VI.

Gradually and so insidiously that the Velantian's dire warnings might as well never have been uttered, the scene changed. Or rather, the scene itself did not change, but the observers' perception of it slowly underwent such a radical transformation that it was in no sense the same scene it had been a few minutes before; and they felt almost abjectly apologetic as they realized how unjust their previous ideas had been.

For the cavern was not a torture chamber, as they had supposed. It was, in reality, a hospital, and the beings they had thought victims of brutalities unspeakable were, in reality, patients undergoing treatments and operations for various ills. In proof whereof the patients—who should have been dead by this time were the early ideas well-founded—were now being released from the screenlike operating theater. And not only was each one completely whole and sound in body, but he was also possessed of a mental clarity, power, and grasp undreamed of before his hospitalization and treatment by Delgon's super surgeons!

Also, the intruders had misunderstood completely the audience and its behavior. They were really medical students, and the beams which had seemed to be devouring rays were simply visibeams, by means of which each student could follow, in close-up detail, each step of the operation in which he was most interested. The patients themselves were living, vocal witnesses of the visitors' mistakenness, for each, as he made his way through the assemblage of students, was voicing his thanks for the marvelous results of his particular treatment or operation.

Kinnison now became acutely aware that he himself was in need of immediate surgical attention. His body, which he had always regarded so highly, he now perceived to be sadly inefficient; his mind was in even worse shape than his physique; and both body and mind would be improved immeasurably if he could get to the Delgonian hospital before the surgeons departed. In fact, he felt an almost irresistible urge to rush away toward that hospital instantly, without the loss of a single precious second. And, since he had had no reason to doubt the evidence of his own senses, his conscious mind was not aroused to active opposition. However, in his subconscious, or his essence, or whatever you choose to call that ultimate something of his that made him a Lensman, a "dead, slow bell" began to sound.

"Release me and we'll all go, before the surgeons leave the hospital," came an insistent thought from Worsel. "But hurry—we haven't much time!"

VanBuskirk, completely under the influence of the frantic compulsion, leaped toward the Velantian, only to be checked bodily by Kinnison, who was foggily trying to isolate and identify one thing about the situation that did not ring quite true.

"Just a minute, Bus. Shut that door first!" he commanded.

"Never mind the door!" Worsel's thought came in a roaring crescendo. "Release me instantly! Hurry, or it will be too late, for all of us!"
