I didn't bother to put my shirt back on first, and that was a mistake. The temperature inside an atmosphere suit is a steady sixty-eight degrees. That had never seemed particularly chilly before, but after the heat of that dome, it seemed cold as a blizzard inside the suit.
I went on out through the airlock, and moved as briskly as possible in the cumbersome suit, while the sweat chilled on my back and face, and I accepted the glum conviction that one thing I was going to get out of this trip for sure was a nasty head cold.
I went over to the X first, and stood looking at it. It was just an X, that's all, shakily scrawled in yellow paint, with the initials "J-A" scrawled much smaller beside it.
I left the X and clumped away. The horizon was practically at arm's length, so it didn't take long for the dome to be out of sight. And then I clumped more slowly, studying the surface of the asteroid.
What I was looking for was a grave. I believed that Karpin was lying, that he had murdered his partner. And I didn't believe that Jafe McCann's body had floated off into space. I was convinced that his body was still somewhere on this asteroid. Karpin had been forced to concoct a story about the body being lost because the appearance of the body would prove somehow that it had been murder and not accident. I was convinced of that, and now all I had to do was prove it.
But that asteroid was a pretty unlikely place for a grave. That wasn't dirt I was walking on, it was rock, solid metallic rock. You don't dig a grave in solid rock, not with a shovel. You maybe can do it with dynamite, but that won't work too well if your object is to keep anybody from seeing that the hole has been made. Dirt can be patted down. Blown-up rock looks like blown-up rock, and that's all there is to it.
I considered crevices and fissures in the surface, some cranny large enough for Karpin to have stuffed the body into. But I didn't find any of these either as I plodded along, being sure to keep one magnetted boot always in contact with the ground.
Karpin and McCann had set their dome up at just about the only really level spot on that entire planetoid. The rest of it was nothing but jagged rock, and it wasn't easy traveling at all, maneuvering around with magnets on my boots and a bulky atmosphere suit cramping my movements.
And then I stopped and looked out at space and cursed myself for a ring-tailed baboon. McCann's body might be anywhere in the Solar System, anywhere at all, but there was one place I could be sure it wasn't, and that place was this asteroid. No, Karpin had not blown a grave or stuffed the body into a fissure in the ground. Why not? Because this chunk of rock was valuable, that's why not. Because Karpin was in the process of selling it to one of the major companies, and that company would come along and chop this chunk of rock to pieces, getting the valuable metal out, and McCann's body would turn up in the first week of operations if Karpin were stupid enough to bury it here.
