"It's the elevator shaft!" Hart had cried.
"The what?"
"Greta and I followed this downward to the lake where we found the drug that seems to be saving your life! We entered it halfway up, while this tunnel breaks into its top. The two cave entrances are connected!"
"Wonderful. By a pit so deep we can't even see the bottom."
Hart had shone his light around. "The chimney is hundreds of feet deep, but not bottomless. And look, it has ledges and handholds. Halfway down is the horizontal tunnel Greta and I entered before. This shaft can lead us back through the mountain to the caldera. While we're there I can even return to the lake and get some of the drug— now that we know it works."
"You want me to climb down there?"
"Only halfway. If the Germans have any sense they brought the Schwabenland back into the lagoon once they realized the seriousness of the storm. We'll walk out and meet them."
"And if they don't have any sense, which is my judgment of this entire expedition?"
"Then you wait by the spring while I climb back over the rim of the volcano to get the airplane. In the meantime you'll have more medicine."
"Why am I letting you talk me into climbing a sheer cliff?"
"Because that direction is all downhill." He clapped Fritz on the back. "Don't worry, we'll rope up."
"Ah. We can fall together."
Fritz actually did fine until the small volcanic earthquake came. Then the cave wall shuddered and a few loosened fragments of rock cut through the air past them, exploding into stony shrapnel somewhere far below. Now the sailor was trembling. "I don't like caves!"
"We're almost out of this one, Fritz." The pilot shone his flashlight. "See? There's the ledge we're making for. Much closer than trying to go back. The cave is unstable, but we won't be here long."
"Christ. I'm never getting off the ship again. I don't care what Pig-Head orders."
"You'll already be a hero. You won't have to."
Hart drove a final piton into the rock and threaded the rope through it, then led Fritz down its double length. On the sandy ledge where he and Greta had hesitated— it seemed like centuries ago— he reeled in the line. The pilot was cheerful. He'd be seeing her again soon.
The pair walked to the entrance of the crater's cave, blinking in the gray light of a new dawn. The storm was dying but wind still whistled up on the crater rim and spray pounded the caldera entrance. There was no sign of the Schwabenland, which was worrisome. But if Drexler was as patient as promised, it should still be waiting at sea. At least Hart hoped so. "I'll go quickly down to the lake to get you enough of the organic mats. If they still haven't returned by the time I get back I'll get the airplane. The storm should be completely over by then. Then I'll find the ship. Meanwhile, just get some sleep."
Fritz looked out tiredly, utterly spent. "You know, Owen, we're not the two most popular members of this cruise. Do you really think they'll wait?"
"Of course. Greta will make them wait."
Later that morning Jürgen Drexler and his volunteers sailed the frost-coated motor launch through the heaving swells of the caldera entrance, the open boat surprisingly stable as it surfed the breaking waves into the choppy lagoon. Except for the scattered crates of abandoned supplies onshore that formed a mournful monument to a seemingly thwarted mission, the crater was empty: Hart was deep in the heart of the mountain and Fritz was asleep. Drexler used his binoculars to scan the crater rim. No one waved or shouted.
The political liaison was put on shore with Feder to climb up the crater wall while the remaining volunteers motored to the Bergen to ready it with explosives. The two Germans hiked steadily to the top, the geographer panting hard, and came tentatively over the crest. Feder's urge to cringe from an imaginary assault of germs was dampened by a stiff wind that blew from their backs, sweeping the mysterious menace of the dry valley away from them. Even so, both wore a gauze mask, sticky on the inside and frosted on its surface.
The valley was desolate and deserted: as deserted as Drexler had secretly hoped. As the hours had ticked by on the ship, the idea that the annoying American might not be coming back had filled the political liaison with rising excitement. It would solve so many problems! Still, he hiked along the rim to make sure. He had to know, for both Greta and himself. After a quarter mile he found the radio that Fritz had hauled up from the valley bottom, snow-crusted and abandoned a hundred yards below the rim.
"I'm not going near it," Feder said.
"Then wait here. We must check." Drexler slid down the outer slope, sweating at even this tentative descent into the valley of death, but he made himself do it. A try revealed that the radio's batteries had died in the cold; he couldn't reach the ship. Otherwise there was no sign of Fritz, Hart, or the mountaineers. Drexler considered a moment, then climbed back and pointed along the rim.
"We hike on."
Feder unconsciously had backed a foot away from him, as if he might already be contaminated. "For God's sake, Jürgen, they're gone! Lost!"
"No. I want a view along the ridgeline of the valley."
Drexler's heart initially sank when they spied the flying boat. So, the pilot hadn't crashed. The Germans could see it tethered on the snow far below and studied it carefully for a sign of life. It was a quiet relief that they saw none. The plane was crusted with snow, its surroundings trackless. Hart had obviously left before the storm and not come back.
"Do you see anything?" Drexler asked, lowering his binoculars.
"Only an abandoned airplane. My God, wouldn't Hart have returned by now if he's still alive? He said four hours and it's been a day!"
The political liaison nodded, glad to have a witness. "Perhaps we should climb down and inspect," he offered carefully.
"No! The launch might leave us! Do you want us all to die, one by one, looking for each other? I'm going no nearer that pestilence than right here. It's time to go back!"
Drexler made a show of reluctance, looking out across the island with binoculars. Then, "You're right, Alfred. Even Hart advocated prudence." It was obvious, he told himself. The American had landed, descended into the valley, and died from the microbe or exposure. As much as he would like fresh tissue samples of the disease, it would be suicide to search for the bodies. It was over. His rival was dead.
He exhaled, realizing how tensely he had been holding his body. "So. We saw the plane abandoned and no sign of life. Agreed?"
"I told him not to come."
"We'd better return to the launch. They'll be wondering what happened to us."
"Finally. I'm freezing." When they turned the wind was bitter in their faces. Jürgen led the way back, brooding as he turned events over in his mind. The whole episode was a tragedy, yes. He was willing to admit that. But who could have foreseen that a simple scouting expedition would lead to so many deaths? And they'd learned valuable lessons to prepare them for return: his men hadn't died in vain. The disaster demonstrated the power of this strange new microbe, potentially an awesome new weapon!
He continued to muse as he and Feder picked their way down the slope. Atropos Island: the Fate that scheduled death, the Fate that was going to resurrect his career once he restored the cultures by returning next year. Too, by consigning Hart to some unknown end, Fate had resurrected his relationship with Greta. After reviewing the chain of events, his conscience was clear. Everyone had done the right thing as best they were able. Everyone.
