"You're a native. You know more about it than we could ever find out in the time we have, and you have a scientific background. You must know approximately where the largest uranium deposits are, for instance, and the main sources of radioactive isotopes. Yet you refuse to verify our information, or correct it if it's wrong."

"It's up to you, sir," Makvern said, shrugging.
"No opinion at all?"
"None."
"That's not like you, Makvern."
"It's impossible to have any opinion of value concerning the advisability of—ah—questioning a man I don't know at all. I have no idea of his limits. If they're easily reached, fine. If not, he's likely to die before you know it."
