"Oh, hurry, Mr. Wells!" he yelled. "Quick! Quick, please! The octopis ship's comin', sir! The red light's back!"

CHAPTER XI

_To the Death_

The emergency steadied Keith's fingers. He got the door open and motioned Graham and six men inside the water chamber. The pa.s.sage took but a minute. Then he sent the rest of the crew in, being himself the last to enter. When the chamber was finally empty, and Wells had stepped through the inner door onto the lower deck of the _NX-1_, a great sigh of relief broke from him. Never before had anything looked so good as that brilliantly lit deck with its familiar maze of machinery and bulkheads.

"Thank G.o.d," he said simply, and his joy was shared by the whole crew.

A new feeling had come over them. Back home--in their own submarine, their own element--they had at least a fighting chance with the octopi. But Keith let them waste no time. He knew that a final, desperate duel to the death with their foe still was ahead. "Above to the control room," he ordered. "Fast!"

They lumbered up the connecting ramp. A disheveled, wild-eyed form met them. Keith couldn't help chuckling as he pa.s.sed the now much thinner and paler cook, with the a.r.s.enal handy at his waist. On the deck of the control room lay a huge tentacled body, metal-scaled, with its dome of gla.s.s shattered and its great cold eyes staring unseeingly away. "I killed him," stammered McKegnie pridefully; "but Mr.

Wells--look at that red light, sir!"

Keith glanced rapidly at the location chart, ripping off his sea-suit as he did. The fateful red stud was moving swiftly down on the motionless green one. The men had surrounded McKegnie, laughing and slapping him on the back, but the commander's terse orders jerked them abruptly back to action.

"The rectifiers, Graham: clean out this stale air. Sea-suits off; at emergency posts. Take the helm, Craig; you, Wetherby, trim the ship.

No, no, Cook--keep away from the controls!"

The _NX-1_ balanced herself; fresh air came rushing in, sweeping out the stale. Keith stared at the location chart, waiting for the submarine to be ready. The red light was almost upon them.

"Right!" he roared at last. "Diving rudder controls, Graham! Full speed for the tunnel!"

At that moment the octopi ship swept into view, its full battery of offensive weapons flaring forth. The paralyzing ray tingled again and again over the control room. Someone laughed at its uselessness. The violet heat ray leveled full at them, but the commander avoided it with "Port ten, starboard ten! Maintain zigzag course to the tunnel."

He understood the enemy's weapons now; he was throbbing with the fierce thrill of action. This duel was to be the climax of their whole adventure. "And, by heaven," he promised, "it's going to be a fight!"

The other craft seemed to realize the _NX-1_ was now in expert hands.

She raced along to starboard for some minutes, her heat ray trying vainly to steady on the American's weaving form. Wells wondered if the king of the octopi was aboard her, in command; he thought perhaps the ship had postponed her chase of McKegnie to pick him up. "I hope he is!" the commander breathed, and fingered the torpedo lever. He had some debts to pay.

The _NX-1_, engines working smoothly, proceeded on a desperate dash for the tunnel that led to the outer sea. But the octopi ship apparently knew what Keith intended, for she abandoned her offensive rays, changed course a few degrees and slowly but steadily pulled ahead. "d.a.m.n!" Keith exclaimed. "She'll get there before us!"

The dim shape dwindled on the screen, and before long her bulk had disappeared entirely. Wells then could watch her swift, straight progress only on the location chart.

Ten minutes later the funnel-like opening of the tunnel loomed on the teleview, and squarely in front, blocking it, was the waiting form of the octopi submarine.

"Quarter speed!" Keith snapped. "Hold her steady, Graham; I'm going to try a bow torpedo. I think we're beyond their ray."

Sighting his range on the telescopic range-finder, he worked the _NX-1_ slowly into position. He noticed that his first officer was staring oddly at him. He was bothered by the queer look. "What's wrong?" he asked impatiently.

"But--what about Hemmy Bowman?"

Bowman! In the rush of action and suspense, Keith Wells had completely forgotten his officer in the enemy submarine. "Oh, G.o.d!" he groaned.

The cruel situation that had stayed his hand once before had again come to falter his course of action. The men were watching him; Graham had a question in his eyes. They all knew what had to be decided....

Keith shrugged his shoulders hopelessly. It was his greater duty to destroy the octopi submarine. And yet--

"Fish for Hemmy, Sparks," he ordered. "Craig, keep present distance from enemy. Full stop."

A moment later the radio operator looked up. "Mr. Bowman on the phones, sir." With a heavy weight on his heart the commander clipped on the extension headphones.

"Hemmy?"

"Keith? Keith? Thank G.o.d you're alive!" Bowman's voice shook with gladness. "You're all back on the _NX-1_, Keith? The whole crew's with you? Oh, Lord, it's good to hear you again!"

"Yes. We got back all right, Hemmy--a miracle. They've still got you prisoner?"

"Yes.... Keith--you're trying to dodge out of the tunnel, aren't you?"

Wells smiled bitterly, and as he paused to frame an answer Bowman spoke again.

"I want you to blow up this submarine, Keith," he said quickly. "A favor to me."

He cut Wells short when the commander started to interrupt. "Wait! Let me finish," he pleaded. "I want to explain. I'd been hoping--but never mind that.... Keith, a while ago I managed to work loose. I lost my head completely and tackled these devils. It was a foolish thing to do; they overcame me, naturally. But, in the struggle, they tore my sea-suit."

"What!"

"Oh, just a tiny tear, or I wouldn't have lasted till now. But a leak all the same--in the right leg. Since then I've been gripping the edges of the fabric as tightly as I can--but I couldn't keep the water inside this ship from seeping through. It came in slowly at first, then faster as my hands grew numb. It's up to my neck now, Keith ...

and--it won't be long! I've just a few minutes left...."

The faint words tapered into silence.

"No!" roared Keith in a great rush of emotion. But Hemmy's eager voice came right back:

"Oh yes, you must! It would be a mercy to kill me, Keith."

There were tears in the commander's eyes. "Are you sure, Hemmy?" he asked. "Are you sure?"

"Oh, yes. It would be a mercy."

Wells' lips formed a straight grim line. His words squeezed through it tightly. "All right, Hemmy. Thanks. Thanks. I--I'll go after them now, old man. I'll try and keep in touch with you through the duel, but I--I can't promise--"

He could almost see Hemingway Bowman give his old familiar smile as he answered:

"Then so long, Keith!"

Commander Keith Wells studied the teleview screen. The men were half afraid to look at his strained blanched face.

Repeatedly the violet beam speared through the water, reaching for the _NX-1's_ bow.

"Turn ship. Line up for stern torpedoes," the commander ordered harshly. He realized he could not hold his submarine steady to obtain a perfect sight, for the heat ray needed only thirty seconds to melt through their sh.e.l.l. He would have to swing the ship slowly about; and, as the shape of the enemy crossed the hair-lines on the range-finder, unleash his torpedoes and gamble on hitting the moving target.
