My shirt was sodden and wrinkled by this time anyway, having first been used to wipe sweat from my face and later been rolled into a ball and left on the chair when I went outside, so I used it for a cleaning rag, buffing like mad the silvered surface of the faceplate. Faceplates are silvered, not so the man inside can look out and no one else can look in, but in order to keep some of the more violent rays of the sun from getting through to the face. I buffed for a while, and then I put the fishbowl on my head and looked through it. The spot was gone, so I went over and reattached it to the rest of the suit, and then settled back in my chair again and lit a cigarette. Karpin spoke up. "Wish you wouldn't smoke. Makes it tough on the conditioner." "Oh," I said. "Sorry." So I just sat, thinking morosely about non-forged cash-return forms, and coincidences, and likely spots to hide a body in the Asteroid Belt. * * * Where would one dispose of a body in the asteroids? I went back through my thinking on that topic, and I found holes big enough to drive Karpin's claim through. This idea of leaving the body on some worthless chunk of rock, for instance. If Karpin had killed his partner--and I was dead sure he had--he'd planned it carefully and he wouldn't be leaving anything to chance. Now, an asteroid isn't worthless to a prospector until that prospector has landed on it and tested it. _Karpin_ might know that such-and-such an asteroid was nothing but worthless stone, but the guy who stops there and finds McCann's body might _not_ know it. No, Karpin wouldn't leave that to chance. He would get rid of that body, and he would do it in such a way that nobody would _ever_ find it. How? Not by leaving it on a worthless asteroid, and not by just pushing it off into space. The distance between asteroids is large, but so's the travel. McCann's body, floating around in the blackness, might just be found by somebody. And that, so far as I could see, eliminated the possibilities. McCann's body was in the Belt. I'd eliminated both the asteroids themselves and the space around the asteroids as hiding places. What was left? The sun, of course. I thought that over for a while, rather surprised at myself for having noticed the possibility. Now, let's say Karpin attaches a small rocket to McCann's body, stuffed into its atmosphere suit. He sets the rocket going, and off goes McCann. Not that he aims it toward the sun, that wouldn't work well at all. Instead of falling into the sun, the body would simply take up a long elliptical orbit _around_ the sun, and would come back to the asteroids every few hundred years. No, he would aim McCann _back_, in the direction opposite to the direction or rotation of the asteroids. He would, in essence, slow McCann's body down, make it practically stop in relation to the motion of the asteroids. And then it would simply _fall_ into the sun.
