"You don't say!" The voice of the heavy man cut in with jeering irony. The gleam of his jade eyes came through narrow-slitted lids. "Well, did you take him back to the ranch for a necktie party, or did you bury him in the gulch?"

The dark young man interrupted irritably. "I'm askin' these questions, Dinsmore. Now you, young fellow—what's your name?"

"Jack Roberts," answered the cowboy meekly.

"About this rustler—would you know him again?"

The line-rider smiled inscrutably. He did not intend to tell all that he did not know. "He was ridin' a sorrel with a white splash on its nose, white stockin's, an' a bad hoof, the rear one—"

"You're a damn' liar." The words, flung out from some inner compulsion, as it were, served both as a confession and a challenge.

There was a moment of silence, tense and ominous. This was fighting talk.

The lank man leaned forward and whispered some remonstrance in the ear of the young fellow, but his suggestion was waved aside. "I'm runnin' this, Gurley."

The rider for the A T O showed neither surprise nor anger. He made a business announcement without stress or accent. "I expect it's you or me one for a lickin'. Hop to it, Mr. Rustler!"

Roberts did not wait for an acceptance of his invitation. He knew that the first two rules of battle are to strike first and to strike hard. His brown fist moved forward as though it had been shot from a gun. The other man crashed back against the wall and hung there dazed for a moment. The knuckles of that lean fist had caught him on the chin.
