Corrigan had left no one on guard.

"It's a cinch," Levins declared as they dismounted from their horses in
the shelter of a shoulder of the butte, about a hundred yards from where
the corrugated iron building, nearly complete, loomed somberly on the
level. "But if they'd ever get evidence that we done it--"

Trevison laughed lowly, with a grim humor that made Levins look sharply at
him. "That abandoned pueblo on the creek near your shack is built like a

"Plenty. Oh, you're curious, now. But I'm going to keep you guessing for a

spent looking about her. Her own breath was coming sharply, sobbing in her
throat, but it was more from excitement than from the hazard and labor of
the ride, for she had paid little attention to the trail, beyond giving
the horse direction, trusting to the animal's wisdom, accepting the risks
as a matter-of-course. It was the imminence of violence that had aroused
her, the portent of a lawless deed that might result in tragedy. She had
told Mrs. Levins that she was doing this thing for _her_ sake, but she
knew better. She _did_ consider the woman, but she realized that her
