“ If a Pinkerton man is deep in this business, we are all destroyed.""We must kill him.""Ah, it's the first thought that came to you! So it will be up at the lodge. Didn't I say to you that it would end in murder?""Sure, what is murder? Isn't it common enough in these parts?""It is, indeed; but it's not for me to point out the man that is to be murdered. I'd never rest easy again. And yet it's our own necks that may be at stake. In God's name what shall I do?" He rocked to and fro in his agony of indecision.But his words had moved McMurdo deeply. ”
