"To your knowledge, sir, are the volcano boxes fully operational?"

"I suspect they are not. But I believe intense pressure, if not torture, is being applied to Dacian to disclose his formula for a key element in the boxes. In anticipation of his yielding, the boxes, minus the key element, are being installed. The moment he relents the element will be mass produced and set into the boxes. That is why it is imperative to find Dacian. I am almost certain he is in Singapore."

"But what makes you think Singapore is next on THRUSH'S agenda?"

"Well, it happens that Sarabando, that nice little tyrant who wiped out Tapwana, has suggested to the government of Singapore that its presence in the Federation would be most welcome. More significant, Sarabando has hinted that Singapore's refusal to come into the Federation would be regarded as an unfriendly if not hostile act.

"I will not go into the political implications now, though I'm sure you can figure most of them out for yourself. It only needs be said that those implications are worldwide. If Singapore is destroyed, no other government will resist a THRUSH demand for surrender. The volcanic weapon will simply be too potent for any sensible government to resist."

"Just one question. Why destroy Singapore if that's where THRUSH is basing its operations?"

"Singapore," Waverly explained, "is a highly strategic location. It's a valuable port and its position, in relation to the Boruvian Federation, gives THRUSH an unbroken chain of control in that part of the Pacific Ocean. So they will, if necessary, destroy it and move their headquarters elsewhere.

"You have to understand, Napoleon, that Dacian is being forced to make one of his secret elements at a time, but THRUSH is going to try to blackmail the world by claiming it has the formula and can make as many of them as it wants. And remember, if Dacian talks, THRUSH will be able to make as many operational volcano boxes as it wants. So you must proceed to Singapore at once, locate Kae Soong and Dacian, and capture or kill."

"Any hint of their specific location?"

"SINGOIL, Napoleon. That is their cable address, but we've been unable to ascertain how they pick up their messages. If you can do that, it will lead you to Kae Soong."

They signed off and Napoleon turned to April. The muscles of her jaw were rigid with tension, and her brow deeply furrowed as if she were in pain. Napoleon, thinking it was only the news from U.N.C.L.E. headquarters that was disturbing her, was about to speak when April Dancer silenced him.

He held his breath and the muscles of his legs tightened in expectation of fast movement. She was straining her ears, and her eyes darted to the left as she heard a bird screeching.

Napoleon Solo tiptoed over to her.

"What is it?" he whispered.

"My guards haven't signaled as they're supposed to, every half hour. Instead I've been hearing—it could be a macaw, but... Come this way."

She moved towards a bamboo panel in the side of the hut, which she gingerly removed. She fell to her hands and knees and crept out after looking both ways. Napoleon followed, and after exiting paused beside her. April reached under a pile of leaves and drew out a pair of machetes.

They crept along the side of the hut and peered cautiously around the corner. It was pitch black, but a dim glow from the doorway of the hut highlighted a few objects directly in front of it.

One of these was a skinny oriental with machete raised. The machete was bloody. He stood poised before the doorway, as if to strike down anyone who emerged from it. Then Napoleon caught the glint of something metallic a few feet away from the intruder, and his eyes at last made out the shape of a second one bearing what might be a grenade.

After a moment the grenade-bearer crept up to the doorway of the hut, and behind him appeared yet another oriental, a loincloth his only piece of clothing. He came to a stealthy halt.

The obvious plan was for the second to toss his bomb, and for the others to position themselves in such a way that any survivors would be slain as they emerged. Napoleon nudged April and nodded with his chin in the direction of the grenade-bearer. She was to take care of him, and he would tackle the other two.

The second intruder released the silvery object, and as he did April and Napoleon rushed them. A pop and hissing noise told them it hadn't been a grenade but a teargas canister, and as they covered the ten yards between themselves and their antagonists their nostrils caught the pungent odor of the gas seeping out of the hut.

They took the intruders completely by surprise. The bomb-thrower reached for a gun, but April's machete lashed across his shoulder. He cried out hideously as blood gouted out of the wound. The nearest oriental with the machete whirled around but had scarcely brought his blade back when Napoleon's caught him fiercely on the neck. The other man was ready for Napoleon and lashed quickly at his exposed left side, but the agent twisted out of the way and warded off a backhand swipe of the blade as the attacker tried to get him coming back.

For an instant they squared off, and it looked as if it would be an even duel. But April had now freed herself and was making ready to join the fray. In matters of world defense, two-to-one odds were not unfair. But as the oriental glanced at April, Napoleon lunged, catching him off his guard, and slashed at his mid-section.

He dropped his machete to defend the blow, and the ring of crossed blades raised a violent chatter of jungle birds. Napoleon brought his foot up and caught the swordsman in the kidney. He yelped in pain, but it was the last noise he was to make, for with immense speed Napoleon brought the razor tip of his weapon up into the man's throat, and he dropped, dying, at Solo's feet.

"We can't stay here any longer," April panted. "I must go back into the hut to destroy the radio and some documents."

"You'll come with me to Singapore," Napoleon said. "Now hurry. I don't know how many more of these guys there are, and how much time it will take for them to get here."

Out of a compartment in her belt she removed a piece of cloth as fine as silk and placed it over her nose and mouth. It was a filter which folded into a package as big as a sugar cube.

Protected against the gas, she went into the hut and came out a few minutes later with the radio and some papers. They ventured into the jungle for twenty or thirty yards, then destroyed the radio by pulling out its vitals and twisting the dials so that even if the radio were found no one would know what wavelength it was on. They buried it and burned the documents beside it. Then they care fully covered everything with dirt and leaves and headed towards the beach.

When they got there, April's guide lay slumped over a gunwale, his head almost separated from his body by a vicious machete blow, and the bottom of the boat had been stove in with heavy stones.

April Dancer ran down the beach to a point where the island cut sharply inland. As they rounded a point they stopped abruptly and spied a sailboat guarded by another oriental.

"I knew this is where it would be," she whispered, drawing out a gun and slipping a silencer over the muzzle. She aimed it at the man guarding the boat, and as the gun hissed he dropped.

"I knew they'd place their boat here to sneak up on yours," she explained once they'd shoved off and were making for open sea, "and the footsteps in the sand showed that I was right."

Napoleon took out his communicator and signaled the ship off shore to send a launch to pick them up. The cool leeward breeze carried them quickly to their destination.
