He was working with intangibles. He didn't know the nature of the phenomenon he had to fight. He had to extrapolate in part, guess the rest. One thing was certain, though: If he was successful in setting up a shield against the circuit, the police would arrive soon after. Arrive here.

His value to them was obvious. Through him they could make an undetected contact with the shadowy world of illegality. If that contact was cut off or if he seemed about to escape, his usefulness came to an end and they would want one more arrest while they could get it.

Once he started to work on the shield, he would have to work fast.

Jadiver went to the screen. There could be no hesitation; the decision was ready-made.

The bank robot appeared on the screen and Jadiver spoke to him briefly, requesting that his account be cleared. He scribbled his signature and had it recorded.


While waiting, he began to pack, sorting what he wanted to take. It wasn't much, some special clothing. His equipment, except for a few small tools, he had to leave. No matter. With luck, he could replace it; without luck, he wouldn't need it.

In a few minutes he was ready, but the money hadn't arrived. He sat down and nervously scrawled on a scrap of paper. Presently the delivery chute clattered and the money was in it, crisp new bills neatly wrapped, the total of his savings over the years. He stuffed the money in his pocket.

The scrap of paper was still in his hand. He started to throw it away, but his fingers were reluctant to let it go. He stared curiously at the crumpled wad and on impulse smoothed it out.

There were words on it, though he hadn't remembered writing any. The handwriting was shaky and stilted, as if he were afflicted with some nervous disease; nevertheless, it was unmistakably his own.
