Chapter 20 The Tide Always Returns

Nikolai surfaced to find the sea flat and the sky the color of old tin. He pulled himself onto the dive platform, chest heaving, and Dmitri was there with a towel before his knees had locked. You were under for forty-three minutes, Dmitri said. The tide gave you fifty-one. You left eight on the table. Nikolai stripped off his gloves and sat on the rail, letting the wind dry his face. Down there, he said, the water curtain parted for me again. It recognized me. Dmitri handed him a mug of tea, black and bitter, and waited. It was the same nod it always gave, Nikolai continued. A hand's width, then closed. Like two professionals acknowledging each other across a gap. I disturbed nothing. I took nothing. The stern letters are the same. The frame is the same. The box would still be there if I had left it. Volkov climbed up from the engine room, grease on his forearms, and caught the last of it. The Svetlana is not going anywhere, he said. Neither are we, Dmitri said. The fuel contract is signed. We sail for Novorossiysk at first light. The equinox gales will be here in ten days. Nikolai wrapped both hands around the mug and let the heat seep into his fingers. He thought about the students who had written to him — a girl in Odessa, a retired sonar operator near Gdansk, a hieromonk in a monastery on Mount Athos. Letters arrived daily now, carried by pilot boats and satellite relays, each one asking the same question in different words: what does it mean? He had answered some. He had ignored most. He had no answers that were not already in the Archive, already public, already shared with every soul who wanted them. The rest was interpretation, and interpretation was the work of a generation, not of one diver with a brass cylinder. What about the second cipher? Volkov asked. He said it quietly, almost to himself, as though the question were a stone he had been turning over in his pocket for weeks. Nikolai looked at him. There is no second cipher. Azarov left one Archive. We published it. That is the whole of it. You do not believe that. Nikolai set the mug down on the rail. He did not believe that. He had spent seven years decoding the first cipher, and in that time he had learned the shape of Azarov's mind — the compulsive layering, the nested redundancies, the way the cartographer embedded traps inside traps. A man who built a vault beneath the sea floor and sealed it with a water curtain did not stop at one hiding place. But the Archive was complete. Every page, every diagram, every marginal notation — they had photographed and published the lot. If a second cipher existed, it was outside the Archive, outside the cylinder, outside the wreck. It was somewhere else entirely. We look when we are ready, Nikolai said. Not before. Dmitri climbed to the bridge with a fuel contract in his fist and came down ten minutes later having extracted, by his own account, a kopeck of respect from a man who sold petroleum the way other men sold weather. They ate dinner in the galley — fish stew, black bread, a bottle of Crimean wine that Oksana had been saving for a celebration she refused to name. The crew talked about the Archive the way crews talk about weather: as a fact of life that had changed their plans but not their routines. Misha asked whether the sphere had spoken to Nikolai on the dive. It never speaks, Nikolai said. It listens. Then what does it hear? Everything, Volkov said. He poured wine into Nikolai's cup and raised his own. To the Archive. To the Archive, Dmitri echoed. To the archive, Misha added, and the cook, who had been silent all evening, nodded once from the doorway and went back to his tins. They sailed at first light on the morning ebb, bound for Novorossiysk to provision and to lie out the equinox gales in a harbor with good holding ground. Before the autumn storms closed the season, Nikolai went down to the Svetlana one last time. The tide gave him fifty-one minutes, generous by its recent standards, and he spent them without hurry — a slow circuit of the hull with the camera running, one final measured set of photographs of the stern letters, a long pause at the iron frame where the box had waited three centuries for a hand. He disturbed nothing and took nothing. At the rim of the depression he stopped, and the curtain of water shimmered once across the doorway, parting a hand's width before closing again, less an invitation than a nod exchanged between professionals, and he inclined his head inside the helmet and turned for the guide line. Aboard, the Akademiya was already becoming a ship between seasons. Engineers greased the winches under tarps, the cook inventoried tins with monastic gravity, and Volkov spread the Aegean tide tables across the mess table and began circling dates in red pencil, muttering about winter lows and ferry schedules as though the Mediterranean were a difficult colleague who would have to be won over by correspondence. From the foredeck Nikolai watched the Crimean coast diminish into its own haze — the cliffs, the seam of surf, the fairway buoy leaning patiently to the current — and felt the peculiar gratitude of a man taking leave of a place that had never once pretended to be kind to him. Behind the ship the wreck settled back into its keeping dark, doorway sealed in water and patience, its lessons distributed now among millions of strangers who would never stand where he had stood and who would understand parts of it better than he ever would. Ahead the sea ran long and gray-green toward the strait, roughened with the morning's small confusions of wind, and somewhere along that reach lay other wrecks, other ciphers, other mornings when the tide would fall far enough to show what it had been hiding. Volkov came forward and leaned on the rail beside him, and for a while neither spoke, because the ship was speaking — steady, deliberate, aimed at open water like a sentence that refuses to stop at the first comfortable period. That evening, in the chart room with the compass from the wool sock now lashed above the table, Nikolai did something he had been turning over since Sevastopol: for the first time since the cafe, he dialed the nine digits of Pavel's number from memory, and when the click came he asked, without preamble, what his old colleague knew about Byzantine manuscript collections in Istanbul.
