The Guesser lay on his bed, face down, his grasping fingers clutching spasmodically at the covering as his nerves twitched with remembered pain. Thirteen jolts. Thirteen searing jolts of excruciating torture. It was over now, but his synapses were still crackling with the memories of those burning lashes of energy.

He was thirty-five. He had to keep that in mind. He was thirty-five now, and his nerves should be under better control than they had been at twenty. He wondered if there were tears streaming from his eyes, and then decided it didn't matter. At least he wasn't crying aloud.

Of course, he had screamed in the nerve-burner; he had screamed thirteen times. Any man who didn't scream when those blinding stabs of pain came was either unconscious or dead—it was no disgrace to scream in the burner. But he wasn't screaming now.

He lay there for ten minutes, his jaw clamped, while the twitching subsided and his nervous system regained its usual co-ordination.

The burner did no actual physical damage; it wasn't good economics for an Executive to allow his men to be hurt in any physical manner. It took a very little actual amount of energy applied to the nerve endings to make them undergo the complex electrochemical reaction that made them send those screaming messages to the brain and spine. There was less total damage done to the nerves than a good all-night binge would do to a normal human being. But the effect on the mind was something else again.

It was a very effective method of making a man learn almost any lesson you wanted to teach him.

After a while, The Guesser shuddered once more, took a deep breath, held it for fifteen seconds, and then released it. A little later, he lifted himself up and swung his legs over the edge of his bed. He sat on the edge of the bed for a few minutes, then got up and got dressed in his best uniform.
