Lawrence’s productivity as a cryptanalyst collapses after meeting Mary Smith, as his obsessive attraction disrupts his carefully regulated routines for mental clarity. He theorizes his desire and concentration in mathematical terms, concluding that traditional methods of managing sexual tension no longer work because thoughts of Mary override everything else. Guilt over visiting a sex worker deepens his self-loathing and forces him to confront social expectations and emotional vulnerability for the first time.

Pressured by Mrs. McTeague, he attends a dance to see Mary, nervously rehearsing technical conversation starters. There, he discovers that Mary and her cousin, Rod, speak Qwghlmian, a rare language secretly used by Allied forces as a code. Attempting to impress Mary by speaking it, he mangles the pronunciation and accidentally insults her, provoking a punch from her escort. Rod rescues him, explains the linguistic mistake in the “pithy language” (552), and reassures him, leaving Lawrence bruised, humiliated, and still deeply infatuated.

After six weeks recovering in a Catholic hospital in the mountains of Luzon, Goto Dengo slowly regains strength while brooding over suffering, faith, and his isolation. Surrounded by Christian imagery and other injured Japanese soldiers, he feels both spared and condemned, questioning why he was not permitted to “die honorably” (555). Conversations with Father Ferdinand expose cultural and moral clashes, as Goto interprets mercy as humiliation and spiritual pressure.

Declared cured, he is unexpectedly transported by plane and motorcycle south through the Philippine countryside toward Manila. Along the journey he observes occupied life, glimpses American propaganda, and senses growing resistance.

At a jungle checkpoint, he is abruptly diverted to a heavily fortified clearing. There, Lieutenant Mori reveals Goto’s new assignment: He is to use his mining expertise for a critical and secret operation. To preserve secrecy, the Filipino driver who brought him is executed. Goto realizes he has been selected for a crucial, ominous task at the heart of Japan’s hidden war effort.

Randy returns to San Francisco, enduring a tense customs inspection before reuniting with Avi. After, Avi reveals that Epiphyte’s future lies in “establishing a new currency” (563) backed by gold, prompted by Southeast Asia’s collapsing economies and the hidden gold Randy saw in the Philippines. Randy realizes his jungle expedition served as a “credit check” (565) by shadowy financiers seeking partnership. Their discussion also turns to Amy, whose emotional demands Avi conveys through his wife, prompting Randy to acknowledge unresolved personal obligations.

At Avi’s heavily secured home, Randy absorbs the scale of their intelligence operations and prepares to travel north, ostensibly for family matters involving his grandmother. He confesses that a cryptic wartime document referencing “WATERHOUSE LAVENDER ROSE” (569), found in a sunken Nazi submarine, is drawing him back to his family’s past. Randy sets off down the California coast.

After his bruises fade, Lawrence’s obsession with Mary intensifies, prompting a comic yet anxious crisis over sex, church, and social conformity. Convinced that society enforces an “Ejaculation Control Conspiracy” (570), he decides to attend church with Rod as a strategic step toward courting Mary.

At the Inner Qwghlmian church, he becomes fascinated by the malfunctioning pipe organ and volunteers to repair it. Confronted by a rambling, eccentric organist, Lawrence launches into a dazzling mathematical and musical demonstration, overwhelming the clergy and commandeering the instrument. He performs a thunderous, improvised rendition of Bach, simultaneously diagnosing the organ’s mechanical flaws. In a sudden intellectual breakthrough, he conceives “how to make electronic money” (576), solving a problem posed by Turing. Realizing the significance of his insight, he abruptly abandons the church to write to Alan, forgetting his shoes and momentarily leaving Mary behind.

After an earthquake destroys his California house, Randy awakens amid the wreckage with Amy and her cousins, who have taken refuge inside. They assess the devastation and realize the uninsured house is a total loss, wiping out much of Randy’s net worth. Despite the shock, Randy feels an unexpected calm.

Amy admits she chased him cross-country in anger and fear, mistakenly believing he was returning to his former partner, Charlene, and nearly ran him off the road to stop him from making “a big, stupid mistake” (581). Their emotional confrontation leads to a clearer understanding of each other and the failures of Randy’s previous relationship.

As they prepare to leave town, Randy reflects on his fractured social ties and the mixed reactions of old friends, noting how the only people who seem to have any concern for him are those whom he once dismissed for their religious beliefs. Driving slowly through the ruined streets, Randy finally “drives out of town forever” (586), leaving behind his former life and moving forward with Amy.

Captain Noda briefs Goto Dengo and Lieutenant Mori on a secret project called “Bundok,” unveiling detailed plans sketched on a bedsheet from a Manila Hotel. The site will be heavily secured, with dams, controlled access, worker housing, and a hidden “Special Security Zone” (588) under Goto’s command. Absolute secrecy is paramount and Mori is excluded from all sensitive details.

Though Goto initially imagines a mine or weapon, Noda reveals the true purpose: A vast underground storage complex carved into volcanic rock to protect vital war materials. Its scale is small but its defenses immense. Realizing Japan is preparing for eventual defeat, Goto believes the project resembles “a tomb for the emperor” (590). Haunted by this thought, he endures disturbing dreams, then resolves to begin his grim, monumental task.

Lieutenant Colonel Earl Comstock braces for Lawrence’s “routine” (590) briefing like a dangerous test, stocking coffee, Benzedrine, stenographers, wire recorders, photographers, and math aides to capture whatever happens.

Lawrence arrives barely functional after a morning at the church, then snaps into focus and asserts that the Japanese cipher Azure is identical to the German Pufferfish, related to a newer system he calls “Arethusa,” and tied to gold mining in the Philippines. Unable to break Azure directly, he claims he can extract meaning through large-scale statistical analysis of message traffic before and after Azure transmissions, tracing loops that repeatedly involve mining engineers and submarines.

The meeting spirals into hours of chalkboard mathematics. Lawrence reveals he used an immense electronic toll collection (ETC) machine run to crunch years of intercepts, then demonstrates his breakthrough: a mercury-and-organ-pipe RAM to “BURY and DISENTER” (598) data, making it a true digital computer. As Comstock absorbs this, Lawrence adds he is “engaged to be married” (600).

Randy, now unhoused after the earthquake, heads north to Washington with Amy and her cousins, Robin and Marcus Aurelius Shaftoe, forming an unlikely caravan. The Shaftoe boys insist on driving, guided by frugality, family loyalty, and a belief that abandoning their car would be morally wrong. Randy gradually realizes they think he is “utterly destitute” (603) and have adjusted their extreme thrift to spare him embarrassment. Over days of shared travel, they bond, especially Robin, who absorbs Randy’s ideas about the Internet, digital currency, and the global economy. Amy explains that her email to the extended Shaftoe family likely prompted the boys’ urgent cross-country rescue.

As Randy and Amy finally travel alone, they discuss family, loyalty, and business. Randy confides plans to launch a gold-backed electronic currency. The plan may make him rich, he says, but he mostly hopes that he is not “totally humiliated” (609).

Bobby spends months maneuvering back toward the war, evading reassignment by exploiting Marine solidarity and slipping through Pacific transport routes until he reaches Noumea, New Caledonia. Blocked by the boundary between Nimitz’s theater and General MacArthur’s SOWESPAC, he adapts by cultivating friendships with Fifth Air Force non-commissioned officers (NCOs) using cigarettes and barroom contacts. He finally stows away on a B-24 to Brisbane, endures severe cold in the tail turret, and arrives determined to reach the General.

Learning MacArthur has moved to Hollandia, New Guinea, Bobby loiters near Lennon’s Hotel until he intercepts a two-star general and is flown onward in Army greens. In Hollandia, amid Japanese strafing, he unexpectedly meets MacArthur, who is seemingly unperturbed by an ongoing air attack. The General tests Bobby’s Manila knowledge, then uses him as driver while he confronts anti-aircraft officers. He assigns Bobby a new mission: not primarily killing Japanese, but inspiring and coordinating Filipinos by carrying the message that MacArthur “shall return […] soon” (619).

Randy returns to Whitman, Washington, where the Palouse wind and winter “ice devils” (622) remind him how small disturbances can create persistent, chaotic patterns. He arrives at Waterhouse House, a dorm named for his grandfather, and joins his relatives to divide his grandmother’s belongings now that she has moved into long-term care.

To avoid endless fighting over price and sentiment, Uncle Red proposes a physical, mathematical ritual: Everyone places each item in a parking lot coordinate system, with the x-axis representing perceived financial value and the y-axis emotional value. The family argues immediately over a cherished console and Aunt Nina distrusts both appraisers and the planned computer-mediated solution. Randy explains the division resembles a hard optimization problem, so the final allocation will be computed using a powerful campus supercomputer named Tera.

Meanwhile, Nina maneuvers to secure a heavy trunk; Randy tries to stay objective but wants it. When his mother reveals a gravy boat marked “ROYAL ALBERT—LAVENDER ROSE” (633), Randy recognizes the phrase from the Nazi submarine note and starts plotting how to manipulate the outcome.

Lieutenant Ninomiya arrives at Bundok with pristine surveying instruments, relieving Goto Dengo, who has been mapping and sampling the terrain by hand. Goto, Mori, and Ninomiya survey the lower Tojo River to site roads, barracks, fences, towers, and mortar positions.

Under special permission, Ninomiya joins Goto in the hidden Special Security Zone to measure elevations and fix coordinates, climbing the cinder-cone “Calvary” (635) to take sun and mirror sightings. They plan Lake Yamamoto, an inclined shaft from the lakebed into tunnels, and routes for roads and rail lines, ensuring nothing is visible from the air.

Mori’s prison camp expands as Chinese prisoners arrive from Shanghai, not local Filipinos. Ninomiya then vanishes. Later, workers uncover a skull with a gold tooth and a bullet hole. He knows that Ninomiya is dead. Goto secretly buries him, distracts Noda, and names the shaft destination “Golgotha” (639), which he falsely says is a Tagalog word.

Randy learns that his family knows almost nothing definite about his grandfather Lawrence Waterhouse’s wartime service; even his widow and children can only agree that he “did something” (639). His grandmother is impeccably refined but helpless with practical matters, leaving men to handle everything, even secretly maintaining her Lincoln after her husband’s death.

A suitcase of photos renews Randy’s curiosity: He finds images of his grandfather in both Navy and Army uniforms, and suspects a Manila connection in 1945, possibly linked to a U-boat and a man who looks like Alan Turing.

Driving to Seattle with Amy, Randy explains his family’s nerdish obsession with precision. In a mall they meet Chester, an old gaming friend turned wealthy technologist, who invites them to his bizarre “dead tech” (651) house featuring a steam locomotive and a reconstructed TWA 747. Randy asks for an ETC card reader to decode inherited 1944-45 Arethusa intercept punch cards.

Goto Dengo confirms Bundok’s basalt is ideal for tunneling, though excavation is slow and relentless, powered by an “unlimited” (655) supply of Chinese labor working day and night under strict concealment. He begins the long, inclined shaft from the future Lake Yamamoto to Golgotha, then seals its upper opening to hide evidence while vegetation reclaims the site. To create a convincing natural lake, he builds a false dam by rolling a massive boulder into a river bottleneck, stacking additional rocks and uprooted trees, and sealing leaks with gravel, clay, and hidden tin.

Golgotha’s tunnel network is laid out to exploit elevation differences between rivers and bypass rapids. The General inspects the works, touring the concealed main drift, the true vault, and an intentionally confusing maze of false drifts designed to trap thieves, including booby-trap walls that could unleash Lake Yamamoto. Impressed, the General orders accelerated work, doubling labor to a thousand after news that Leyte has fallen. The “Decisive Battle” (662), Goto Dengo is told, is already over and Japan has lost.

Cantrell emails Randy that the Pontifex transform has been vetted by skilled cryptographers and shows no obvious weaknesses, though its steps are unusual and the author has a “strange fixation on the number 54” (663).

Randy hikes with Avi, reminiscing about their former colleague Andrew Loeb, only to learn Loeb is now a lawyer suing Epiphyte(2) via a minority-shareholder suit backed by the Dentist. The claim is that Epiphyte negligently failed to secure salvage rights from Semper Marine, costing shareholders a share of a rumored sunken-gold find. Kepler aims to convert damages into Epiphyte stock and seize control.

Randy and Avi realize the wreck’s coordinates may be recoverable through subpoenas, especially from their California server Tombstone, and fear contempt charges if encryption keys are demanded. Randy reveals the wreck holds gold bars, making the stakes existential. They suspect their systems are already being targeted when the workers at Novus Ordo Seclorum report suited men demanding access to Tombstone. Avi decides to rush there while Randy decides to do “what his conscience tells [him] to do” (675)

After the General’s visit, Goto Dengo protects Wing from Mori’s guards, knowing Wing’s leadership could fuel an escape. Wing reports the Lake Yamamoto diagonal shaft is only 50 meters from completion and wants to dig straight, but Goto insists on secret bends and orders another “ventilation shaft” (676), even though Wing hates the extra work. Filipino prisoners arrive after a brutal forced march; Goto feeds them, then selects leaders, especially Rodolfo, and quietly tells him MacArthur has landed on Leyte, reviving morale.

The Filipinos sink new shafts while the Chinese finish Golgotha. A large Japanese convoy arrives with heavy crates to be stored; every 20th crate goes to the fool’s chamber. During Christmas carols and nocturnal unloading, gunfire erupts: Soldiers massacre Filipinos at Golgotha’s entrance. A broken crate reveals gold ingots stamped “BANK OF SINGAPORE” (683) as a Filipino driver is bayoneted.

Randy leaves Avi’s house as Avi urgently evacuates his family. Seeking an untraceable Internet connection, Randy drives to Los Altos, near Ordo’s offices, where Tombstone is being threatened with seizure. He parks at a McDonald’s and climbs onto his car with a laptop, using packet radio to connect securely through laundry.org and the Crypt, then reaches Tombstone across the street.

Outside Ordo, police, lawyers, media, and Secret Admirers (a libertarian activist group) gather; several arrive openly armed, escalating tensions. Randy watches a low-bandwidth live video feed showing Avi confronting police officers and Andrew Loeb as a battering ram breaks in. Randy decides to log in as superuser “randy” (688), then quickly overwrites log files and deletes and multi-erases blocks tied to e-mails from around the salvage date.

As he launches a drive-wide overwrite script, a nearby van triggers an electromagnetic pulse that kills power and electronics across the area, blanking Randy’s screen while everyone else celebrates. Randy is unsure whether his attempt to delete all the data in time was successful.

Goto Dengo waits as smaller, frequent night convoys bring “burdens of gold” (693) into Golgotha while American air and naval fire nearby. A Mercedes arrives carrying a solid gold Buddha, which Filipino workers laboriously shove through Golgotha’s tunnels. The treasure shipments grow less organized, with bars stamped from many Asian banks, and much of it coming from Japan’s own reserves, convincing Goto Dengo that they expected defeat long ago. Escapes are attempted and crushed, and briefcases of changing radio codes arrive. A final convoy includes Nazi-labeled crates, European gold, and diamonds, likely from a German submarine.

Then Noda orders the moment of destruction: Equipment and radios are dropped into shafts, the Tojo is dammed and floods, and Mori executes prisoners at shaft mouths. Goto Dengo, claiming six prisoners for final sorting, enters the flooding tunnel, knowing it will be sealed behind him. He knows that “going forward is his chance to survive” (700).

Randy reaches the Air Kinakuta lounge after selling his EMP-fried car to a Ford dealer for $5,000, buying an expensive first-class ticket, and fearing he failed to wipe Tombstone before it was seized. He considers warning the Shaftoes to strip the wreck quickly to reduce damages that could let the Dentist take control of Epiphyte, and he imagines grabbing the jungle gold to raise the company’s value. He encounters Devorah and Avi’s family fleeing to Israel and asks her to tell Avi “zero” (703), meaning Tombstone was not fully erased.

On the plane, Randy calls Doug, but then receives an incoming call from Pontifex (root@eruditorum.org), a former NSA watcher of Randy’s grandfather. Pontifex urges him to abandon cracking Arethusa, revealing it once proved a pointless zeta-function output which was an obsession for Earl Comstock, who was largely responsible for American involvement in the Vietnam War. Though Comstock was convinced that Arethusa was a communist code, it was eventually broken to reveal the name “C-O-M-S-T-O-C-K” (708). It almost ruined Comstock’s career. Pontifex warns about dangerous future clients. Doug calls back, annoyed.

Bobby sabotages a Japanese truck by slapping “I SHALL RETURN” (710) stickers on it, then learns MacArthur has landed on Leyte. He sends a message volunteering to establish contact in Concepcion and soon receives orders to transport a radio transmitter inland. After a dangerous journey, the transmitter team is captured and executed, leaving Bobby stranded in Concepcion. He learns Glory bore his son there in 1942 and is now a famed guerrilla operative. Battling malaria, he treks south toward Manila, gathering rumors of Glory. Near Calamba, resistance contacts arrange a meeting. At dawn, Bobby is rowed toward Glory on a sandbar, only to discover her face has turned into just “the front of her skull” (716) by leprosy, shocking him into a scream before he is struck unconscious.
