‘Were there really such weapons three hundred years ago?’ Artyom was doubtful, but the stalker didn’t reply. They’d seen two or three depictions of the Great Worm on the floor, but there had been no sign of the savages themselves. The first drawing had put the fighters on their guard, and they’d regrouped in such a way that it was easier to defend themselves, but the tension had dissipated after they’d encountered the third drawing.

‘They weren’t jabbering nonsense. Today was a holy day and they stay at the stations and don’t go into the tunnels,’ Ulman noted with relief.

Something else occupied the stalker. By his calculations, the missile unit was very close by. Checking the hand-drawn map every minute, he absently repeated:

‘Somewhere here… Isn’t this it? No, not that corner, but where is the pressurized gate? We ought to be approaching it already…’

Finally, they stopped at a fork: to the left was a dead end with a grille, at the end of which they could see the remains of a pressurized gate, and to the right, as far as the light of the flashlight could reach, there was a straight tunnel.

‘That’s it!’ Melnik determined. ‘We’re there. Everything tallies with the map. There, behind the grille, the tunnel has collapsed like at Park Pobedy. And that must be the passage into which they took Tretyak. So…’ Illuminating the map with his pocket flashlight, he thought aloud, ‘The line goes directly from this fork to the division, and this one, to the Kremlin, we came from there, right.’ Then he climbed behind the grille with Ulman and they wandered around the dead end for about ten minutes, inspecting the walls and ceiling with the flashlight.

‘OK! There’s a passage in the floor this time, a round sort of top, similar to a sewer manhole,’ the returning stalker reported. ‘Everyone, we are there. Take a break.’

As soon as everyone had removed their rucksacks and had sprawled out on the ground, something strange happened to Artyom: despite the awkward position, he fell asleep instantly. Either the fatigue accumulated in the last twenty-four hours had taken its toll or the poison from the paralysing needle was producing some side effects.

Artyom again saw himself, asleep, in the tent at VNDKh. As in his earlier dream, it was gloomy and abandoned at the station. Artyom knew beforehand what would happen to him now. Already accustomed to saying hello to the little girl who was playing, he didn’t ask her about anything, heading instead directly toward the tracks. The distant cries and entreaties for mercy didn’t frighten him. He knew that he was seeing the unwelcome dream again for another reason, one that concealed in the tunnels. He was supposed to uncover the nature of the threat, reconnoitre the situation and report about it to his allies from the south. But as soon as he was shrouded in the darkness of the tunnel, his confidence in himself and in the fact that he knew why he was here and how he had to go on vaporized. He was as frightened as when he went beyond the limits of the station alone for the first time. And exactly as then, it wasn’t the darkness itself nor the rustle of the tunnels that scared him, but the unknown, the inability to foretell what danger the next hundred metres of the line concealed.

Vaguely recalling how he had behaved in previous dreams, he decided not to give in to fear this time, but to go forward, until he met the one who was concealed in the dark, waiting for him.

Someone was coming towards him. Not hurrying, as he was, not walking with his cowardly, slinking short steps, but with a confident heavy tread. Artyom stopped in his tracks, catching his breath. The other one also stopped.

Artyom promised himself that he wouldn’t run this time regardless of what happened. When, judging by the sound, only about three metres of darkness separated them, Artyom’s knees shook, but somehow he found the strength to make one more step. But, feeling a light flutter of the air on his face as someone approached, Artyom couldn’t bear it. Flinging out a hand, he pushed the unseen being away and fled. This time he didn’t stumble and he ran for an intolerably long time, an hour or two, but there was no trace of his home station, there were no stations at all, nothing at all, only an endless, dark tunnel. And this proved to be even more terrible.

‘Hey, that’s enough of a nap, you’ll sleep through the meeting.’ Ulman pushed him on the shoulder.

Artyom roused himself and looked guiltily at the others. It appeared that he had dropped off for only for a few minutes. They were all sitting in a circle. In the centre was Melnik with the map, pointing and explaining.

‘Well,’ he said,’ it’s about twenty kilometres to our destination. If we keep up a good pace and nothing gets in our way, it’s possible to make it in half a day. The military unit is located on the surface, but there is a bunker under it and the tunnel leads to it. However, there’s no time to think about that. We have to split up.’ He looked at Artyom. ‘Are you up? You are returning to the metro, I will appoint Ulman to look after you,’ he said. ‘The others and I are going to the missile division.’

Artyom was on the verge of opening his mouth, intending to protest, but the stalker stopped him with an impatient gesture. Leaning towards the heap of rucksacks, Melnik started to distribute the supplies.

‘You take two protective suits, we have four left, and we don’t know what it will be like there. There’s one radio for you and one for us. Now the instructions. Go to Prospect Mir. They are waiting for you there. I have sent some messengers.’ He looked at his wristwatch. ‘In exactly twelve hours go up to the surface and look for our signal. If everything is OK and we are on the air, we’ll move to the next stage of the operation. Your mission is to find the best way to the Botanical Gardens and then to get up high in order to help us direct and correct the fire. The “Smerch” has a limited destruction area and we don’t know how many missiles are still there. And the gardens aren’t small. Don’t worry,’ he said to Artyom, ‘Ulman will be doing it all, you are there as company. We have use for you too, of course. You know what these dark ones look like.

‘The Ostankino tower is very suitable for guidance. It’s wider in the middle: there was a restaurant there. They served tiny sandwiches with caviar there at prices that were out of sight. But people didn’t go there because of them, but for the view of Moscow. The Botanical Gardens can be seen clearly from there. Try to get to the tower. If you can’t get to the tower, there is a multi-storey building alongside, sort of white, shaped like the letter P, and almost uninhabited. So… This is a map of Moscow for you, and this one is for us. It’s a shambles there around the squares. You simply look and communicate. The rest, follow us. It’s nothing too complex,’ he assured them. ‘Questions?’

‘And if they don’t have a nest there?’ Artyom asked.

‘Well, we can’t do the impossible,’ the stalker slapped his palm on the map. ‘And I have a surprise here for you,’ he added, winking at Artyom.

Reaching into his backpack, Melnik took out a white polyethylene bag with a worn coloured picture on the side. Artyom looked inside and took out the worn passport and the children’s book with the cherished photograph that he had found in the neglected apartment at Kalinskiy inside. Having raced after Oleg, he had left his treasures at Kievskaya, and Melnik had gone to the trouble to collect them and carry them with him all this time. Ulman sitting alongside looked at Artyom with a puzzled look, then at the stalker.

‘Personal things,’ Melnik said, smiling. Artyom wanted to thank him but the stalker had already got up from his seat and was giving orders to the fighters going with him.

Artyom went up to Anton who was absorbed in his own thoughts.
