Bertie grunted noncommittally.
"Okay. Now like I told you, shoot when I give you the mental signal. You'll see the ones."
"Uh-huh," Bertie said, chewing complacently.
"Go on downstairs then."
Bertie hunkered forward and leered at Parr. "Sure. Sure."
"Hurry the hell up," Kal said.
Bertie shuffled to the door, opened it, left the room.
Parr swallowed uneasily.
Kal chuckled. "Good one, Bertie. Useful. Damn this pressure. Glad I brought him. They won't be looking for an Earthman, eh? So when they try to come in here after us, he'll drop 'em, eh?"
Parr wet his lips. "They're getting nearer."
