"There's something here that's mighty mysterious," said he, shaking his head. "This Juan Morisco must be a hard citizen or McKibben wouldn't have nabbed him. And what was the girl doing with Morisco, tied to the wagon like she was? Got to make her talk, King. You seem to have more influence over her than any one else. She's too young to have much strength of will, and I think she'll tell you everything if you keep trying to make her."

"That's where you're wrong, doctor," said Matt. "From what I've seen of her I'll bet she won't say a word. Rags has got a reason for keeping back what she knows, and she'd let you kill her before she'd breathe a whisper."

"Well, I hear McKibben is giving Juan Morisco the third degree. If Morisco can stand that, he's a better man than I think he is. One way or another, the truth about that girl is bound to come out."

The doctor got into his buggy and drove off. Matt stood at the gate for a few moments, looking for Clip; but, as he could see nothing of him, he went back into the house.

Rags was asleep. Susie, who sat beside the couch, looked at Matt and laid a finger on her lips. Matt tiptoed out through the kitchen to the back of the house. Chub was sitting in a chair, tilted back against the wall.

"What's old Sawbones got to say, pard?" he asked.

"Not much hope for Rags, Chub," said Matt gravely.

"Too bloomin' bad!" muttered Chub, "but mebby old pills-an'-physic has made a wrong guess."

"Of course, there's a chance that he's off his reckoning. Wish I knew why Rags won't tell us anything about herself, or about those two greasers who had her tied to the wagon."

"She's a nervy little piece! Mebby she'll tell you, though, if you give her time. You seem to make a hit with all the girls, Matt, little an' big, an' Rags has taken to you like a Piute squaw to a string of glass beads."
