"Most of the stuff that's peddled nowadays is doctored," Nolan replied, with the air of one who knows. "When it isn't White Mule, it's likely to be something worse. That's one of the chief reasons why I'm fighting it. If they only peddled decent whisky it wouldn't be so bad, Ryan. But it's rank poison. I've seen so many go stone blind--or die--that it makes me pretty savage sometimes. So now I'll coach you in the part you're to play as hootch runner; and to-morrow you can start for Los Angeles." Casey did not answer. He felt absently for his pipe, filled and lighted it and went out to sit on the doorstep in gloomy meditation while he smoked. Returning to Los Angeles, even without a bootlegger's load, was not a matter which Casey liked to contemplate. He would have to face the Little Woman if he went back; either as a deliberate liar, who lied to his wife to gain the freedom he might have had without resorting to deceit, or as the victim once more of crooks. Casey thought he would prefer the accusation of lying deliberately to the Little Woman, though it made him squirm to think of it. He wished she had not openly taunted him with getting into trouble and needing her always to get him out. He would like to tell her that he was now working for the government. The secrecy of his mission, the danger it involved, would impress even her amused cynicism. But the very secrecy of his mission in itself made it impossible for him to tell her anything about it. Casey would not admit it, but it was a real disappointment to him that he could not wear a star on his coat. All that day and evening he was glum, a strange mood for Casey Ryan. But if Mack Nolan noticed his silence, he gave no sign. Nolan himself was wholly absorbed by the business in hand. The success of this plan meant a good deal to him, and he told Casey so very frankly; which lightened Casey's gloom perceptibly. Casey was to drive to Los Angeles--even to San Diego if necessary--and return within a week, unless Nolan's hopes were fulfilled and Casey was held up and highjacked. If he were apprehended by officers who were honestly discharging their duty, Casey was to do thus-and-so, and presently be free to drive on with his load. If he were highjacked (Casey gritted his teeth and said he hoped the highjacker would be Smiling Lou), he was to permit himself to be robbed, worm himself as far as possible into their confidence and return for further orders. If Mack Nolan should chance to be absent from the cabin, then Casey was to wait until he returned. And Nolan intimated that hereafter the making of moonshine might be a part of Casey's duties. Then, without warning, Mack Nolan struck at the heart of Casey's worry.
