Ice Station Zebra
Alistair MacLean
 Drift Ice Station Zebra, a British meteorological station built on an ice floe in the Arctic Sea, has suffered a catastrophic oil fire; men have died and shelter and supplies have been destroyed. The survivors are holed up in one hut with little food and heat. If help does not reach them quickly, they will die. The (fictional) American nuclear-powered submarine USS Dolphin is dispatched on a rescue mission. Just before it departs, the mysterious Dr. Carpenter, the narrator, is sent to accompany it. Carpenter claims that he is necessary as an expert in dealing with frostbite and other deep-cold medical conditions. At first, the submarine's Captain Swanson is suspicious of Carpenter, even though he receives an order from Chief of Naval Operations of the U.S. Navy instructing him to obey Carpenter's every command except where crew and submarine safety is at stake. Swanson then calls in his boss Admiral Garvie. Admiral Garvie, Captain Swanson and Dr. Carpenter then meet in confidence in Captain Swanson's small cabin. Admiral Garvie questions Dr. Carpenter at length asking why a civilian and a non US Citizen should be allowed aboard the USS Dolphin and says that he can countermand the CNO's instructions and refuse transport to Dr. Carpenter. Carpenter is thus forced to reveal that this is not simply a rescue mission; the station is actually a highly-equipped listening post, keeping watch for nuclear missile launches from the Soviet Union. Hearing this, Admiral Garvie allows Carpenter to come along. Swanson asks Carpenter to dinner but Carpenter declines saying that he has been traveling for more than 50 hours. Swanson asks and Dr. Carpenter reveals that 50 hours ago he was in the Antarctic. It is very mysterious and Admiral Garvie gives an old fashioned look but he lets it go at that point. Before the Dolphin dives under the Arctic ice pack, it tries to contact Zebra, whose radio signals are becoming weaker by the hour, but in vain. Once under the Arctic ice pack, it approaches the calculated position for Zebra, then searches for a place to surface. Eventually finding a place where the ice is thin enough to break through, the Dolphin establishes tenuous radio contact, and gets a bearing on Zebra's position. But Zebra is too far away to attempt to reach it on foot, so the submarine re-submerges, hoping to get closer. Carpenter confides to the Captain that the commander of the station is his brother. After a tense, desperate search, the Dolphin finds open water and surfaces just five miles from the station. Carpenter, Executive Officer Hansen, and two crewmen make the perilous journey through an Arctic storm on foot, taking with them as many supplies as they can. Zabrinski, one of the crewmen, breaks his ankle on the way. After a harrowing trek they reach Zebra. Devastation awaits them. Three of the eight huts and almost all supplies have been destroyed by a widespread oil fire. Eight men are dead - burnt to a crisp. Eleven men are alive, but barely. While the victims are being tended to, Carpenter does some investigating on his own. Unable to make radio contact, as the radio was damaged in Zabrinski's fall, Carpenter just receives a message from the Dolphin telling them to return at once, as the ice is closing. Carpenter and Hansen leave Zabrinski and the other crewman to attend to the survivors. After nearly getting lost in the terrible storm of blowing ice, Carpenter and Hansen finally return to the Dolphin, bearing news of their findings, as well as the relatively thin ice nearer to Zebra. Dolphin submerges and heads for Zebra. The ice there is still too thick to break with the sub's sail, so Swanson decides to blow a hole in the ice with a torpedo. Unbeknownst to him, someone had tampered with the wiring of the indicators which indicated the open/close status of the outer tube doors. When the crew attempts to load a torpedo into one of the tubes, a torrent of water rushes through the inner door, killing an officer and sending Dolphin into a nearly catastrophic dive. Only by heroic measures is Dolphin able to save herself. After successfully breaking through the ice with a torpedo, fired from an UN-sabotaged tube, Dolphin finally emerges just two hundred feet from Zebra. The sick men are treated, but some of them are still too ill to be carried to the sub. Carpenter does some more investigating. He finds that the fire at Zebra was no accident; it was a cover to hide that three of the dead men, one of whom was his brother, were murdered. Carpenter already knows why; the only question is who. Swanson also has a look around and finds no trace of the sophisticated listening equipment Carpenter had claimed was Zebra's purpose &mdash; Carpenter had lied again. Meanwhile, Swanson found a loaded gun in the petrol tank of a tractor, where the petrol would keep it from freezing, whereas Carpenter found food, batteries and a powerful radio hidden in the hut being used as a morgue. Finally the survivors are all brought aboard, Zebra is abandoned, and Dolphin heads back, but not without several further incidents. The ship's doctor is knocked into a coma. Carpenter himself is severely hurt in another apparent accident. Then a fire breaks out in the engine room and the sub is forced to shut down its nuclear reactor. Without power for air purification or heating, Dolphin looks set to become a frozen tomb trapped under the ice pack. Only the ingenuity of Commander Swanson and the dedication of the crew saves the ship. Carpenter announces that the fire was no accident. He reveals to the Captain that he is an MI6 officer. Carpenter's real mission is to retrieve photographic film from a reconnaissance satellite (see Corona) that has photographed every nuclear weapons installation in the U.S. The film, ejected from the satellite, had landed near Zebra. Carpenter's brother had been meant to retrieve it, but Russian agents killed him. The two Russian agents are amongst the survivors from Zebra. Carpenter finally reveals their motives, methods, and the men. The film is now in American hands, and the agents on their way to the gallows.
