He waited.
It takes nerve and patience to wait for thirteen solid hours without making any motion other than an occasional flexing of muscles, but he managed that long before the instrument case that he held waggled a meter needle at him. The one tension-relieving factor was the low gravity; the problem of sleeping on a bed of nails is caused by the likelihood of the sleeper accidentally throwing himself off the bed. The probability of puncture or discomfort from the points is almost negligible.
When the needle on the instrument panel flickered, he got to his feet and began moving. He was almost certain that he had not been detected.
Walking was out of the question. This was a silicate-alumina rock, not a nickel-iron one. The group of people that occupied it had deliberately chosen it that way, so that there would be no chance of its being picked out for slicing by one of the mining teams in the Asteroid Belt. Granted, the chance of any given metallic planetoid's being selected was very small—but they had not wanted to take even that chance.
Therefore, without any magnetic field to hold him down, and with only a very tiny gravitic field, the detective had to use different tactics.
It was more like mountain climbing than anything else, except that there was no danger of falling. He crawled over the surface in the same way that an Alpine climber might crawl up the side of a steep slope—seeking handholds and toeholds and using them to propel himself onward. The only difference was that he covered distance a great deal more rapidly than a mountain climber could.
When he reached the spot he wanted, he carefully concealed himself beneath a craggy overhang. It took a little searching to find exactly the right spot, but when he did, he settled himself into place in a small pit and began more elaborate preparations.
Self-hypnosis required nearly ten minutes. The first five or six minutes were taken up in relaxing from his exertions. Gravity notwithstanding, he had had to push his hundred and eighty pounds over a considerable distance. When he was completely relaxed and completely hypnotized, he reached up and cut down the valve that fed oxygen into his suit.
Then—of his own will—he went cataleptic.
A single note, sounded by the instruments in the case at his side, woke him instantly. He came fully awake, as he had commanded himself to do.
