Icebound

It was stuck firmly to the locker wall. When he tore it free, he saw that six loops of electrician's tape had held it fast, so it had been placed there with considerable deliberation, in hope of keeping it a secret even if the locker was violated.

The flap was held shut only by a metal clasp, and Gunvald opened it. The envelope contained only a spiral- bound notebook with what appeared to be newspaper and magazine clippings interlarded among the pages.

Reluctantly but without hesitation, Gunvald opened the notebook and began to page through it. The contents hit him with tremendous force, shocked him as he had never imagined that he could be shocked. Hideous stuff. Page after page of it. He knew at once that the man who had compiled this collection, if not a raving maniac, was at least a seriously disturbed and dangerous individual.

He closed the book, yanked the chain to turn out the light at the back of the room, and hurriedly pulled on his coat and outer boots. Kicking through snowdrifts, head tucked down to protect his face from a savage wind filled with flaying specks of ice, he ran back to the telecommunications hut, frantic to let Harry know what he had found.

“Ice overhead. One hundred feet.”

Gorov left the command pad and stood behind the technician who was reading the surface Fathometer.

“Ice overhead. One hundred twenty feet.”

“How can it be receding?” Gorov frowned, reluctant to believe the proof provided by the very technology that he had always trusted. “By now the iceberg's turned its narrow profile to us, so we can't have passed under even half its length. There's still a huge, long mountain hanging over us.”

The technician frowned too. “I don't understand it, sir. But now it's up to a hundred and forty feet and still rising.”

“A hundred and forty feet of clear water between us and the bottom of the iceberg?”

“Yes, sir.”

The surface Fathometer was a sophisticated version of the echo sounder that had been used for decades to find the floor of the ocean beneath a submarine. It broadcast high-frequency sound waves upward in a tightly controlled spread, bounced an echo off the underside of the ice — if any actually lay overhead — and determined the distance between the top of the sail and the frozen ceiling of the sea. It was standard equipment on every ship that might possibly be called upon — on rare occasions, if ever — to pass under the icecap in order to fulfill its duties or to escape an enemy vessel.

“One hundred sixty feet, sir.”

The stylus on the surface Fathometer wiggled back and forth on a continuous drum of graph paper. The black band that it drew was steadily growing wider.

“Ice overhead. One hundred eighty feet.”

The ice continued to recede above them.

It made no sense.

The squawk box above the command pad hissed and crackled. The voice that issued from it was gruff by nature and metallic, as all voices were that passed through the intercom. The torpedo officer reported news that Nikita Gorov had hoped never to hear at any depth. Let alone at seven hundred forty feet: “Captain, our forward bulkhead is sweating.”

Everyone in the control room stiffened. Their attention had been riveted on the ice reports and on the sonar readings, because the greatest danger had seemed to be that they would ram into a long stalactite of ice hanging from the bottom of the berg. The torpedo officer's warning was an unnerving reminder that they had collided with an unknown mass of drift ice before initiating a crash dive and that they were more than seven hundred feet beneath the surface, where every square inch of the hull was under brutal pressure. Millions upon millions of tons of seawater lay between them and the world of sky and sun and open air that was their true home.

Pulling down an overhead microphone, Gorov said, “Captain to torpedo room. There's dry insulation behind the bulkhead.”

The squawk box was now the center of interest, as the diving gauge had been a moment ago. “Yes, sir. But it's sweating just the same. The insulation behind it must be wet now.”

Evidently they had sustained a dangerous amount of damage when they had collided with that floe ice. “Is there much water?”

“Just a sweat, sir. Just a film.”

“Where did you find it?”

The torpedo officer said, “Along the weld between number four tube and number five tube.”

“Any buckling?”

“No, sir.”

“Watch it closely,” Gorov said.

“I've got eyes for nothing else, sir.”

Gorov let go of the microphone, and it sprang back up out of the way.

Zhukov was at the command pad. “We could change course, sir.”

“No.”

Gorov knew what his first officer was thinking. They were passing under the length of the iceberg, with half of it — at least two fifths of a mile — still ahead of them. To port and starboard, however, open water could be found in two or three hundred yards, for the width of the berg was substantially less than its length. Changing course seemed reasonable, but it would be a waste of effort.

Gorov said, “By the time we could bring the boat around and to port or starboard, we'd have passed under the iceberg's stern and would be in open water anyway. Hold tight, Lieutenant.”

“All right, sir.”

“Rudder amidships, and keep it that way unless the current begins to push us around.”

The operator seated at the surface Fathometer announced. “Ice overhead. Two hundred fifty feet.”

The mystery of the receding ice again.

They were not descending. And Gorov knew damned well that the iceberg above them was not magically levitating out of the sea. So why was the distance between them steadily widening?

“Should we take her up, sir?” Zhukov suggested. “A little closer to the ice. If we ascend even to just six hundred feet, that torpedo-room bulkhead might stop sweating. The pressure would be considerably less.”

“Steady at seven hundred forty,” Gorov said shortly.

He was more worried about his sweating crew than he was about the sweating bulkhead. They were good men, and he'd had many reasons to be proud of them during the time that they had served under him. They'd been in numerous tight spots before, and without exception they had remained calm and professional. On every previous occasion, however, they had needed nothing but nerve and skill to see them through. This time a big measure of good luck was needed as well. No amount of nerve and skill could save them if the hull cracked under the titanic pressure to which it was currently being subjected. Unable to rely solely on themselves, they were forced to trust also in the faceless engineers who had designed the boat and the shipyard workers who had built it. Perhaps that would not have been too much to ask if they had not been acutely aware that the country's troubled economy had led to a reduction in the frequency and extent of dry-dock maintenance of the vessel. That was enough to make them a bit crazy — and perhaps careless.

“We can't go up,” Gorov insisted. “There's still all that ice above us. I don't know what's happening here, how the ice can be receding like this, but we'll be cautious until I understand the situation.”

“Ice overhead. Two hundred eighty feet.”

Gorov looked again at the surface Fathometer graph.

“Three hundred feet, sir.”

Abruptly the stylus stopped jiggling. It produced a straight, thin, black line down the center of the drum.

“Clear water!” the technician said with obvious astonishment. “No ice overhead.”

“We're out from under?” Zhukov asked.

Gorov said, “Impossible. That's a monster berg at least four fifths of a mile long. No more than half of it has passed over us. We can't—”
