The only way a man could escape was to have some means of communication so that friends could come to his aid. Paul's only method of contact was the Z-wave.

They did let Paul tinker, and they even let him work, but they would not let him near Z-wave equipment that was connected with the radio beacon. Toby Morrow helped Paul with calculations and theory, being the only one among the prisoners who had done any work with Grayson.

Morrow, of course, had been picked up by Westlake's crew on the planet at the other end of this leg of the Galactic Survey Link, along about the same time that Paul had been grabbed near G.S.C. 311; IX. It was apparent without saying anything about it that Westlake's gang had been working with the Z-wave in the hope of establishing the validity of Paul's statements.

But so far, they had not been able to make contact apparently, and Paul had not been able to, either.

So as the days passed into weeks, Paul once more reconstructed his map of the Galactic Survey and connected this star with that, and the other with the fourth. It was beginning to fill in, now.

Paul viewed it with interest, occasionally wondering who was checking the beacons in his place.

But it was filling in, and it reminded him somewhat of that game played with dots, in which each player takes a turn connecting two dots with a line, the idea being to complete squares yourself while preventing your opponent from completing any. Usually the first several moves are drawn here and there with no particular pattern. Then as the game progresses, more and more lines connect more and more dots until it is impossible to draw a line between two dots that does not also connect two other, previously drawn lines.

The galactic map is far from a square, otherwise all of the lines would have terminated at the same time.

Even so, there were whole lengths of solid line, zig-zag across space between the nearer stars that would make a solid connection between stations thirty to fifty light years apart. And every week saw another connection made, and each connection completed the connection between isolated groups. It took on a maze-like appearance; Paul thought that if it were stretched out and the collateral paths were added, the thing would have reached between Terra and Neoterra and half-way back.

So Paul added to his map as the weeks went on until there were only a few open stretches between Sol and Neosol. He thought ruefully that it was a damned shame that the whole Galactic Network would be completely closed before he got a chance to try the Z-wave. Instead of starting with one contact and working his way across, the first interstellar contact via Z-wave might well be a complete attempt between the two planets, one hundred and forty light years apart.
