you any good—" Whonk winked broadly. "I must take my revenge!" he roared. "I shall test the texture of the Soft One! His pulped remains will be scoured up by the ramp-washers and mailed home in bottles!" Retief whirled at a sound, caught up with the scuttling Yith fifty feet away, hauled him back to Whonk. "It's up to you, Whonk," he said. "I know how important ceremonial revenge is to you Fustians. I will not interfere." "Mercy!" Yith hissed, eye-stalks whipping in distress. "I claim diplomatic immunity!" "No diplomat am I," rumbled Whonk. "Let me see; suppose I start with one of those obscenely active eyes—" He reached.... "I have an idea," said Retief brightly. "Do you suppose—just this once—you could forego the ceremonial revenge if Yith promised to arrange for a Groaci Surgical Mission to de-carapace you elders?" "But," Whonk protested, "those eyes! What a pleasure to pluck them, one by one!" "Yess," hissed Yith, "I swear it! Our most expert surgeons ... platoons of them, with the finest of equipment." "I have dreamed of how it would be to sit on this one, to feel him squash beneath my bulk...." "Light as a whissle feather shall you dance," Yith whispered. "Shell-less shall you spring in the joy of renewed youth—" "Maybe just one eye," said Whonk grudgingly. "That would leave him four." "Be a sport," said Retief. "Well." "It's a deal then," said Retief. "Yith, on your word as a diplomat, an alien, a soft-back and a skunk, you'll set up the mission. Groaci surgical skill is an export that will net you more than armaments. It will be a whissle feather in your cap—if you bring it off. And in return, Whonk won't sit on you. And I won't prefer charges of interference in the internal affairs of a free world." Behind Whonk there was a movement. Slock, wriggling free of the borrowed carapace, struggled to his feet ... in time for Whonk to seize him, lift him high and head for the entry to the Moss Rock.
