Half an hour later, Kiffer Samm was reading the note. He had stepped into Roysland's office and seen that it was empty. Assuming that his superior would be right back, he had sat down to wait. Then he'd seen the note.

He was halfway through it before it became perfectly clear what Roysland was doing.

"... So you may have to take over for the next twenty-five to thirty days. Naturally, I couldn't ask anyone else to take the risk.

"I think it may be a good idea if Bilford starts experimenting with subetherics in an effort to snap the rest of the boys out of this feedback loop thing. Maybe he can do it in less time.

"By the time you read this and get in a spacesuit and get out to the firing area, I will have finished the test; don't let me die of starvation, chum."

Kiffer punched at the communicator button, yelled orders into it, and grabbed a spacesuit out of the locker. By the time he reached the outer air lock, a jeep was waiting for him.

When the second jeep pulled up, Kiffer said: "You men stop at the gun emplacement and take a look at the weapon. We'll go on to the target tower and pick up Roysland."

The men nodded their agreement, and the two vehicles started rolling.

Theoretically, it was "evening," but the great, blue-white blaze of Kandoris still hung in the eternally black sky. The jeep went by the gun emplacement where the Enlissa weapon had been set up for testing. Kiffer noticed that the snout of the ugly-looking tube was aimed at the squat steel tower where the animal subjects had been exposed to its radiations.
