It was a presentiment that the outlaw was not alone in the cabin; that he had carefully laid his plans, and that they did not include a gun fight in which he would have to face Lawler upon equal terms.
Lawler did not look around.

He kept his gaze unwaveringly upon the outlaw, knowing that if other men were in the cabin with him they were waiting for Antrim to give the word to shoot him.

Otherwise they would have shot him down when he had entered.
"Not sayin' anything, eh ?" jeered Antrim.

"Well, come a-shootin'.

You bust in here, seein' red, with a gun in your hand; an' then stand there, like you was wonderin' if you was welcome." He peered close at Lawler, his eyes narrowing with suspicion, and then, finally, with savage amusement.
"I reckon I ketch on," he sneered.
