or two of wrongful arrest, and I won't say that we have invariably succeeded in bringing criminals to justice. Some of them have escaped."

"Yes," resumed O'Reilly, "thar's no denyin' as some of 'em escape. With all your power and cleverness, you've let a-many of 'em slip through your fingers. Thar's was the business of Lost Horse Meadow was never cleared up. Thar's was the post-office robbery at Coyote Landing, which is still a mystery. And, say, wasn't it yourself that had that same job in hand? I kinder recollect hearin' your name mentioned."

"That is so," Sergeant Silk signified. "It happened two winters ago, and, as you say, it is still a mystery, and likely to remain one."

"Don't know as I ever heard tell of that story," said the man who had spoken first, pouring some hot tea into a gallipot. His name was Bob Wilson. He was foreman of a gang of lumber-jacks.

Percy Rapson noticed that Sergeant Silk again glanced slowly round the circle of fire-lit faces, and that his gaze lingered with curious, furtive scrutiny upon the face of Eben Sharrow.
