Only Joe Montgomery would suffer--Joe Montgomery, penniless and friendless, a cur in the gutter for any decent man to kick! He passed the back of his hand across his face.
"It's a hell of a world and be damned to it!" he muttered hoarsely under his breath.
"You must make it clearer to me than this!" said the judge impatiently.
Montgomery seemed to undergo a brief but intense mental struggle, then he blurted out: "Boss, I lied when I said it was North I seen come over old man McBride's shed that night!" "Do you mean to tell me that you perjured yourself in the North case ?" asked the judge sternly.
"Sure, I lied!" said the handy-man.

"But Andy Gilmore was back of that lie; it was him told me what I was to say, and it's him that kept houndin' me, puttin' me up to say more than I ever agreed to!" He slouched nearer the judge.

"Boss, I chuck up the whole business; do you understand?
I want to take back all I said; I'm willin' to tell the God A'mighty's truth!" He paused abruptly.

In his excitement he had forgotten what the truth meant, what it would mean to the man before him.
