He turned left and I stayed on this side of the boulevard and began looking for cover. This too might be impossible to find in time but it was my main concern. Without Ferris on the scene I could have flushed these tags within minutes because a city is a warren and I am a ferret who knows its way and who knows how close to go and how far: I’ve done it before, a hundred times, and I could have done it again today but there was Ferris and I mustn’t lose him.

I crossed at the intersection and for the first time turned my head to watch for the traffic and saw five of them among the people who were walking from the airport, five or conceivably more because I couldn’t see farther than the second group who were crossing farther down, hurrying before the bus came, one of them slipping and finding his balance again. They were men with coats and hats and gloves and they didn’t look any different from the others in actual appearance: I knew who they were because I’d seen them before, hundreds of them, Russian and Czechoslovak and Polish and French and Italian and Turkish, average and undistinguished men in respectable suits and worn shoes, their movements casual and their faces noncommittal as they worked their daily round like pilot fish. Of course they vary in their temperaments: the subtlest are the French and they’ll hang on whatever you try to do; the Italians will do well until they see a girl and then they’ll go off with her and leave you flat; the Turks will hound you to the ends of the earth and then drive you into the ground; and the Russians will keep their distance but never lose you unless you can pull something totally unexpected, because they are logical and trained to move in straight lines as these were doing now.

A hundred yards after I’d crossed at the intersection and started west along this street the black Moskwicz came past again, but faster this time: it had turned left along the side street parallel to the boulevard and come up and turned left again and found me crossing from the first to the second block and it would now make a series of right turns and come back and look for me two blocks ahead and that was all right, providing it went on doing the same thing and didn’t stop. I liked the pattern as it was, because at this stage I knew where people were and what they were doing.

I suppose London had waited until I was down on Soviet soil and still alive before they’d pulled Ferris out of Furstenfeldbruck and shot him into Moscow with instructions to come down here; it’s relatively easy for the field directors to cross frontiers because they’re never in action and their cover is conservative: most of them double as cultural attache’s or commercial first secretaries as the major embassies and at least half of them are permanently down on the Intourist waiting lists for educational travel-group tours through Russia and the slave states: it’s infinitely easier to get out of a country if you can prove how you came in.

The Moskwicz was turning right.

Ferris was a good fifty yards ahead of me and I lost him sometimes because he was using the environment and doing it well, staying with a chance group of people and finding another before they split up, keeping to the right-hand side of the pavement and pacing his way steadily, sometimes looking at his watch to express purpose and a sense of destination: it was a model performance and it kept my nerves off the limit as we hauled the five men and the Moskwicz westwards along Lenin Prospekt and past the square.

It was now twelve minutes since we’d left the airport and there had been no chance of shaking off these people and I was getting worried because the longer Ferris and I remained in the same street within sight of each other the sooner they’d see the connection and start working on him too. At the moment he was perfectly clear and they weren’t taking the slightest interest in him, any more than they were taking an interest in the other twenty or thirty people moving with us along the Prospekt.

Moskwicz.

Its number was half covered in slush but there was a small triangular dent on the rear wing and that was good enough. It went past at the same pace as the traffic; it wasn’t observing me: it was standing by in case I decided to find a taxi or get on a bus. If that happened they -

Ferris had gone.

I kept walking.

Clothing store. Warehouse. Three unidentified offices in a row. Bus station.

The Inter-Kazakh State Lines, a vast roofed area with water puddling below the mud flaps of three long-distance buses that had just come in, one of them still discharging passengers in the blue-grey artificial light. No sign of Ferris: he was too good for that.

I walked steadily for three blocks and checked everything twice: every doorway, every parked vehicle, every wall, basement and side entrance to every building, and drew blank all the time. I didn’t want to alter the basic pattern but the time factor was now taking over: Ferris couldn’t wait for me indefinitely at the bus station and I had to get back there and locate him as soon as I could. His own timing might be critical: he was in this city to rendezvous with the executive but there could be other things he had to do here, involving Chechevitsin or a mobile Bureau cell or Kirinski himself through any one of a dozen Central Asian channels. I didn’t know the background and I wasn’t going to assume anything at this stage. The one thing I had to do was to get back to that bus station and if I couldn’t find a chance then I’d have to make one and risk blowing Slingshot.

This was normal. In any given mission you’re operating right on the very edge.

Three doorways, two deep, one shallow. A line of Red Army vehicles, one of them an armoured car with a gunner perched on the roof struggling with the antenna. I stopped and called up to him.

“Comrade! Is this the way to Central Station?”

He looked down, his eyes dark with frustration: it looked as if they’d hit the antenna on something hard enough to bend it at the base, and his hands were too cold to straighten it. “Where?”

“The station. The main station.”

“Straight on.”

I nodded and walked away, checking my watch and looking around for a taxi. The station was three miles from here and the first of the street lights were coming on and it was logical for me to hurry. They knew I’d abandoned the Trabant because of me windscreen and the railway station was a plausible destination and in any case they wouldn’t question it because they would go wherever I took them.

The nearest tag would now be questioning the soldier: what had I asked him, so forth. I’d done it to reassure them, and if I’d only succeeded by one degree my chances were by that one degree improved.

Doors, windows, railings, a parked truck, blank, drawing blank.

Three blocks and I was walking through the night, with the streetlamps taking over the evening sky. Three taxis had gone past and I’d tried to stop them because sharing was an established custom but they were obviously full.

Moskwicz.

This time it turned at one of the prescribed U-junctions and went back the other way, a blurred face checking me before it turned right and began working its way back to Lenin Prospekt.

One of the tags was quite close behind me: I’d seen his reflection twice in the past few minutes. The light was less reliable now and they were tightening their distances. I was getting a better look at them now because whenever I heard a car I turned round to see if it was a taxi and they knew what I was doing because I’d shown them.

Two more went past but I got the third and it was empty.

“Where to?”

“Central Station.”

One of them had broken into a short run but the Moskwicz had made its circuit and come back into the Prospekt and he left it for them to take up the tag in its mobile phase and we moved off with the black saloon a reasonable distance behind and with one small Syrena between us.
