'Just resting lightly.' He rose from his chair and picked up his breathing equipment. 'Have no fears, Doc. With torpedoman first class Rawlings by your side — '
'We have plenty of fresh men still available aft, Dr.Carpenter,' Swanson said.
'No. Rawlings. It's for his own sake. Maybe he'll get two medals now for this night's work.'
Rawlings grinned and pulled the mask over his head. Two minutes later we were inside the engine room.
It was stiflingly hot in there, and visibility, even with the powerful beam of our flashlights, didn't exceed eighteen inches; but for the rest it wasn't too bad. The breathing apparatus functioned well enough, and I was conscious of no discomfort. At first, that was.
Rawlings took my arm and guided me to the head of a ladder that reached down to the deck of the machinery space. I heard the penetrating hiss of a fire extinguisher and peered around to locate its source.
A pity they had no submarines in the Middle Ages, I thought; the sight of that little lot down there would have given Dante an extra fillip when he started in on his Inferno. Over on the starboard side, two very powerful floodlights had been slung above the huge turbine: the visibility they gave varied from three to six feet, according to the changing amount of smoke given off by the charred and smoldering insulation. At the moment, one patch of the insulation was deeply covered in a layer of white foam — carbon dioxide released under pressure immediately freezes anything with which it comes in contact. As the man with the extinguisher stepped back, three others moved forward in the swirling gloom and started hacking and tearing away at the insulation. As soon as a sizable strip was dragged loose the exposed lagging below immediately burst into flame reaching the height of a man's head, throwing into sharp relief weird masked figures leaping backward to avoid being scorched by the flames. And then the man with the CO2 would approach again, press his trigger, the blaze would shrink down, flicker, and die, and a coat of creamy white foam would bloom where the fire had been. Then the entire process would be repeated all over again. The whole scene with the repetitively stylized movements of the participants highlit against a smoky, oil-veined background of flickering crimson was somehow weirdly suggestive of the priests of a long-dead and alien culture offering up some burnt sacrifice on their blood-stained pagan altar.
It also made me see Swanson's point: at the painfully but necessarily slow rate at which those men were making progress, four hours would be excellent par for the course. I tried not to think what the air inside the Dolphin would be like in four hours' time.
The man with the extinguisher — it was Raeburn — caught sight of us, came across, and led me through a tangled maze of steam pipes and condensers to where Ringman was lying. He was on his back, very still, but conscious: I could see the movement of the whites of his eyes behind his goggles. I bent down till my mask was touching his.
'Your leg?' I shouted.
He nodded.
'Left?'
He nodded again, reached out gingerly, and touched a spot halfway down the shinbone. I opened the medical case, pulled out scissors, pinched the clothes on his upper arm between finger and thumb, and cut a piece of the material away. The hypodermic came next and within two minutes he was asleep. With Rawlings' help, I laid splints against his leg and bandaged them roughly in place. Two of the fire fighters stopped work long enough to help us drag him up the ladder, and then Rawlings and I took him through the passage above the reactor room. I became aware that my breathing was now distressed, my legs shaking, and my whole body bathed in sweat.
Once in the control center, I took off my mask and immediately began to cough and sneeze uncontrollably, tears streaming down my cheeks. Even in the few minutes we had been gone, the air in the control room had deteriorated to a frightening extent.
Swanson said, 'Thank you, Doctor. What's it like in there?'
'Quite bad. Not intolerable, but not nice. Ten minutes is long enough for your fire fighters at one time.'
'Fire fighters I have plenty of. Ten minutes it shall be.'
A couple of burly enlisted men carried Ringman through to the sick bay. Rawlings had been ordered for'ard for rest and recuperation in the comparatively fresh air of the mess room, but he elected to stop off at the sick bay with me. He'd glanced at my bandaged left hand and said, 'Three hands are better than one, even though two of them do happen to belong to Rawlings.'
Benson was restless and occasionally murmuring but still below the level of consciousness. Captain Folsom was asleep, deeply so, which I found surprising until Rawlings told me that there were no alarm boxes in the sick bay and that the door was completely sound-proofed.
We laid Ringman down on the examination table, and Rawlings slit his trouser leg with a pair of heavy surgical scissors. It wasn't as bad as I had feared it would be: a clean fracture of the tibia, not compound. With Rawlings doing most of the work, we soon had his leg fixed up. I didn't try to put his leg in traction; when Jolly, with his two good hands, had completely recovered, he'd be able to make a better job of it than I could.
We'd just finished when a telephone rang. Rawlings lifted it quickly before Folsom could hear it, spoke briefly, and hung up.
'Control room,' he said. I knew from the wooden expression on his face that whatever news he had for me, it wasn't good. 'It was for you. Bolton, the sick man in the nucleonics lab, the one you brought back from Zebra yesterday afternoon. He's gone. About two minutes ago.' He shook his head despairingly. 'My God, another death.'
'No,' I said. 'Another murder.'

The «Dolphin» was an ice-cold tomb. At half-past six that morning, four and a half hours after the outbreak of the fire, there was still only one dead man inside the ship — Bolton. But as I looked with bloodshot and inflamed eyes at the men sitting or lying about the control room — no one was standing any more — I knew that within an hour, two at the most, Bolton would be having company. By ten o'clock at the latest, under those conditions, the «Dolphin» would be no more than a steel coffin with no life left inside her.
As a ship the «Dolphin» was already dead. All the sounds we associated with the living vessel, the murmurous pulsation of great engines, the high-pitched whine of generators, the deep hum of the air-conditioning unit, the unmistakable transmission from the sonar, the clickety-clack from the radio room, the soft hiss of air, the brassy jingle from the juke box, the whirring of fans, the rattle of pots from the galley, the movement of men, the talking of men — all those were gone. All those vital sounds, the heartbeats of a living vessel, were gone; but in their place was not silence but something worse than silence, something that bespoke not living but dying, the frighteningly rapid, hoarse, gasping breathing of lung-tortured men fighting for air and for life.
Fighting for air. That was the irony of it. Fighting for air while there were still many days' supply of oxygen in the giant tanks. There were some breathing sets aboard, similar to the British Built-in Breathing System, which takes a direct oxynitrogen mixture from tanks, but only a few, and all members of the crew had had a chance at those, but only for two minutes at a time. For the rest, for the more than ninety per cent without those systems, there was only the panting, straining agony that leads eventually to death. Some portable closed-circuit sets were still left, but those were reserved exclusively for the fire fighters.
Oxygen was occasionally bled from the tanks directly into the living spaces, and it just didn't do any good at all; the only effect it seemed to have was to make breathing even more cruelly difficult by heightening the atmospheric pressure. All the oxygen in the world was going to be of little avail as long as the level of carbon dioxide given off by our anguished breathing mounted steadily with the passing of each minute. Normally, the air in the Dolphin was cleaned and circulated throughout the ship every two minutes, but the giant 200-ton air conditioner responsible for this was a glutton for the electric power that drove it; and the electricians' estimate was that the reserve of power in the standby battery, which alone could reactivate the nuclear power plant, was already dangerously low. So the concentration of carbon dioxide increased steadily toward lethal levels, and there was nothing we could do about it.
Increasing, too, in what passed now for air, were the Freon fumes from the refrigerating machinery and the hydrogen fumes from the batteries. Worse still, the smoke was now so thick that visibility, even in the for'ard parts of the ship, was down to a few feet, but that smoke had to remain also; there was no power to operate the
