The trial was announced, and long before the appointed hour the great courtroom of that world's largest city was thronged. The hour struck. Quiet reigned. Kinnison, the Lensman, in somber gray, strode to the judge's desk and sat down behind the peculiar box upon it. In dead silence two other Lensmen approached. The first invested him reverently with the head phones; the second so enwrapped his head in black cloth that it was apparent to all observers that his vision was completely obscured.

"Although from a world far distant in space, I have been asked to try two suspects for the crime of murder," Kinnison intoned. "I do not know the details of the crime nor the identity of the suspects. I do know that they and their witnesses are within these railings. I shall now select those who are about to be examined."

Piercing beams of intense, varicolored light played over the two groups, and the deep, impressive voice went on: "I know now who the suspects are. They are about to rise, to walk, and to seat themselves as I shall direct."

They did so, it being plainly evident to all observers that they were under some awful compulsion.

"The witnesses may be excused. Truth is the only thing of importance here; and witnesses, being human and therefore frail, obstruct truth more frequently than they further its progress. I shall now examine these two accused."

Again the vivid, weirdly distorting glares of light lashed out, bathing in intense monochrome and in various ghastly combinations first one prisoner, then the other; the while Kinnison drove his mind into theirs, plumbing their deepest depths. The silence, already profound, became the utter stillness of outer space as the throng, holding its very breath now, sat enthralled by that portentous examination.

"I have examined them fully. You are all aware that any Lensman of the Galactic Patrol may, in case of need, serve as judge, jury, and executioner. I am, however, none of these; nor is this proceeding to be a trial as you may have understood the term. I have said that witnesses are superfluous. I will now add that neither judge nor jury is necessary. All that is required is to discover the truth, since truth is all-powerful. For that reason, also, not even an executioner is needed here—the discovered truth will in and of itself serve us in that capacity.

"One of these men is guilty; the other is innocent. From the mind of the guilty one I am about to construct a composite, not of this one fiendish crime alone, but of all the crimes he has ever committed. I shall project that composite into the air before him. No innocent mind will be able to see any iota of it. The guilty man, however, will perceive its every revolting detail; and, so perceiving, he will forthwith cease to exist in this plane of life."

One of the men had nothing to fear—Kinnison had told him so, long since. The other had been trembling for minutes in uncontrollable paroxysms of terror. Now this one leaped from his seat, clawing savagely at his eyes and screaming in mad abandon.
