The brakie heard this recital with the keenest interest, nodding from time to time."What beats me, Lefty," he said at the end of the story, "is why you didn't knife into the fightyourself and take a hand with Donnegan"At this Lefty was silent. It was rather the silence of one which cannot tell whether or not it isworth while to speak than it was the silence of one who needs time for thought."I'll tell you why, bo. It's because when I take a trail like that it only has one end I'm going tobump off the other bird or he's going to bump off me"The brakie cleared his throat"Look here," he said, "looks to me like a queer thing that you're on this train""Does it" queried Lefty softly "Why?""Because Donnegan is two cars back, asleep.""The devil you say!"The brakie broke into laughter"Don't kid yourself along," he warned. "Don't do it. It ain't wise-with me.""What you mean?""Come on, Lefty. Come clean. You better do a fade off this train.""Why, you fool-""It don't work, Joe. Why, the minute I seen you I knew why you was here. I knew you meant tocroak Donnegan.""Me croak him? Why should I croak him?""Because you been trailing him two thousand miles. Because you ain't got the nerve to meet himface to face and you got to sneak in and take a crack at him while he's lying asleep. That's you, LeftyJoe!"He saw Lefty sway toward him; but, all stories aside, it is a very bold tramp that cares forargument of a serious nature with a brakie. And even Lefty Joe was deterred from violent action. Inthe darkness his upper lip twitched, but he carefully smoothed his voice.
