'Can I think myself off this ship?'

'The brain is a wonderful thing.' She put the knife aside.

'I wish the brain were a ticket. How long have I been asleep?'

'One hour, maybe two. Tell me about Zina.' She wiped the sweat from his brow and eased him back on to his pillow. His hand was still cramped from holding the knife, and she began massaging the fingers. 'Even when you're wrong, I like to hear how you think.'

'Really?'

'It's like listening to someone play the piano. Why did she come on the Polar Star, to smuggle those stones?'

'No, they were too cheap. Natasha, I want the knife.'

'But just for herself the stones might have been enough.'

'A Soviet criminal rarely operates alone. You don't find a Soviet criminal alone in the dock. There are five, ten, twenty in the dock at a time.'

'If it wasn't an accident, and not for one second am I saying that it was anything but, maybe it was a crime of passion.'

'It was too clean a murder. And planned. For her blood to pool the way it did she must have been stowed for at least half a day before she went into the water. That means moving her to hide her, then moving her again to throw her overboard. We were fishing harder then, people were on deck.'

Arkady stopped for breath. A therapeutic massage was not easy to distinguish from torture.

'Go on,' Natasha said.

'Zina fraternized with Americans, which she only could have done with the permission of Volovoi. She informed for Volovoi. There wouldn't be any reprimand from the galley staff because they were told to let her roam, and she probably kept Olimpiada happy by feeding her chocolates and brandy. But why did Zina always go to the stern deck when the Eagle delivered fish? And only when the Eagle delivered fish, not any other boat? To wave to a man she might dance with one night out of every two or three months? Is Slava's band that good? Maybe the question should be asked the other way. What were the Americans looking for when they delivered fish?'

Arkady didn't mention the possibility that there was an intelligence station on the Polar Star. On the tape the lieutenant invited Zina into the station when fish were coming on board. Did the station only operate between incoming nets? Was it a matter of nets or Americans?

'Anyway,' he said, 'Americans, various lovers, Volovoi - a lot of people used Zina or were used by her. We don't have to be brilliant, we just have to see the pattern.'

He remembered her voice on the tape: 'He thinks he tells me what to do. A second thinks he tells me what to do.' Arkady counted the 'He's. Four significant men, one of whom even she knew was a killer.

'What people?' Natasha asked.

'An officer, for one. He could be compromised.'

'Which?' She was alarmed.

He shook his head. His hands were pink, as if they'd come out of boiling water. They felt that way.

'What do you think?' he asked her.

'About First Mate Volovoi, I don't agree. About the Americans, they must answer for themselves. About Olimpiada and the chocolates, you may be right.'

When he awoke again Natasha had returned with a giant samovar, a silver urn with a spigot for a nose and cheeks shining with good-natured heat. While they took tea, each drinking from a steaming glass, Natasha sawed a round loaf of bread.

'My mother drove trucks;. Remember how we built trucks then, when the factories fulfilled their plan according to gross weight? Each truck weighed twice as much as trucks anywhere else in the world. Try to steer one of those in the snow.

'The route was across a frozen lake. My mother was a shockworker of Communist Labour; she was always in the first truck. She was popular. She had a photo album and she showed me a picture of my father. He drove too. Maybe you wouldn't think it, but he looked surprisingly intellectual. He read anything, could argue with anybody. Wore glasses. His hair was light, but actually he looked a little like you. She said he was too romantic was his problem; he was always in trouble with the bosses. They were going to be married, but in the spring, in the thaw, his truck went through the ice.

'I grew up around dams. I always loved them. There's nothing on earth as beautiful and beneficial to mankind. Other students were interested in special institutes, but I got out of school as fast as I could and up on a scaffold with a mixer. A woman can mix cement as well as any man. The most exciting time is working at night under lights powered by the last dam you helped to build. Then you know you're someone. A lot of the men, though, are drifters because they make so much money. That's their dilemma. They make so much money that they have to drink it up or spend it going to the Black Sea or on the first girl like Zina. They don't make homes. It's not their fault. It's the site directors who are shameless, who offer anything to get their project finished first. Naturally the men say, why stay in one place when you can sell yourself for more money somewhere else? That's Siberia today.'

The net slid up the stern ramp into a circle of sodium lamps, rose on boom cables and swayed as if alive, sea water weeping from chafing hair and flowing over the deck in shallow waves. Forty tons or fifty tons of fish, maybe more! half a night's quota in one tow. Crabs danced over wooden planks. Taut cables moaned from the weight as the trawlmaster flashed his scalpel and on the run sliced the belly of the bag from one end to the other. The whole net seemed to split open at once, flooding the deck up to the gunwale rail and boat deck stairs in a rich, live, twisting mass of slime eels, milky blue in the light . . .

Arkady awoke with a start, heaved off his blankets, pulled on his boots, found his knife and fought the door to get out of his cabin. It wasn't just a claustrophobia but a sense of being buried dive; leaving the bed didn't help if he was still below steel decks.

Outside the lights were smothered in an underlit night fog, no worse than the smoke of a fire. He'd slept through the entire afternoon. It was now a day and a half since he'd first been introduced to Zina Patiashvili's dead body, and he was feeling rather that way himself. And he had less than twelve hours before he was supposed to uncover some startling revelation that would resolve to everyone's satisfaction the mysterious death of Zina Patiashvili and allow the ship's crew to go into port. He stumbled against the rail, inching away from the trawl deck towards the bow. The catcherboats had disappeared, so there were neither stars or other lights to lead the eye away from the dull glow of the Polar Star's lamps.

The deck was empty, suggesting that it was dinner time. Everyone was falling into a single schedule now that the factory ship had stopped taking fish and was steaming to port. He hooked an elbow over the rail for support. This was not going to be the usual brisk perambulation around the deck. It would be a stroll with ample time to think about drowning, about fear that wrapped like a wet shroud around his heart. He marked his progress by the machine shop. The bridgehouse was a goal far in the distance, dissolving in the mist.

'The poetry lover.'

Arkady turned towards Susan's voice. He hadn't heard her approach.

'Taking a break?' she asked.

'I like the sea air.'

'You look it.' She leaned on the rail next to him, pushed her hood back and lit a cigarette, then held the match up to his eyes. 'Christ!'

'Still pink?'

'What happened to you?'

His muscles were still cramping, going from numb to hot to numb again. As casually as possible he gripped the handrail. He would have walked away if he could have trusted his legs to make a dignified exit. 'I was just trying to See in New Ways. It was a strain.'

'Oh, I get it,' Susan said as she glanced around the deck. 'This is the scene of the accident; that's why you're here. It's still an accident, isn't it?'

'Of the unexplained sort,' Arkady granted.

'I'm sure you'll come up with the right explanation. They wouldn't have picked you unless they knew you would.'

'Thank you for your confidence.' He felt his knees sag treacherously. If she disdained him so much, why didn't she go?

'I wondered,' she said.

'Now you're wondering?'

'Well, you questioned the fishermen on the catcher-boats. Weren't they all off the Polar Star before anything happened to Zina?'

'It appears so.' She wants to know, he thought.

'You're almost for real, aren't you? I hear Slava is running everywhere looking for a suicide note, but you stagger around as if you actually want to know what happened. Why?'

'That's a mystery to us all.' Although his mouth tasted like a gas tank, he felt the urge for a smoke. He patted his pockets.

'Here.' Susan put her cigarette between his lips and then pulled back from the rail. At first he thought that it was from him; then he saw that the Eagle had come alongside out of the fog. As the trawler edged nearer, he could make out the form of George Morgan on the darkened bridge. In the lights of the deck, two fishermen in slickers were tying torn mesh and garbage to dump at sea. Arkady recognized Coletti's sullen glare and Mike's open grin. The Aleut's picture was the same as in Zina's photo: innocent and without shading.

The deck around the men was wet and littered with flatfish and crabs, and though the trawler was pitching more than the Polar Star, the Americans seemed rooted where they stood in forward-leaning, lock-kneed stances. Between the two boats was a shifting screen of birds that materialized out of habit. Perhaps a hundred birds hovered on outstretched wings: black-capped terns with swallow tails, masked petrels and milk-white gulls seesawing overhead. They looked as if someone had emptied a basket of papers off the ship and the pages had flown and kept pace. The slightest dip of one bird created a ripple of adjustments, so the flock shimmered and squawked.

Mike waved again and it took Arkady a moment to realize that a third person had joined him and Susan at the rail. Natasha spoke into Arkady's ear. 'I found someone who wants to talk to you. I went to your cabin and you were gone. Why did you get out of bed?'

As he started to describe the benefits of fresh air, Arkady began to cough, which set off a chill that doubled him over. There seemed to be frozen bits inside of him which, as they melted, spread currents of debilitating cold.

With one eye on Susan, Natasha went on talking as if they were taking tea at the rail. 'Now it's time for my lecture. Afterwards, we'll go meet my friend.'

'Your lecture?' Susan made it clear she was trying not to smile.

'I am the ship's representative of the All-Union Knowledge Society.'

'How could I have forgotten?' Susan asked.

It would have been less cruel for her to laugh out loud, because Natasha only had the sense that she was being mocked, the way a woman whose slip shows only at the rear is vaguely aware that she is the subject of humour without knowing why. Out of sheer nervousness she took the cigarette from Arkady's mouth. 'In your condition the last thing you need is this.' She turned to Susan. 'This is the most disgusting habit of Soviet men. Smoking is man's most unnatural act.'

She snapped the cigarette at the birds. A gull tipped its wings, caught it, then dropped it. A petrel slid forward, caught the tumbling cigarette, ate half and rejected the rest. The filter landed in the water, where it was studied by a tern.

'They must be Russian birds,' Susan said.

An idea struck Arkady while he coughed. Susan was wearing a fishing jacket and Natasha was wearing a fishing jacket; it was about all the two of them had in common. Where was Zina's fishing jacket? He hadn't thought about it before because no one took a jacket to the dance, and during intermissions when people went on deck they could stand a few minutes of sub-Arctic air. Soviet women especially wouldn't bother with any jacket that might encumber an embrace. In their stolid frames were souls so romantic that they lifted like doves on the slightest breeze.

As Arkady finished his last rasp and straightened up, Susan lit another cigarette and kept it for herself.

'Renko, are you the investigator or the victim?'

'He knows what he's doing,' Natasha said.

'That's why he looks like the shark's lunch?'

'He has a system.'

What is it? Arkady wondered.

Morgan's voice came from the radio in Susan's pocket: 'Ask Renko what happened to Zina. We all want to know.'

On the deck of the Eagle, Mike waved again and gestured to Natasha as if inviting her down for a visit. Her cheeks reddened, but she gave the fisherman her shoulder to indicate that fraternization was an item strictly in her past. 'We have to go to the lecture,' she said firmly.

'They want to know what happened to Zina,' Susan said.

Unsure of his legs, Arkady tested them with a casual shuffle.

'What do you want me to tell them?' Susan asked.

'Tell them,' Arkady stalled. 'Tell them they still know more than I do.'

Chapter Fifteen.

The inspirational lecture on scientific atheism given in the cafeteria by Natasha Chaikovskaya, corresponding member of the All-Union Knowledge Society, was well attended by the off-duty crew because Volovoi stood at the back, his raw face scanning not only the presence but the enthusiasm of the audience. Skiba and Slezko were in the last row of benches, giving The Invalid an extra four eyes. The day before a port call was always the most anxious, when it could be cancelled for any number of reasons: time did not permit, money transfers had not been completed, the political climate wasn't right.

The anticipation of Dutch Harbor had gripped everyone. It was not only the first land in more than four months; it was the point of the entire voyage, those blessed few hours with foreign currency in an American store. If a man wanted to catch fish or a woman wanted simply to clean them, they could trawl the Soviet coast rather than spend half a year in the Bering Sea. The women were wearing freshly laundered blouses with flower prints coming into bloom, their hair spiked with pins. The men were more divided. The ship had gathered speed for the long run to the Aleutians, incidentally firing its boilers for showers, and half the men were scraped clean and sporting the knit shirts of men at ease. The other half, sceptics, still wore a crust of beard and dirt.

'Religion', Natasha read from a pamphlet, 'teaches that work is not a freely given contribution to the state, but an obligation imposed by God. A citizen who holds this view is unlikely to economize on materials.'

Obidin spoke up from the middle row of tables. 'Did God economize when He made heaven and earth? When He made the elephant? Maybe God doesn't care about economizing on materials.'

'Materials of the state?' Natasha was outraged.

'Why are you trying to subvert her?' Volovoi had sidled up to Arkady. 'She's a simple worker. Why drag her into this dirty work of yours?'

Natasha had dragged Arkady to the lecture. Not that he could have resisted; he was standing because he was afraid if he sat he wouldn't be able to rise, His arms were crossed over feverish tremors.

People shouted at Obidin, 'Shut up! Listen and learn!'

'Two days ago half the ship didn't know who you were,' Volovoi went on. 'Now you're the most hated man on board. You've outsmarted yourself. First you say Zina Patiashvili was murdered. Now you can't let these people, your own shipmates, have their port call without saying she wasn't.'

'Someone's been spreading the story that it's up to me,' Arkady said.

'Rumour always has a thousand tongues,' Volovoi observed. He looked at his watch. 'Well, you have eleven hours before your great decision: Dutch Harbor or no Dutch Harbor? Will you admit to error or put yourself above your entire ship? Others might say you will compromise. I don't know you in particular, but I know your type. I think you'd keep this whole crew anchored off Dutch Harbor and not let a single man on shore rather than confess that you're wrong.'

'Science has shown,' Natasha was saying, 'that the flame of a church candle induces an hypnotic effect. In comparison, science is the electrification of the mind.'

'After all,' Volovoi asked, 'what do you have to lose? You have no Party card, no family.'

'You have a family?' Arkady was interested. He saw The Invalid's apartment in a Vladivostok highrise, a spiritless wife, a litter of little Volovois in red Pioneer scarves gathered at the glow of a television set.

'My wife is second secretary of the City Soviet.'

Erase the spiritless wife, Arkady thought. Enter a match for Volovoi, the hammer and anvil from whom the next generation of Communists would be pounded out.

'And a boy,' Volovoi added. 'We have a stake in the future. You don't. You're the bad apple and I don't want you infecting Comrade Chaikovskaya.'

Natasha progressed from the electrification of the mind to the evolution of the flesh, from Homo Erectus to Socialist Man. Her refresher course in atheism had been ordered up because of the old Orthodox church in Dutch Harbor, pitting science against ghosts.

'What makes you think I can infect her?'

'You're glib,' Volovoi said. 'You had an important father, went to special schools in Moscow, had everything the rest of us didn't. You may impress her - you may even impress the captain - but I see you for what you are. You're anti-Soviet. I can smell it on you.'

'There's no difference,' Natasha was saying, 'between belief in a "supreme intelligence" and the faddish interest in aliens from other galaxies.'

Someone protested. 'Statistically there has to be life in other galaxies.'

'But they're not visiting us,' Natasha said.
