"Pop, that sounds like a lousy idea to me," I objected. "Risky, I mean. Spying on another person, watching them without their knowing, would be the surest way to stir up in me the idea of murdering them. Safest thing for me to do in that situation would be to turn around and run." "_You_ probably should," he agreed. "For now, anyway. It's all a matter of knowing your own strength and stage of growth. Me, it helps to give myself these little jobs. And the essence of 'em is that the other person shouldn't know I'm helping." It sounded like knighthood and pilgrimage and the Boy Scouts all over again--for murderers. Well, why not? Pop had seen this woman come out of the manhole a couple of times and look around and then go back down and he'd got the impression she was sick and troubled. He'd even guessed she might be coming down with Alamos fever. He'd seen us arrive, of course, and that had bothered him. Then when the plane landed she'd come up again, acting out of her head, but when she'd seen the Pilot and us going for him she'd given that scream and collapsed at the top of the shaft. He'd figured the only thing he could do for her was keep us occupied. Besides, now that he knew for sure we were murderers he'd started to burn with the desire to talk to us and maybe help us quit killing if we seemed to want to. It was only much later, in the middle of our trip, that he began to suspect that the steel cubes were jet hypodermics. While Pop had been telling us all this, we hadn't been watching the woman so closely. Now Alice called our attention to her. Her skin was covered with fine beads of perspiration, like diamonds. "That's a good sign," Pop said and Alice started to wipe her off. While she was doing that the woman came to in a groggy sort of way and Pop fed her some thin soup and in the middle of his doing it she dropped off to sleep. Alice said, "Any other time I would be wild to kill another woman that beautiful. But she has been so close to death that I would feel I was robbing another murderer. I suppose there is more behind the change in my feelings than that, though." "Yeah, a little, I suppose," Pop said. I didn't have anything to say about my own feelings. Certainly not out loud. I knew that they had changed and that they were still changing. It was complicated. After a while it occurred to me and Alice to worry whether we mightn't catch this woman's sickness. It would serve us right, of course, but plague is plague. But Pop reassured us. "Actually I snagged three cubes," he said. "That should take care of you two. I figure I'm immune." Time wore on. Pop dragged out the harmonica, as I'd been afraid he would, but his playing wasn't too bad. "Tenting Tonight," "When Johnnie Comes Marching Home," and such. We had a meal.
