Forever We Die!

Rhodes faced the agonies of alien torture because he knew the secret which held an entire world in bondage. It was a secret proclaiming—

The guard spat in Phil Rhodes' food bowl, closed the grate, and trudged away down the stone-walled corridor.
Darkness returned to the narrow, coffin-shaped cell. Rhodes reached for the bowl of gruel. It was tepid, not hot. The cell was very cold. In the square of light admitted briefly when the grate had been opened, Rhodes had seen the big, unkempt guard's breath, a puff of smoke on the cold air. He had also seen the guard hack spittle into the bowl of gruel.
It was no whim on the guard's part. Rhodes grinned wryly, and realized he was doing so, and encouraged his facial muscles in the act. Nothing around here was a whim. Absolutely nothing. It was all part of a plan, and the purpose of the plan was to break Rhodes.
Given: one Earthman.
Problem: to degrade him by subtle psychological torture.
Purpose: a big, fat question mark which, by itself, was almost enough to drive Rhodes crazy.
He ate the gruel. He held his breath and got it down somehow, got it down because he had to.
It had been some time since the last question period, and Rhodes expected to be summoned momentarily. Why me? he thought for the hundredth time. That was part of it, too. Why Rhodes? He was only a student at the Earth University at Deneb III, here on Kedak now—that was Deneb IV—to do field work in extra-terrestrial anthropology. And the Kedaki had come for him one night, how long ago? Rhodes had no idea how long it was, and that was part of the plan too. His sleep was irregular, usually disturbed by one or another of the guards as part of the overall pattern of psychological torture.
Rhodes began to shiver. It was growing suddenly cold. Naturally, that was no accident. The cell was very small and so shaped that Rhodes could neither recline fully nor stand up without jack-knifing his spine. Obviously, he couldn't engage in much physical activity to keep warm. The Kedaki knew this: it was part of the maddening plan.
