Illya's face showed he had come back with the facts first, but Napoleon spoke. "Dr. Edward Dacian. Scientist, working at some laboratory in Texas. Oh yes, I remember. He was experimenting with the application of laser technology to mining operations." Napoleon turned to Illya for a hand. What one didn't know, the other usually did.

"It wasn't only mining," the slim blond Russian said. "It was drilling as well. He was using lasers to penetrate the earth's surface. I think an oil concern had him under contract."

Although Waverly had the information at his fingertips, he usually refrained from coaching his agents during briefing sessions. On the grounds that an agent learns to swim if the alternative is sinking, he always let his people flounder and thrash, using their memory and wits to get them out of trouble. If he gave them too many cues he would only injure them in the long run, for they would come to rely more on him than on their own resources. Thus he held his tongue as his two star agents batted Dacian's life back and forth until they got the facts straight.

"No," Napoleon Solo contradicted his companion, "it wasn't oil. I think it was—yes, it definitely was an electric power company."

Illya's normally cool facade became animated with the excitement of recognition. "Right! Now I remember. This power and light combine had set Dacian to work to drill deep into the earth's mantle with his laser instrument. As they penetrated it they'd of course approach the hot material in the core. At a certain level the heat would be so intense it would turn water to steam. So if Dr. Dacian were to drill, say, on the ocean floor or through the bed of a big river, the hole would be perpetually filled with water, which in turn would be converted into steam, like those geysers in Yellowstone Park."

"And the company that hired Dacian saw this steam as a simple and cheap mode of energy," Napoleon added. "All they had to do was harness it to generate all the power they needed."

Waverly's bloodhound face wrinkled in the semblance of a dim smile of appreciation. "Very good, gentlemen. But there is one major fact you've been withholding."

Napoleon Solo grinned. "We've saved the best for last."

"Well, get on with it; I'm a busy man," their chief growled.

"Dacian disappeared about six months ago," Napoleon said.

The trio held silence for a few moments as the threads Waverly had been weaving came together to form a distinct and sinister pattern. It fell on Napoleon to summarize the situation.

"So you believe," he said to Waverly, "that THRUSH abducted Dacian, and somehow coerced him to create for them the device he'd been working on in Texas. And now THRUSH is using that device to blackmail governments. The first one to feel the blow was Tapwana."

"That's correct. The volcano that preceded Tapwana's, the one on that unpopulated island, was probably experimental. Having proved the device worked, they applied it to Tapwana. I don't believe that Tapwana was that vital to THRUSH politically; rather, THRUSH used the device to warn other governments of its immense power in the form of Dacian's device.

"I have no doubt that every government in the world can expect soon to hear from THRUSH with a blackmail message. The forces on our planet, as a result of this situation, are distinctly unbalanced, and must be restored as soon as possible. So let me give you your assignments."

He turned to Napoleon first. "I would like you to proceed to Borua, the island where dictator Sarabando reigns. Fortunately for us April Dancer and Mark Slate just completed an assignment in Hong Kong three days ago. I might add it was eminently successful," Waverly said with a smile of gratification. "Mark left immediately for London, but April, after checking with me, had plans to stay on at the Hong Kong Hilton for a short rest which she highly deserved."

Waverly's expression changed suddenly. "However, before the poor girl had a chance to relax, we received the shocking news that our U.N.C.L.E. director of operations in Singapore, Harry Gray, had been mysteriously stabbed to death. This is a great loss to us, for as you two know, Gray was a key agent in our Indonesian area. And most important now, Gray had valuable in formation on the Boruvian Federation and the scientist Dr. Dacian. Because of this crisis in the Singapore headquarters, April has been ordered to go there. She's been helping Joe Kingsley, who worked under Harry Gray, and now she's investigating in Borua. She knows enough for you to proceed, I believe, in your usual sagacious manner, Mr. Solo."

Napoleon Solo gazed at Illya and smiled broadly. "I'll be looking forward to working with one of our best girl agents, April Dancer. Glad she took over for Harry."

Waverly handed a neat typewritten report to Solo. "She's informed fully about the THRUSH threat in the Boruvian Federation. Study this en route."

"Yes sir. So we are to try to track down Dr. Dacian and his machine?"

"Yes. It will be difficult and dangerous. If Dacian has been eliminated by THRUSH, get all copies of his formula, all volcano devices in existence. Concentrate, too, in discovering anyone there who knows the technique of Dr. Dacian's treacherous device. In this end, Mr. Solo, I believe luck may be with us."

"How so?"

"I don't believe Dacian has spilled the formula. If he had, we'd have gotten our blackmail notices long ago. He is obviously being coerced to make one machine at a time, and is doing so reluctantly, slowly. But THRUSH will get that formula sooner or later, and you'll have to work fast.

"Illya," he said, turning to Napoleon's colleague, "you are to proceed to Gulf Coast Power and Light laboratories in Texas. There you are to work with the officers and scientists, both to learn everything you can about the process Dacian was working on, and, if you can, about suspicious persons who might give us some clue as to Dacian's present unknown whereabouts.

"In addition, I want you to work with them to develop a device which can detect Dr. Dacian's machine from a distance and destroy it. You have Gulf Coast's promise of full cooperation to say nothing of our government's."

The agents exchanged glances, then turned their eyes back to Waverly's, who gazed at them sadly. "You're to report to me on any development, large or small, and as soon as we're on the trail of Dacian and his abductors I'll have you join forces to make the kill. Any questions?"

Waverly's question was answered with silence.

"Very well, then," he said, turning the files over to them, "be on your way. You haven't a moment to lose. Study this information immediately, then speak to Transportation about the arrangements that have been made for your departure."

Napoleon Solo and Illya Kuryakin whirled on their heels and retreated from Waverly's office.

"Volcanoes," Illya muttered laconically.

"One of our hotter assignments," Napoleon said.

ACT II

ISLES OF HELL

SOUTHEAST of Celebes in the Indonesian Islands is the Banda Sea, a rich blue expanse of water that might be described as a lake within an ocean. It lies, almost like a stupendous crater, in the center of a crescent of volcanic islands to its south and a semi-circle of massive string of isles and atolls to the north.

Because of its partially protected position the sea escapes the rough handling of open ocean storms, but typhoons sweeping it in the season radiate their havoc from its axis and dash immense destructive waves on the shores of the many islands around its perimeter.
