"Ko had a side line," Bradley explained. "He was selling heavy water to various institutions and schools all over Asia for normal experimental purposes. He claimed to be importing it from England. That was why they were bringing so much out."

"That is also how we got interested," Keaton-Yeats said. "We got queries about more heavy water at a lower price from one of the schools that had bought Ko's product. Naturally, we knew no heavy water was coming from England, so we got interested very quickly."

"We sure dropped a monkey wrench in a gold mine," Rick said.

"Evidently," Zircon agreed. "But you haven't explained why Long Shadow and Ko are finished."

Keaton-Yeats laughed grimly.

Bradley stretched his legs out. "Easy. The story had already spread about heavy water at Korse Lenken. Ronnie and I got the good word circulating right after we received your cable from Chungking. By now all the countries he sold his story to—and that is most countries—know they've been done in the eye, as our British friend would say. Do you know the penalty for a double cross in the espionage racket?"

"A bullet, a knife, or a blunt instrument," Keaton-Yeats said. "It's as certain as tomorrow's dawn."

Bradley nodded. "Also, the lamas won't permit the two of them to remain after their wounds are healed. They are evil men, and the lamas know it. Sooner or later, they'll have to leave the mountains and enter civilization. I know their type. They might survive if they wanted to live alone in the mountains like two wolves. But they won't."

Rick shuddered. He knew from experience what it was like to be hunted. Ko and Long Shadow would be hunted by agents of a dozen countries or more once they set foot in civilization. After that, it was only a matter of time. The two couldn't escape for long.

"Now," Bradley said, "let's have the details of your trip."
