The amplifier coughed and went out. Dargon left the control booth.

"Napoleon," Illya said to the emptiness, "I hope you're grateful."

There was a faint clink of the chain as Illya accidentally moved and set himself swinging again. His arms felt hot and swollen. For the first time, he groaned in agony.

Time became unreal. Fear became the true reality. Illya tried not to dwell on the very thought which Dargon had planted. It was impossible.

The solitude and pain created dread. The dread induced a kind of reverse anticipation. Illya found himself hanging stone-still and staring at the heavily gasketed door, wondering, how soon will it open? How soon will the booth be occupied again? How soon? How soon?

His head jerked up. He glanced around the egg-shaped room. The lights had been lowered. The chamber had a twilight dimness. It felt like the middle of the night.

Illya's arms were totally numb. He had feeling from his waist down, but precious little. He realized that he must have passed out for a time. Cautiously he turned his head. The small movement started him swinging. His arms throbbed and ached.

Mei's eyes were open. She stared at him dully, too tortured to speak.

"I think it's night," Illya croaked. "I think they're leaving us alone."

"Until the morning," the girl breathed through puffy lips.

"Napoleon will reach Hong Kong. He'll do something to help us."

"No one can help us. At least I shall die with - a brave friend."

The oval door clanged back. Dr. Dargon stepped over the sill. He carried a pistol in one hand and what appeared to be a black and white glossy photograph in the other.

Dargon approached and peered up at them. "Ah, you're awake. It is late, and other matters prevented us from returning our attentions to you this evening. However, I felt you must receive this vital news. It is my pleasure to inform you that your friend Solo has run out of rope. He is dead."

Illya's heart missed one pumping beat. "You're lying."

Dargon shrugged. "Well, for all practical purposes he is dead. Very likely General Weng has already attended to it. Solo's assault on the plane failed. Here, see for yourself. This picture was just transmitted from the electrophoto unit in the aircraft."

Horrified, Illya recognized the subject of the photo. Napoleon Solo lay unconscious on a carpet. A rifle had fallen at his side. Background details suggested the interior of an airplane. Illya squinted to see the photo better. It was untouched. Solo's face looked chalky, lifeless.

Dargon said: "I felt these tidings would help guarantee cheerful thoughts until we return to visit with you again. I am sure - aargh!"

The sudden slam of Illya's feet against the sides of Dargon's neck made the doctor squeal. In one burst of ebbing strength, Illya had swung forward and smacked his heels together. His feet held the scrawny flesh above Dargon's collar in a tight grip. Adrenalin pumping into Illya's body gave him the tiny extra measure of strength he needed.

Dargon struggled feebly and dropped his gun. It clattered away.

"The keys," Illya panted. "Throw the keys up toward my hands or I'll break your neck."

Dargon peered into Illya's face. What he saw there, coupled with his own innate cowardice, convinced him that temporary cooperation was the wisest course. He gulped in genuine terror.

Illya used every bit of his considerable strength to maintain the pressure on Dargon's neck. He said through tightly-locked teeth, "If you make a single move in the direction of that gun, I will cut off your circulation and kill you with the pressure of my foot. U.N.C.L.E trains its people in neurophysiology. My right heel is resting in a potentially fatal spot. You may be able to jerk away, but you will be dead by the time you reach your gun. Now throw the keys at my hands, and very carefully. You have only one chance.

I hope your aim is accurate."

Dargon's eyes grew saucer-like. "It's a - a cheap, filthy bluff."

"Then you have nothing to lose by submitting your conviction to the scientific method. Shall we run a little test, Doctor?"

He did no know how much longer he could maintain his pressure. But Dargon gave in. He clawed the keys from his smock. He licked his lips and threw them high.

Illya released Dargon's neck. The doctor had aimed to miss, as Illya knew he would. Illya

wrenched his body forward in a tremendous tumbler's kick-out. That way he managed to bring his hands into a position to catch the keys as Dargon dove for the gun on the floor.

Illya had to work by feel, twisting one key after another into the lock mechanism which he had previously located in the six-inch bar between the manacles. Dargon got hold of the gun. He whirled. Illya found the right key. The manacles snapped open. He dropped and hit the floor as Dargon's shot thundered.

Like a cat Illya raced for the scientist as Dargon tried to level the gun for another shot. His hand trembled like a wind-lashed bough.

"Help, help!" Dargon piped in ludicrously reedy tone. Then Illya chopped him brutally in the throat. Dargon collapsed.

"The shot!" Mei exclaimed. "The guards will come -"

"Possibly not," Illya breathed. "Unless I am wrong, a test chamber like this is amply insulated. Wait here."

He snatched the keys and ran out through the oval door. In moments, he had entered the control booth from an empty corridor. He located and activated the winch. Mei was soon on the floor, covered with several yards of chain. More was coming down on top of her every second as Illya sprinted back in and unlocked her. His eyes were grim.

"We must assume Napoleon is dead, Mei. Therefore this foul lump -" He prodded the just-awakening Dargon with the pistol. "- is going to be our tour escort. He is going to show us how to get out of here, and guide us to Hong Kong."

On hands and knees the stupefied, terrified Dargon stared up into the muzzle of Illya's gun.

Illya dragged Dargon to his feet. "Show us the scenic exit route. And quickly!"

Four

Napoleon Solo wakened with a buzzing skull and a mouth which tasted like a mixture of camphor oil and woolen athletic socks.

Above him soared a pastel ceiling. He turned his head. A rich wine-colored sea of nylon carpeting stretched away to a pair of white doors with gold hardware. Dotted here and there like islands upon the carpet sea were assorted pieces of furniture in the style Solo characterized as Assembly Line Modern. White, and upholstered in plastic.

Cautiously Solo stood up. In a couple of minutes the Oriental gong players inside his temples suspended their music.

The floor tilted into place and held steady.

Solo was in a luxurious hotel room. Tall French doors stood open on a small marble terrace. Past the balustrade he glimpsed high peaks with bright buildings crowding their shoulders. He saw water - a harbor.

A ferryboat chugged toward the distant, misty mainland. Junks and sampans clogged the water in the nearer distance. From out of sight below the balcony, a city's sing-song cacophony rose.

"Welcome to Hong Kong, Mr. Solo," boomed a familiar voice.

Spinning round, Solo gaped. Beside an open door which he had not noticed stood a Eurasian girl with shoulder-length black hair. Her eyes were pansy-colored. She did not have the typical, slender build of the Oriental woman. She was a few inches taller than Solo himself.

The girl wore a white, shimmering blouse, voluptuously tight black riding trousers and highly polished black boots. Her figure was gorgeous. Her eyes and her pistol weren't.
