Abruptly, painfully, Thorn woke from his impersonal absorption in the scene unrolling before him. Again it came to him, like a hammer blow, that he was not watching from the safety of a spy-hole, but was himself immediately and fatally involved. Again the urge to escape racked him—with redoubled force, because of the warning that he must now at all costs take back to World I. It was such a simple thing. Just a change of viewpoints. He had seen Conjerly accomplish it. Surely, if he concentrated his mind in the right way, it would be that other Thorn who walked forward to face the Servants and the destiny of that other Thorn's own making, while he sank back. Surely his need to warn a world would give him sufficient impetus.

But all the time he was walking toward the table. It was his dragging feet that scuffed the gray flooring, his dry throat that swallowed, his cold hands that clenched and unclenched. The eleven old faces wavered, blurred, came clear again, seemed to swell, grow gray and monstrous, become the merciless masks of judges of some fabled underworld, where he must answer for another man's crimes.

The table stopped his forward progress. He heard Clawly II say, "I am afraid that I am still very useful to you. Here is your chief enemy, brought to book by my efforts alone. He was part of our bag when he raided the local Recalcitrant headquarters last night. He escaped and took to the hills, where I personally recaptured him—the Recalcitrant leader Thorn 37-P-82."

But the Servants' reaction could not have been the one Clawly was expecting, for the old faces registered anger and alarm. "Irresponsible child!" the chairman rapped out. "Didn't you hear what Conjerly reported—that he is certain there has occurred a mind exchange between the Thorns? This man is not the Recalcitrant, but a displaced mind come to spy on us. You have provided him with what he wanted—an opportunity to learn our plans."

Thorn felt their converging hostility—a palpable force. His mind shrank back from the windows of his eyes, but, chained there, continued to peer through them.

The chairman's wrinkled hand dropped below the table. He said, "There is only one course of action." His hand came up, and in it a slim gleaming cone. "To eliminate the displaced mind before a re-exchange can be—"

Thorn was dimly conscious of Clawly II leaping forward. He heard him begin, "No! Wait! Don't you see—"

But although that was all he heard, he knew what Clawly II was going to say and why he was going to say it. He also knew why Thorn II had been able to exchange with him when Thorn II thought he was trapped and facing death on the rooftop. He knew that the chairman's action was the very thing that would nullify the chairman's purpose. At last he had found the sufficient impetus—it was staring at him down the slim, gleaming cone, leering at him even as the chains broke and his mind dropped back from the windows of his eyes into a black, dimensionless pit.

The fear of death.
