When Tung spoke, it seemed to me that he was using precisely similar cadences and intervals as in the original Russian, and I admired his skill; he used names and speechcode, as he'd heard me do, but when his totally dissimilar message came it carried a brute shock.

"The American Charge d'Affaires has just been ambushed and shot dead in Pekin. You must find my son. The next action is scheduled for noon tomorrow."

I pushed down the transmit lever, sickened, and gave the message to Ferris. There were people above Croder in London, all the way up to the Prime Minister, though he could short-circuit them and reach her direct if he had to. And by now she'd be asking questions as the slaughter went on.

The British Foreign Secretary, the American Ambassador, the passengers on board that airliner and now the American Charge d'Affaires. Have you replaced the agent in the field?

No, Prime Minister. He's close to the opposition now.

How close?

Very close. Within reach of an act of sanction.

A pause on the line while she considered, watching the rain on the window. Then what is holding him up? The tone severe as she demanded of Croder, and Ferris, and the agent in the field to do what they were paid to do, and to do it now.

There are difficulties, ma'am. The agent's position is hazardous in the extreme.

He's alone?

Yes.

Can't you invoke assistance from others? From NATO forces in the area, for instance?

While the rain ran down the window and the red buses swayed through the streets, and the pigeons huddled along the parapets, as Big Ben chimed the hour, and the agent "in the area" sat in his sweat at the radio console feeling as Impotent and as incompetent as that clear and admonishing voice declared that he was.

"Message understood."

Ferris.

We waited. In a moment Sinitsin said: "In addition to the assistance of the Japanese Red Army team, there will be — " Then he broke off as the other radio opened up with a signal, and our heads turned to watch the illuminated panel. The sender was speaking in Russian.

"Zero-one-nine. Zero-one-nine to Action 5."

Major Alyev moved quickly to the transceiver and switched to transmit. "Action 5 to Zero-one-nine, receiving you." Sinitsin took three precise paces and stood next to his aide. There were now only Captain Samoteykin and Yang behind me, but they were both armed and I knew that Yang had his finger inside the trigger-guard of the machine gun, and I was already feeling that sinister vibration in the air as Tung Kuo-feng sensed my thoughts.

"Zero-one-nine to Action 5. Further to our transmission of 14:16 hours, the developing opposition activities in the vicinity of Sinch'on-ni necessitate the removal of Tung Chuan to a more secure environment. Acknowledge."

I looked away from the transceiver but went on listening.

This was Moscow.

Alyev touched the transmit lever. "Action 5 acknowledging.

This is a tough one, Ferris had said a few minutes ago on the other radio; but London had launched a massive intelligence search in response to my signal of last night, and local agents had been sensitised to the area where Tung Chuan was being held, and the KGB unit had felt the trembling of the web. At some time while I was in my cell playing with bricks there had been earlier transmissions, alerting Sinitsin, who in turn had reported to Moscow.

"Zero-one-nine to Action 5. Tung Chuan and our party will board Cathay Pacific Flight 584 departing Kimpo Airport, Seoul, 02:18 tomorrow, destination Pyongyang, North Korea. Our party will signal you on arrival. Acknowledge and repeat."

Major Alyev responded.

I sat picking at the grime that had got under my nails since I'd dropped out of the sky two nights ago. I was listening to the death knell of Jade One and there was nothing I could do about it. When Alyev completed the exchange and switched to automatic receive he was going to put the light out over the board in London.

Croder had been getting warm: too warm. They had all lent their weight to the concerted effort to find Tung Chuan: the sleepers and the agents-in-place throughout South-east Asia, the Asian Signals Coordinate, the Soviet Department V Operations Monitor Section, Dossier File (Asia), Intelligence Support Stations (South Korea) and Active Signals Search. The mobile direction-finding units had deployed their equipment into the areas indicated by reports and information coming in from the departments and support stations in London and Asian theatre, and had gradually closed in on the region of Sinch'on-ni. In another few hours they would have made a hit, and signalled Ferris; London would have ordered a para-military operation to release Tung Chuan, and soon afterwards we would have heard the thunder of a fighter aircraft passing through the night sky low above the monastery here, and Tung Kuo-feng would have turned to Colonel Sinitsin and said: I shall do no more for you.

Mission completed, objective achieved, so forth.

But not now.

"Zero-one-nine to Action 5. You will remain open to receive."

The KGB major acknowledged and left the receiver circuit open.

I had enough time. It would only need ten seconds to hit my own transmit lever and tell Ferris: Tung Chuan is being flown from Seoul to Pyongyang at 02:18 tomorrow, Cathay Pacific Flight 584. Get him. But I hadn't been told to start transmitting again and the moment Sinitsin heard me he'd be auspicious and if he didn't stop me before I'd finished the signal he'd pick up "Tung Chuan", «Seoul», "Pyongyang" and "Cathay Pacific" and would realise I understood Russian and was passing on the message from Moscow. He would then do two things: he would have me taken outside and shot and he would signal Moscow and tell them the plans would have to be changed. And Ferris could send in a whole battalion of NATO troops to pick up Tung Chuan at the airport tomorrow morning, and draw blank.

There was tension in the room again.

"If they move him to Pyongyang," Captain Samoteykin began, but Sinitsin cut him short.

"Say nothing now."

Professional caution: he wasn't trusting the Korean interpreter, the only non-Russian here — as far as he knew — who could speak the language.

Tension from Tung Kuo-feng, too. He must have picked up the same names from the Russian, expecially "Tung Chuan", and probably realised his son was being taken from Seoul to Pyongyang; he didn't know the flight number or the time of departure, but the move was probably imminent and he'd heard the name of the airline; if he signalled his Triad they would move in on Kimpo Airport and wait for Tung Chuan to arrive and try to get him out of the hands of his KGB guards.

But he couldn't transmit without instructions, any more than I could; if he made an attempt, the interpreter would read his Chinese and warn Sinitsin before he'd finished transmitting.

Some of the tension in the room was my own. While Tung was learning that his son was to be moved out of our reach and into North Korea, I was learning the most bitter lesson of the executive in the field: that he can come critically close to bringing off a mission and still have to see it snatched away from him without a chance in hell of holding on.

I wanted only ten seconds with my director on this radio, but I couldn't have it, and the only signal I could send that would make any sense would be: Ferris, we're finished.
