Chapter 2

      For a dedicated conspiracy buff tainted by more than a whiff of paranoia, nothing could be more alarming than happening to be walking down the street minding your own business when a mysterious black car full of mysterious men suddenly appears from nowhere and pulls up beside you.

      That was exactly what happened to Yuri Petrov one day that summer as he strolled aimlessly about the streets of Moscow. He instantly knew the black Mercedes was an Intelligence Services car. Gripped by panic, he was ready to bolt as the back doors opened and two men, very obviously government agents, climbed out and walked calmly towards him.

      He’d never seen either of them before. But they seemed to recognise him, even with the hair and the beard. Yuri hadn’t been paying so much attention to personal neatness of late.

      ‘Hello, Yuri,’ one of them said.

      The other motioned towards the car’s open door. ‘Let’s go for a drive, shall we?’

      Powerless to refuse, Yuri climbed into the back seat. The two men sat flanking him as the Mercedes sped off. ‘What’s this about?’ he kept repeating. ‘Who are you people? What do you want with me?’

      ‘You’ll find out soon enough. Shut up and enjoy the ride.’

      Twenty minutes later, the Mercedes arrived at a lugubrious government building Yuri had never visited before. They passed through two armed security checkpoints, then whooshed down a ramp into a subterranean car park from where Yuri’s escorts ushered him up several floors in a lift. They stepped out into a corridor that was devoid of any windows or furniture and painted institutional grey. Yuri was so nervous he could hardly control the shaking in his knees as they led him up the corridor. After two years of the Grisha Solokov academy, it seemed to Yuri like the dystopian nightmare coming true.

      Yuri had no idea of what he was about to step into.

      The agents stopped outside an unmarked door. ‘Go in,’ one said to Yuri.

      Yuri did as he was told. He found himself in an office, not a cosy one. The walls and steel filing cabinets and ancient iron radiators and exposed pipes were all painted the same grey as the corridor. There was no carpet and only one window, through whose dusty glass little sunlight was able to penetrate. In front of the window was a large, plain desk, which was completely bare except for a telephone and a slim cardboard folder that lay closed on the desktop.

      Behind the desk sat a man whom Yuri, unlike the men who had brought him here, did in fact recognise. It was his former chief, the man who had first interviewed and employed him in the service, Antonin Bezukhov.

      The chief was a large, heavyset figure in a dark suit. His white hair was buzzed military-short and his face appeared to have been chiselled from a lump of granite. He had to be in his mid-seventies, but if anything he looked more severe and intimidating than Yuri remembered, which was saying something. This was a man rumoured to have personally executed several CIA operatives, back in the glory days of the Cold War. As far as Bezukhov was concerned, the old regime had never ended.

      Bezukhov invited him to sit, and offered him a ghost of a smile. ‘You’re a hard man to find, Yuri. We obviously trained you too well. Where’ve you been hiding yourself these days?’

      Yuri swallowed. ‘Why am I here? What do you want from me?’

      ‘We need you to come back and work for us, one more time,’ said Bezukhov.

      ‘But I’m retired,’ Yuri protested. ‘Out, gone, done with the whole thing. I don’t want anything more to do with any of it.’

      ‘Consider this your heroic comeback,’ the chief said, faintly amused. ‘Come on, Yuri, don’t you know that once you’re in the club, we’d never really let you go? That’s how the game is played, my friend. And now we have another job for you.’

      Yuri could find nothing to say. Bezukhov reached a thick arm across the desk, and a brawny paw of a hand slid the solitary card folder over its surface towards Yuri. ‘Open it.’

      Again, Yuri did as he was told. Inside the card folder was a transparent plastic sleeve, and inside that a single oblong slip of paper. It was heavily aged, as if it had spent many years exposed to the elements. And creased, as though it had been folded up very small throughout that time. Long ago, someone had written four lines of text on the paper, using black ink that had faded somewhat but was still clearly legible. The writing wasn’t in Russian. It used the letters of the English alphabet, though the language wasn’t English either.

      ‘It’s a cipher,’ Yuri said. An old one, too, dating back a good few decades. Seeing it, he couldn’t pretend not to feel a slight stirring of curiosity.

      ‘Good to see you haven’t lost your powers of observation, Agent Petrov.’

      ‘Please don’t call me that.’

      ‘This cipher is the reason I called you in,’ the chief said. ‘You’re going to decode it for us. Just like old times.’

      Yuri studied the cipher more closely. Right away, he could tell it was like no other code he’d come across before. Even back in the pre-cybertechnology dark ages, cryptology had reached a level that was far from crude. ‘It’s not going to be easy.’

      ‘Why do you think we selected you for the task?’ the chief said. ‘Some people haven’t forgotten you used to have a way with these things, back in the old days before these fucking computers took over.’ He spat out the expletive with surprising bitterness.

      As Yuri went on peering at the encrypted text, the chief recomposed himself and explained, ‘The cipher was discovered two weeks ago by a crew of workmen who were demolishing a block of old post-war houses in Novogireyevo District. Coming across an envelope that had been crammed into a crack in a wall, they opened it, saw it was something peculiar and handed it in to the police. Thank God for patriotism, heh?’

      Yuri asked, ‘What was it doing there?’

      Bezukhov smiled, aware that Yuri was being drawn in despite himself. ‘We believe that it was concealed there in February 1957 by a British spy working as part of a network. His cover ID was Pyotr Kozlov, real name Leonard Ingram, a British Army captain recruited to SIS after the war. He and a couple of others were inserted into the Soviet Union that January, as part of a special operation you don’t need to know about. Let’s just say they were stealing secrets. That was before the Anti-Fascist Protection Rampart was put up, and these shits could creep in and out almost as they pleased.’ This was all long, long before Yuri’s time, but he knew the chief was talking about the Berlin Wall.

      Bezukhov levered himself from his chair and went to gaze out of the dusty window. With his back to Yuri he went on, ‘Of course, our boys were onto them the moment they stepped on Russian soil. And we had our suspicions about what they were up to. The cipher is obviously a set of instructions of some kind, which would indicate the nature of the secrets they stole, and their whereabouts. Ingram was on his way to pass those instructions to one of his fellow spies when the KGB jumped the gun and nabbed him too soon. If they’d allowed the meeting to take place, they could have captured both of them together as well as the information they were sharing.’ Bezukhov turned away from the window with a sigh.
