She was more right than she knew.

Raisa touched his arm.

-Are you OK?

She'd asked him what was in the letter. He'd considered lying and telling her it contained information about his familypersonal details that he'd forgotten. But she'd have known he was lying. So, instead, he'd told her the truth that he'd destroyed the letter, ripped it into a hundred pieces, thrown it out of the window. He didn't want to read it. His parents could rest easily believing that they'd unburdened themselves. To his relief she hadn't questioned his decision and hadn't mentioned it since.

Using their hands they dug away at the cover of leaves and loose soil, unearthing their belongings. They took off their city clothes, intending to change back into the trail gear they'd set out ina necessary part of their cover. Undressed, alone, they paused, naked, staring at each other. Perhaps it was the danger, perhaps it was opportunistic, but Leo wanted her. Uncertain about her feelings for him, he did nothing, waiting, afraid to make the first move, as though they'd never had s.e.x before, as though this was their first time with both of them unsure of the boundaries, unsure what was acceptable and what wasn't. She reached out, touching his hand. That was enough. He pulled her towards him, kissing her. They'd murdered together, deceived together, plotted and planned and lied together. They were criminals, the two of them, them against the world. It was time to consummate this new relationship. If only they could stay here, live here in this exact moment, hidden in the forests, enjoying these feelings forever.

They rejoined the forest trail, walking into town. Arriving at Basarov's they entered the main room. Leo was holding his breath, expecting hands to grab his shoulders. But there was no one here, no agents and no officers. They were safe, at least for another day. Basarov was in the kitchen and didn't even turn round when he heard them arrive.

Upstairs, they unlocked their room. A note had been pushed under the door. Leo put his bags down on the bed. He picked up the note. It was from Nesterov, dated today.

Leo, if you're back as planned, meet me tonight in my office at nine. Come alone. Bring all the doc.u.ments relating to the matter we've been discussing. Leo, it's very important that you're not late.

Leo checked his watch. He had half an hour.

Same Day Even back in the militia headquarters, Leo was taking no chances. He'd hidden the papers in official doc.u.ments. The blinds to Nesterov's office were drawn shut and it was impossible to see in. He checked his watch: he was late, two minutes late. Unable to see how that would matter particularly, he knocked on the door. Almost as soon as he did the door was opened, as though Nesterov had been waiting behind it. Leo was ushered in with a sudden, inexplicable urgency, the door shut behind him.

Nesterov was moving with an uncharacteristic impatience. His desk was covered with doc.u.ments from the case file. He took hold of Leo by the shoulders and spoke in a hushed, hurried voice.

-Listen very carefully and don't interrupt. I was arrested in Rostov. I was forced to confess. I had no choice. They had my family. I told them everything. I thought I might be able to persuade them to help, persuade them that they should to elevate our case to an official level. They reported it back to Moscow. They've accused us of anti-Soviet agitation. They think this is a personal vendetta you have against the State, an act of revenge. They dismissed our findings as an elaborate piece of Western propaganda: they're certain that you and your wife are working as spies. They offered me a choice. They're prepared to leave my family alone if I give them you and all the information we've collected.

Leo's world fell away. Even though he'd known danger was close he hadn't expected it to cut across his path just yet.

-When?

-Right now. The building's surrounded. Agents will enter this room in fifteen minutes, arresting you in this office and collecting every piece of evidence we've ama.s.sed. I'm to spend these minutes finding out all the information you discovered in Moscow.

Leo stepped back, looking at his watch. It was five past nine.

-Leo, you have to listen to me. There's a way for you to escape. But for this to work don't interrupt, don't ask any questions. I've come up with a plan. You're going to hit me with my gun, knocking me unconscious. You're then going to leave this office, go down one flight of stairs and hide in the offices to the right of the stairway. Leo, are you listening? You need to concentrate. The doors are unlocked. Go into them, don't turn on the lights and lock the doors behind you.

But Leo wasn't listeningall he could think about was.

-Raisa?

-She's being arrested as we speak. I'm sorry but there's nothing you can do about her. You need to concentrate, Leo, or this is over.

-This is over. This was over the moment you told them everything.

-They had everything, Leo. They had my work. They had my file. What was I supposed to do? Let them kill my family? They still would've arrested you. Leo, you can get angry with me, or you can escape.

Leo shook free of Nesterov's grip, pacing the office, his mind trying to catch up. Raisa had been arrested. They'd both known this moment would come but had understood it only as a concept, an idea. They hadn't understood what it would mean. The prospect of never seeing her again made it difficult to breathe. Their relationship, their relationship reborn, consummated barely two hours ago in the forest, was over.

-Leo!

What would she want? She wouldn't want him to get sentimental. She'd want him to succeed, to escape, to listen.

-Leo!

-All right, what's your plan?

Nesterov continued, recapping the first part: -You're going to hit me with my gun, knocking me unconscious. You're then going to leave this office, go down one flight of stairs and hide in the offices to the right of the stairway. Hide in those offices; wait until the agents enter the building. They'll come up to this floor, pa.s.sing you by. Once they've gone past, you descend to the ground floor, exiting through one of the windows at the back. There's a car parked there. Here are the keys, which you will have stolen from me. You have to leave town, don't look for anyone or stop for anything, just drive. You will have a small advantage. They'll believe that you're on foot, somewhere in the town. By the time they realize you've taken a car, you should be free.

-Free to do what?

-To solve these crimes.

-My trip to Moscow was a washout. The eyewitness refused to talk. I still don't have any more of an idea of who this man is.

That took Nesterov by surprise.

-Leo, you can do this, I know it. I believe in you. You need to head to Rostov-on-Don. That's the centre of these crimes. I'm convinced that's where your efforts must be focused. There are theories about who is killing these children. One involves a group of former n.a.z.i- Leo interrupted.

-No, it's the work of an individual, acting alone. He has a job. He appears normal. If you're sure the concentration of murders is Rostov then it's likely he lives and works there. His job is the connection between all these locations. His job means that he travels: he kills as he travels. If we can work out his job, then we have the man.

Leo checked his watch. There were only minutes left before he'd have to leave. Nesterov put his fingers on the two towns in question.

-What is the connection between Rostov and Voualsk? There have been no murders east of this town. At least that we know of. That suggests that this is the end point, this is his destination.

Leo agreed.

-Voualsk has the car a.s.sembly plant. There are no other significant industries here other than the lumber mills. But there are lots of factories in Rostov.

Nesterov knew both locations better than Leo.

-The car factory and the Rostelmash share close ties.

-What is the Rostelmash?

-A tractor factory, enormous, the biggest in the USSR.

-Do they share components?

-The tyres for the GAZ-20 come from there while engine components are shipped south in exchange.

Could that be the connection? The murders followed the train lines up from the south and across into the west, point to point. Running with this theory, Leo remarked.

-If the car plant sends deliveries to the Rostelmash factory then that factory must employ a tolkach tolkach. Someone travels here to make sure the car plant fulfils its quota obligations.

-There have only been two child-murders here and they were recent. The factories have been working together for some time.

-The murders in the north of the country have been the most recent. That means he's just got this job. Or that he's only just been posted along this route. We need the employment records at Rostelmash. If we're right, by cross-referencing those records with the locations of these murders we'll have the man.

They were close. If they weren't being hunted, if they had the freedom to act at their leisure, they could've discovered the killer's name by the end of the week. But they didn't have a week, or the support of the State. They had four minutes. It was eleven past nine. Leo had to leave. He took one doc.u.mentthe list of murders, compiled with dates and locations. That was all he needed. Having folded it into his pocket he moved to the door. Nesterov stopped him. He was holding his gun. Leo took hold of the weapon, delaying for a moment. Nesterov saw this hesitation and remarked: -Or my family will die.

Leo struck him across the side of his head, splitting the skin and sending him to his knees. Still conscious, he looked up.

-Good luck, now hit me properly.

Leo raised the gun. Nesterov closed his eyes.

Hurrying into the corridor, Leo reached the stairs only to realize he'd forgotten the car keys. They were on the table. He turned around, ran back down the corridor into the office, stepping over Nesterov, grabbing the keys. He was latenine fifteen, agents were entering the building. Leo was still in the office, exactly where they wanted him. He ran out, down the corridor, down the stairs. He could hear footsteps coming up towards him. Reaching the third floor he darted to the right, grabbing hold of the nearest office door. It was unlocked, as Nesterov had promised. He entered, locking the door behind him just as the agents ran up the stairs.

Leo waited in the gloom. All the blinds had been closed so that no one from outside could see in. He could hear the clump of footsteps. There were at least four agents on this stairway. He was tempted to remain in this room, behind this locked door, in temporary safety. The windows opened out onto the main square. He glanced out. There was a ring of men outside the main entrance. He pulled away from the window. He had to reach the ground floor and the back. He unlocked the door, peering out. The corridor was empty. Shutting the door behind him he moved to the stairway. He could hear an agent's voice below him. Leo ran to the next stairway. He couldn't see or hear anyone. As soon as he began running, shouting broke out on the top floor: they'd found Nesterov.

A second wave of agents entered the building, alerted by the calls of their colleagues. It was too much of a risk going down another flight of steps, and abandoning Nesterov's plan, Leo remained on the first floor. He only had moments of confusion to exploit before the men organized themselves into search teams. Unable to reach the ground floor, he ran along the corridor, entering the toilet, a room facing out onto the back of the building. He opened the window. The window was high up, narrow, barely wide enough to squeeze through. The only way he'd fit was if he clambered head first. Checking outside, he couldn't see any officers. He was maybe five metres above the ground. He pulled his body through the window, hanging above the ground, supported by his feet. There was nothing to grab onto. He'd have to let himself fall, protecting his head with his hands.

He hit the ground with his palms, his wrists snapping back. He heard a shout, looked up. An agent was at the top-floor window. Leo had been spotted. Ignoring the pain in his wrists, he stood up, running towards the side street where the car was meant to be parked. Shots rang out. Puffs of brick dust exploded to the side of his head. He dropped down, crouching, still running. More shots rang out, pinging off the street. He turned the corner out of the line of fire.

The car was there, parked, ready. He clambered in, slotting the key in the ignition. The engine spluttered and died. He tried again. It wouldn't start. He tried againplease-this time it started. Putting the car into gear, he pulled out, accelerating, careful not to let the tyres screech. It was crucial that the agents following didn't see the car. He'd be one of the few cars on the streets. Since it was a militia vehicle, hopefully any officers who saw it would presume he was on their side whilst they continued their search on foot.

There was no traffic. Leo was driving too fast, too ragged, heading out of the city. Nesterov was wrong: he couldn't drive all the way to Rostov. For a start it was several hundred kilometres, he didn't have anywhere near enough petrol and he had no way of getting any more. More importantly, once they figured out that he'd taken a car they'd shut down all the roads. He had to get as far away as he could then dump the car, conceal it and slip into the countryside, before boarding a train. As long as they didn't find the abandoned car his chances were much better without it.

He accelerated onto the only major connecting road which led in and out of the town, travelling west. He checked the rear-view mirror. If they were going to organize a comprehensive search of the nearby buildings, believing him to be on foot, then he might have at least an hour or so head start. He increased his speed, reaching the car's top speed of eighty kilometres per hour.

Up ahead there were men standing on the road cl.u.s.tered around a parked car: a militia car. It was a roadblock. They'd taken no chances. If the road west was blocked so was the road heading east. They'd closed down the entire town. His only hope now lay in punching through the roadblock. He'd pick up enough speed, smash into the car positioned across the road. The car would be knocked aside. He'd have to control the impact. With their car damaged, they wouldn't be able to pursue him immediately. It was desperate, shortening his advantage to a matter of minutes.

The agents up ahead began firing. Bullets. .h.i.t the front of the car, sparking against the metal. A bullet punctured the windscreen. Leo lowered himself behind the steering wheel, no longer able to see the road. The car was in position: he just had to hold steady. Bullets continued smashing through the windscreen. Fragments of gla.s.s showered down. He was still on coursebraced for the collision.

The car lurched down and to the side. Sitting back up in the seat, Leo tried to maintain control but the car veered left, pulling away from him. The tyres had been shot out. There was nothing he could do. The car flipped onto its side, the window smashing. He was thrown against the door, millimetres from the road, skidding, sparks flaring up. The front smashed into the other car, spinning Leo's car around. It rolled onto the roof, running off the road into the verge. Leo was tossed from the door to the roof where he lay huddled as the car finally came to a stop.

Leo opened his eyes. He wasn't sure if he could move and he couldn't muster the strength to find out. He was staring up at the night sky. His thoughts moved slowly. He was no longer in the car. Someone must have dragged him out. A face appeared above him, blocking the stars, looking down at him. Concentrating, Leo focused on the man's face.

It was Vasili.

Rostov-on-Don Same Day Aron had been under the impression that a job in the militia might be exciting or at least more exciting than working on a kolkhoz kolkhoz. He'd always known it didn't pay very well but the upside was that compet.i.tion wasn't fierce. When it came to looking for work he'd never been a strong candidate. There was nothing wrong with him. In fact, he'd done well at school. However, he'd been born with a deformed deformed upper lip. That's what the doctor had told himit was upper lip. That's what the doctor had told himit was deformed deformed and there was nothing he could do. It looked as though a portion of his upper lip had been cut away and the remaining bits st.i.tched together so that the lip went up in the middle, revealing a portion of his front teeth. The overall result was a permanent sneer. Although this made no difference to his ability to work it certainly made a difference to his ability to get a job. The militia had seemed like the perfect solution, they were hungry for applicants. They'd bully him, make comments behind his backhe was used to that. He'd put up with it all just as long as he got to use his brain. and there was nothing he could do.

Yet here he was, in the middle of the night, sitting in the bushes, getting bitten by bugs, watching a bus shelter for signs of

unusual activity.

Aron hadn't been told why he was sitting here or what unusual activity unusual activity might possibly mean. As one of the youngest members of the department, only twenty years old, he wondered if this was some kind of initiation rituala test of loyalty, to see if he could follow orders. Obedience was valued more than anything else. might possibly mean. As one of the youngest members of the department, only twenty years old, he wondered if this was some kind of initiation rituala test of loyalty, to see if he could follow orders. Obedience was valued more than anything else.

So far the only person around was a girl at the nearby bus stop. She was young, maybe fourteen or fifteen, but she was trying to look older. She seemed drunk. Her shirt was unb.u.t.toned. He watched her straighten her skirt and play with her hair. What was she doing at the bus stop? There were no buses until the morning.

A man approached. He was tall, wearing a hat and long coat. His gla.s.ses had lenses as thick as gla.s.s bottoms. Carrying a smart case, he stood by the timetable, reading it with his finger. As though the girl was some kind of scantily clad spider, waiting in the corner she immediately got up, moving towards him. He continued reading the timetable as the girl circled him, touching his case, his hand, his jacket. The man seemed to ignore these advances until finally he looked away from the timetable, studying the girl. They spoke. Aron couldn't hear what they were saying. The girl disagreed with something, shaking her head. Then she shrugged. They were in agreement. The man turned around and seemed to stare straight at Aron, looking right at the undergrowth beside the shelter. Had the man seen him? It didn't seem likelythey were in light, he was in shadow. Both the man and girl began walking towards him, straight towards the place where he was hiding.

Aron was confused, checking his positionhe was completely hidden. They couldn't have seen him. Even if they had, why were they walking towards him? They were only metres away. He could hear them talking. He waited, crouched into the undergrowth, only to find that they'd walked straight past him, heading into the trees.

Aron stood up.

-Stop!

The man froze, his shoulders hunched up. He turned around. Aron did his best to sound authoritative.

-What are you two doing?

The girl, who didn't seem at all afraid or concerned, answered: -We were going for a walk. What happened to your lip? It's really ugly.

Aron flushed with embarra.s.sment. The girl was staring at it with obvious disgust. He paused for a moment, composing himself.

-You were going to have s.e.x. In a public place; you're a prost.i.tute.

-No, we were going for a walk.

The man added, his voice pathetic, barely audible: -No one has done anything wrong. We were just having a conversation.

-Let me see your papers.

The man stepped forward, fumbling for his papers in his jacket. The girl hung back, nonchalant: no doubt she'd been stopped before. She didn't seem fazed. He checked the man's papers. The man was called Andrei. The papers were in order.

-Open your case.

Andrei hesitated, sweating profusely. He'd been caught. He'd never imagined this would happen: he'd never imagined his plan would fail. He lifted the case, opening the buckle. The young officer peered in, his hand tentatively searching through. Andrei stared down at his shoes, waiting. When he looked up the officer was holding his knife, a long knife with a serrated blade. Andrei felt close to tears.

-Why do you carry this?

-I travel a lot. Often I eat on trains. I use the knife to cut salami. Cheap, tough salami but my wife refuses to buy any other kind.

Andrei did use the knife for lunch and dinner. The officer found half a stick of salami. It was cheap and tough. The edge was rough. It had been cut by the same knife.

Aron lifted out a gla.s.s jar with a sealed top. The jar was clean and empty.
