Tom Barden sat in an easy-chair, relaxing. He was watching the others, who were glaring at one another and trying to conceal their thoughts. Lanthar—he of Procyon—and Grenis of Sirius both knew that the Terran who sat there so easily was not fooling.

"Now," said Barden, "what's the story? I've told you what happened and why I'm angry. This warfare must stop, and Sol, too, must be protected. Only by complete agreement can all three of us occupy the sky in safety. Otherwise, there may be but two of us—and perhaps only one. You—Lanthar—what do you know of the space motor?"

"I'll tell," said the one from Procyon. "I've been in disagreement with the plan but outvoted. We discovered it and its danger. We'd have worked upon it, but we could not permit it to be used in space because of attack. We could not try it on a planet because of the danger. Remember, we were at war and could afford to take no chances. There was a large faction who outvoted me—and then they permitted its theft from a false laboratory. It is amusing, Terran, to go into the full details of how this laboratory was set up, run, and finally thefted. We actually treated it as though it held one of our high secrets, but we were lax only in the total number of guards we used. They—succeeded.

"The purpose of this was to permit them to try it out. That would mean their destruction. I've insisted that a dead enemy is of no value—"

"We follow your reasoning, all of us," said Barden. "And go further. We state that an enemy is a total loss per se and we avoid the expense. Now, Grenis, you stole the plans?"

"We did," said the Sirian. "But there was something wrong. Not only did we steal the plans, but we inspected their plant. While they were setting up their laboratory they forgot to include some means of accepting and dissipating enough transmitted power to make the work look real. There was a quite large discrepancy between the power used and the power we calculated would be needed to carry on such a program. So we became suspicious—which started when we were able to penetrate the place in the first place.

"What we found was interesting," said the Sirian. "But we were suspicious. We studied it carefully, and it seemed perfect. But, Terran, came again the suspicion. For if this were so perfect, why weren't they using it?

"Because it might be a trap," he went on. "And like he and his, we dared not establish a space-laboratory because of the fear of attack. So we were completely stopped."

Lanthar grunted. "So he and his bunch went to work on a method of contacting other people at a great distance," he said. "It took them a long time and they were without success at all until they succeeded in contacting you."

"That is correct," said Grenis, making an apology. "We have detectors capable of working on the gravitic effects. A nova would disrupt both the magnetic and the gravitic levels sufficiently to warn us immediately. And we knew that any race who was not suspicious of an enemy would try it—"
