The face of the lieutenant was that of a frightened tiger from the depths of the Assam jungles. The muzzle of the gun swung to cover the sleeping soldier. A split second passed during which this Asian was on the verge of joining his ancestors.

Realizing finally that this man could not be held accountable for his inability to stay awake, the lieutenant held his fire. He jerked up his head to stare around the room. His face was that of a tiger who suspects it has been caught in a trap but is not yet certain of the nature of the device it has been snared in. His eyes came to focus on Cal.

"I—I swear—" The ragged man's voice was a thick mutter that did not convey much meaning. Cal was sleepy too!

"What have you done here?"

"I—nothing. I have done nothing—and I know nothing—I am as surprised as you."

"You're a liar!"

"No. Telling truth—" Cal's head had sagged downward toward his chest and his voice was getting thicker and more groggy. With an effort of will, he snapped his head up. "I—don't know. Something.... Yes! Never heard of anything like it before.... Hell, lieutenant, it's getting me too!"

Cal's head sagged forward on his chest. "So sleepy ... so tired ... gotta take a nap...." His knees sagging, Cal lay down on the floor. He cuddled his head on one arm.

The lieutenant spoke, but the grunt that came from his lips was not a growl. Soon, he, too, was fast asleep.

Kurt and Nedra were the only two people who were able to remain awake. The nurse was making desperate efforts to resist this strange sleepiness. Swaying on her feet, she turned toward Zen. He caught her in his arms.
