"Tinker?" he asked softly.

"Here ... and still going," she said. "Ready?"

Cal swallowed deep. "Yes," he said hoarsely.

"I ... I can't."

"You must! How I wish we had a duplicator."

Cal shuddered. "Never."

"Well, I could show you how it's done on the duplicate, and then the duplicate could fix me up."

Cal gritted his teeth, "And which one would I dispose of? No, Tinker. It's bad enough this way!"
