Quillan nodded. "That's what it looks like."

"But he had two grenades!" Orca burst out. "He had sprayguns! How could it get him that way?"

"Brother," Quillan said, "grenades won't help you much if you don't spot what's moving up behind you!"

Orca glared speechlessly at him. Ryter said, "All right! We've lost another man. We're not going to lose any more. We'll station no more guards on the fifth level. Now, get everyone who isn't on essential guard duty to the main room, and split 'em up into life-detector units. Five men to each detail, one to handle the detector, four to stay with him, guns out. If the thing comes back to this level, we want to have it spotted the instant it arrives. Orca, you stay here—and keep your gun out!"

The men filed out hurriedly. Ryter turned to Quillan. "Were you able to get the cubicle baited?"

Quillan nodded. "Kinmarten figured out how the thing should be set for the purpose. If the Hlat goes in after the sea beef, it's trapped. Of course, if the hunting it's been doing was for food, it mightn't be interested in the beef."

"We don't know," Ryter said, "that the hunting it's been doing was for food."

"No. Did you manage to get the control device from Cooms?"

Ryter shook his head. "He's refused to hand it over."

"If you tried to take it from him," Quillan said, "you might have a showdown on your hands."
