We ought to, you know, bein' neighbors." "Friends ?" Taggart stepped back a pace and looked at Calumet incredulously, his eyes searching for signs of insincerity.

He saw no such signs, for if Calumet had emotion at this minute it was too deep to be uncovered with a glance.

But he knew from Taggart's perturbation that the latter knew him to be the man he had shot at that day in the valley.
Obviously, he had not then had any suspicion as to his identity--his surprise showed that he had not.

And his half-fearful, puzzled looks at Calumet indicated to the latter that he was wondering whether Calumet recognized him as the man who had done the shooting.
Calumet's smile was cordial, inviting, even slightly ingratiating, and watching him closely Taggart was convinced that he was not recognized.
Also he was certain that Calumet could not have learned anything of the trouble between their parents.

Yet Betty knew, and if Betty hadn't told him there must be something between them--dislike or greed on Betty's part--and a smile appeared on his face as he remembered that he had heard his father say that Calumet had been vicious and unmanageable in his youth.
