Cryptonomicon

He rips the life preserver off over his head and lets it go. It shoots straight up and bursts out of the surface, burning like a comet. His oil-soaked clothing is tugging him relentlessly upwards, so he rips his shirt off and lets it tumble up towards the surface. His boots pull down, his oily pants push up, and he reaches some sort of equilibrium.

He grew up in the mines.

Kulu is near the north coast of Hokkaido, on the shore of a freshwater lake where rivers converge from the inland hills and commingle their waters before draining to the Sea of Okhotsk. The hills rise sharply from one end of that lake, looming over a cold silver creek that rushes down out of forest inhabited only by apes and demons. There are small islands in that part of the lake. If you dig down into the islands, or the hills, you will find veins of copper ore, and sometimes you will find zinc and lead and even silver. That is what the men of Kulu have done for many generations. Their monument is a maze of tunnels that snake through the hills, not following straight lines but tracking the richest veins.

Sometimes the tunnels dip below the level of the lake. When the mines were working these tunnels were pumped out, but now that they are exhausted, the water has been allowed to seek its level and has formed sumps. There are cavities and tunnels back in the hills that can only be reached by boys who are brave enough to dive into the cold black water and swim through the darkness for ten, twenty, thirty meters.

Goto Dengo went to all of those places when he was a boy. He even discovered some of them. Big, fat and buoyant, he was a pretty good swimmer. He was not the best swimmer, or the best at holding his breath. He was not even the bravest (the bravest did not put on life preservers, and went to their deaths like warriors).

He went where the others wouldn't because he, alone among all the boys of Kulu, was not afraid of the demons. When he was a boy, his father, a mining engineer, would take him hiking up into the places in the mountains where demons were said to live. They would sleep out under the stars and wake up to find their blankets covered with frost, and sometimes their food stolen by bears. But no demons.

The other boys believed that demons lived in some of those underwater tunnels, and that this explained why some of the boys who swam back there never returned. But Goto Dengo did not fear the demons and so he went back there fearing only the cold and the dark and the water. Which was plenty to fear.

Now he need only pretend that the fire is a stone ceiling. He swims some more. But he did not breathe properly before diving, and he is close to panic now. He looks up again and sees that the water is burning only in patches.

He is quite deep, he realizes, and he can't swim well in trousers and boots. He fumbles at his bootlaces, but they are tied in double knots. He pulls a knife from his belt and slashes through the laces, kicks the boots off, sheds his pants and drawers too. Naked, he forces himself to be calm for ten more seconds, brings his knees to his chest and hugs them. His body's natural buoyancy takes over. He knows that he must be rising slowly toward the surface now, like a bubble. The light is growing brighter. He need only wait. He lets go of the knife, which is only slowing him down.

His back feels cold. He explodes out of the fetal position and thrusts his head up into the air, gasping for breath. A patch of burning oil is almost close enough for him to touch, and the oil is trickling across the top of the ocean as if it were a solid surface. Nearly invisible blue flames seep from it, then turn yellow and boil off curling black smoke. He backstrokes away from a reaching tendril.

A glowing silver apparition passes over him, so close he can feel the warmth of its exhaust and read the English warning labels on its belly. The tips of its wing guns are sparkling, flinging out red streaks.

They are strafing the survivors. Some try to dive, but the oil in their uniforms pops them right back to the surface, legs flailing uselessly in the air. Goto Dengo first makes sure he is nowhere near any burning oil, then treads water, spinning slowly in the water like a radar dish, looking for planes. A P-38 comes in low, gunning for him. He sucks in a breath and dives. It is nice and quiet under the water, and the bullets striking its surface sound like the ticking of a big sewing machine. He sees a few rounds plunging into the water around him, leaving trails of bubbles as the water cavitates in their wake, slowing virtually to a stop in just a meter or two, then turning downwards and sinking like bombs. He swims after one of them and plucks it out of the water. It is still hot from its passage. He would keep it as a souvenir, but his pockets are gone with his clothes and he needs his hands. He stares at the bullet for a moment, greenish-silver in the underwater light, fresh from some factory in America.
