Relic (1995) is a techno-thriller by writing duo Douglas Preston and Lincoln Child. The novel introduces FBI Special Agent Pendergast, the protagonist of a long-running and popular series. In the days leading up to a major gala celebrating the new Superstition exhibition at the New York Museum of Natural History, a series of savage murders occurs within the museum’s halls. When autopsies suggest that the killer may not be human, a graduate student named Margo Green joins Pendergast’s investigation to uncover the truth, which is connected to a mysterious artifact recovered from anthropologist John Whittlesey’s doomed Amazon expedition. The novel explores concepts such as Institutional Prestige as a Veil for Dangerous Truths, The Fragile Illusion of Civilized Behavior, and Scientific Inquiry as a Counterpart to Horror.

The novel’s richly detailed and claustrophobic setting is heavily informed by co-author Douglas Preston’s work at the American Museum of Natural History from 1978 to 1985, where he was a writer and editor with access to the non-public collection vaults and corridors that feature prominently in the story. Relic was the first collaboration between Douglas Preston and Lincoln Child, as Child served as Preston’s editor for his nonfiction book about the museum, Dinosaurs in the Attic (1986). The novel was a commercial success and launched the Pendergast series, which has since grown to include more than 20 books. A largely inaccurate film adaptation titled The Relic was released in 1997, though it notably omits the character of Agent Pendergast.

Plot Summary

The first novel in the Pendergast series opens in the Amazon Basin in 1987, where anthropologist John Whittlesey discovers a figurine of a beast called Mbwun. Convinced it proves the existence of the mysterious Kothoga tribe, he sends his assistant Carlos back to civilization with a crate of artifacts before pressing deeper into the jungle to find his missing colleague, Crocker. Whittlesey discovers Crocker’s mutilated, decapitated corpse and glimpses fiery eyes in the brush as something massive moves toward him. Nearly a year later, in a dockside warehouse in Belém, Brazil, a smuggler named Ven is killed by an unseen attacker lurking behind Whittlesey’s museum crates, which are awaiting shipment to New York.

Years later, the New York Museum of Natural History is rocked by the discovery of two murdered boys in its basement. Margo Green, a graduate student in ethnopharmacology who is working under Dr. Frock’s mentorship, arrives to find the museum swarming with police. Lieutenant Vincent D’Agosta of the NYPD announces a lockdown while officers sweep the building. Journalist Bill Smithback, who is commissioned to write a book about the museum’s upcoming Superstition exhibition, tells Margo the boys were savagely killed, and rumors of a wild animal circulate. Museum Director Winston Wright holds a frantic press conference insisting the exhibition opening will proceed on schedule.

Margo has a meeting with Frock, a scientist who uses a wheelchair and is known for his Callisto Effect theory, which posits that evolution sometimes produces sudden monstrous species. In light of the murders, Frock notes that the force used on the bodies was abnormal. Margo also meets with George Moriarty, the young curator of the Superstition exhibition, who reveals that one of the exhibits, the Kothoga figurine of the monstrous Mbwun, has been fraught with high-level controversy; the expedition crates that contained the figurine were recently moved to the museum’s secure area after someone tampered with them.

When a night guard named Fred Jolley is found disemboweled and decapitated and his brain extracted, FBI Special Agent Pendergast arrives from the New Orleans field office. Pendergast connects the museum killings to unsolved murders in Louisiana. He and D’Agosta find blood trails and deep, three-pronged claw marks in the museum. An autopsy confirms that the killer removes the hypothalamus, a brain region that regulates hormones. A claw fragment is embedded in one victim’s chest, and a DNA analysis yields partial matches to both human and gecko genes.

Pendergast negotiates Wright’s cooperation by threatening to close the museum, then consults Frock, who identifies the claw’s structure as dinosaurian. Deputy Director Ian Cuthbert explains the Whittlesey expedition’s history: Whittlesey and Crocker disappeared, the rest of the party died in a plane crash, and one crate had been broken into with only some seed pods missing, while the valuable Mbwun figurine remained. Frock observes that the crate’s boards are scored on the inside as well as the outside, implying that something broke out of it.

Margo sneaks into the sealed exhibition and sees the Mbwun figurine, a scaled creature crouching on all fours with three claws on each forelimb, matching the victims’ wounds. A stealthy presence stalks her through the darkened galleries before she flees in terror. Later, she, Smithback, and Moriarty begin connecting the expedition to the killings. Smithback discovers that the freighter carrying the Whittlesey crates was found beached near New Orleans with its entire crew slain by identical wounds. The killings have followed the crates from the Amazon.

Moriarty discovers that Lavinia Rickman, the museum’s chief of public relations, removed Whittlesey’s journal from the crates and that the record was deliberately deleted. Smithback steals the journal from Rickman’s desk. It describes the expedition’s final days, including an encounter with an old woman who warned about the dangers of Mbwun. A retired botanist who knew Whittlesey provides crucial background, explaining that a young researcher named Montague was assigned to curate the crates but vanished without explanation. He also says that the tepui near which the expedition found its specimens was later destroyed by napalm and mining.

Working in the genetics lab, Margo sequences DNA from the crate’s packing fibers and learns that the fibers come from a plant heavily infected with an ancient reovirus produces human hypothalamus hormones. She and Frock deduce that the creature depends on these hormones; when the crates were locked in the secure area, cutting off its supply, it began killing humans and consuming their brains as a substitute. Using Assistant Curator Gregory Kawakita’s genetic sequence extrapolator, they generate a genetic profile of the beast: a quadruped weighing over 500 pounds with near-human intelligence, extreme speed, poor eyesight, and nocturnal habits.

The opening night party proceeds despite their warnings, with 5,000 guests. The incompetent Special Agent Spencer Coffey of the New York FBI field office has recently taken over Pendergast’s investigation, responding to political pressure from the governor’s office. He has overridden Pendergast’s security recommendations, sealing all but one emergency exit and relying on an untested computerized system. When Officer Beauregard’s days-old corpse is discovered atop a display case, a stampede erupts amid a sudden, complete failure of the security system, which traps everyone inside with heavy steel doors.

The creature attacks the trapped guests, killing several people. D’Agosta drives it back with shotgun fire and leads the survivors into the flooded subbasement, guided by Pendergast’s radio directions. Wright, Cuthbert, and Rickman flee upstairs; the creature follows and kills Wright. A SWAT team breaching through the roof is decimated in the Hall of Cretaceous Dinosaurs.

Pendergast and Margo use themselves as bait and as the creature charges, Margo realizes that the creature’s forward-facing primate eyes offer a direct path to the brain. Pendergast fires his last round through its eye, killing it instantly.

Deep in the subbasement, D’Agosta’s group reaches a dead-end tunnel and rides the rising floodwater to grab a ladder near the ceiling. They climb through a lair filled with animal and human remains before escaping through a manhole to a New York street.

Four weeks later, the survivors gather in Frock’s office. The creature’s corpse has been seized by the government. Wright and Rickman are dead, and Cuthbert is in a mental hospital. The creature’s lair yielded the remains of Montague, the researcher who vanished years earlier. D’Agosta has been promoted to captain, Smithback has secured a book contract, and Margo has decided to stay and finish her dissertation.

In an Epilogue set six months later, Kawakita has secretly cultivated the extinct plant and has discovered the truth no one else grasped. The creature was Whittlesey himself, transformed by the virus after the Kothoga force-fed him the plant. Kawakita has begun selling the plant’s narcotic byproduct, a drug called “glaze,” while engineering the virus for his own purposes, convinced that he can control what the Kothoga could not.
