Plot Summary

In October 1989, Austin Landry and three other men serve as underpaid pallbearers for Kroker Brothers Funeral Home in Grosse Tete, Louisiana. They are tasked with carrying the heavy coffin of Bernard Montcalm, a young construction worker. The coffin is cheaply made, and the graveside lowering straps are improperly secured, causing the coffin to break open after slipping into the grave. The mourners scream. A second, delayed wave of horror follows, and as Landry stares into the grave, he understands its cause.

The narrative jumps to August 1994. J. F. Foreman, owner of a discreet courier service called Expedited Medical Transport (EMT), is anxious about a new assignment: transporting a female client handcuffed to a briefcase. Reviewing security footage, Foreman saw two of his employees fraternizing, a breach of protocol that makes him paranoid about an inside job. He reassigns his newest employee, Proctor, to the main transport van and confides his suspicions, instructing Proctor to be prepared to shoot the two men if they attempt a hijack. The next morning, at his suburban home, Proctor is ambushed in his garage by a man disguised as a utility worker. Proctor awakens in a dark, padded cell. His captor, the same man, enters and lays down two rules: Proctor must not harm himself, and he must eat all the food provided. When Proctor questions him about the EMT job, the man’s confusion makes it clear that the kidnapping is unrelated. Proctor concludes that his captor has a mental illness.

Meanwhile, FBI Special Agent Dwight D. Chambers is grieving the recent death of his wife, Janice, which has left him apathetic and depressed. His eccentric new partner, Special Agent Pendergast, stages an unauthorized sting operation in their New Orleans field office, exposing a corrupt agent for attempting to sell evidence to a banker. When their superior, Special Agent in Charge Estevez, threatens to fire Pendergast, Chambers impulsively lies and claims that he authorized the operation. Estevez places the corrupt agent in custody but banishes Chambers and Pendergast from the office for a week. They decide to investigate a bizarre murder in Diamondhead, Mississippi. The victim, Kenneth Drakos, was found in a storage unit with an arm amputated after witnesses saw him fleeing a white van on a highway.

Pendergast establishes a temporary command center at his family home, Penumbra Plantation, with access to FBI databases. He theorizes that Drakos escaped not from the van, but from a nearby location in the Grand-Morte Swamp. Pendergast and Chambers visit the storage unit, which is set up as a surgical theater. There, Pendergast performs a Tibetan visualization ritual, concluding that the killer is a “seeker” whose motive is focused on the victim’s right arm. The agents find another case with the killer’s signature: a cluster of 11 pinpricks on the victim’s right shoulder. The first such case, Bernard Montcalm, was not murdered but rather killed in a construction accident. The detectives trace Montcalm’s body to Kroker Brothers Funeral Home and learn that a former technician, Parker Wickman, was fired after Montcalm’s arm went missing.

Meanwhile, Proctor remains imprisoned. After being gassed unconscious, he wakes with a hazy memory of his captor (later revealed to be Wickman) stroking his right arm with approval. This, combined with the lavish meals, convinces Proctor that Wickman is a cannibal fattening him for slaughter. Knowing that his time is short, Proctor practices breath-holding exercises from his Navy SEAL training and his time in the Ghost Company—a mysterious unit that Pendergast also served in. When Proctor is gassed again, he holds his breath and clutches a makeshift weapon he has created, hoping to attack Wickman when he enters; however, Wickman taunts him, revealing that he knows the plan. Defeated, Proctor slashes his own right arm to thwart Wickman, who leaves him to bleed to death.

Wickman, who has previously been in touch with a man named Dr. Telligren about an unspecified operation that cannot be postponed, abducts a man named Jake from a gym to serve as an alternate “resource.” That evening, Telligren and another doctor, Magnus, arrive at Wickman’s home; when Wickman reminds them of his leverage over them, they reluctantly sign an agreement acknowledging their responsibility for his current state and promising to see him through his recovery. They then place Wickman under anesthesia.

Meanwhile, Pendergast connects the name Wickman to the “Wichman House” on old maps of the swamp. When he and Chambers go to investigate, they see smoke rising from the location and rush in. Outside, they find two bodies in the water, each missing a right arm: Wickman and Jake. Inside the burning mansion, they discover a surgical suite, a lab with victims’ tissue samples, and a chapel with an inverted-V candelabrum that matches the pinprick signature. They rescue a wounded Proctor from a sub-basement cell just before the house collapses.

At the scene the next morning, Pendergast defies Estevez’s orders and collects evidence from the ruins, coercing his superior into letting him and Chambers stay on the case. Chambers believes that Wickman was killed in an act of revenge, but Pendergast insists that they investigate Wickman’s past. They agree to a three-day compromise in which Pendergast can pursue this theory. The investigation shows that Wickman was a well-adjusted young man until he entered a parapsychology (PSI) graduate program at Tulane University, after which his personality changed dramatically.

At Tulane, the agents discover that all records of the PSI program have been erased. They interview Dr. Telligren, a key faculty member, and meet his arrogant colleague, Dr. Dorion Magnus, a former classmate of Wickman’s. However, after three days yield no proof, Chambers declares the investigation a failure and decides to end his partnership with Pendergast. While Chambers pursues a revenge-killing lead that proves doubtful, Pendergast steals the missing Tulane course catalogs, which reveal a secret program run by Telligren involving surgical experiments to enhance PSI abilities in student volunteers. That night, Magnus murders Telligren to silence him. At the scene the following morning, Pendergast confronts Magnus and takes a crossword puzzle that he believes contains a taunting message. At a tense dinner, Pendergast presents his theory that Magnus killed Telligren, using the crossword as evidence. He further argues that Wickman developed body integrity disorder as a result of the PSI experiments and hoped to have his arm surgically replaced; he coerced Magnus and Telligren into going along with this project, but they ultimately killed him. However, Chambers views Pendergast’s claims as absurd.

Pendergast asks to interview Magnus, who agrees, inviting him to his restored steamboat, the Fantôme. However, Magnus then calls Chambers, asking that he attend as well, citing concerns about his own safety. On the boat, Magnus first accuses Pendergast of murdering Telligren. He then reads Chambers’s mind and confesses to poisoning his coffee that morning with a nerve agent. Chambers dies, and Magnus disarms Pendergast and has him locked in the ship’s hold as the Fantôme heads into the remote Mississippi Delta.

Pendergast escapes, arms himself with tools and chemicals, and systematically eliminates the crew. He sets the ship ablaze and discovers a secret, opulent room that is part boudoir, part morgue. A gunfight between Pendergast and Magnus ensues on the decks of the burning, sinking ship. Pendergast uses a Tibetan visualization discipline to project a false mental image, tricking Magnus’s telepathy and then throwing him into the boat’s paddle wheel. After they both swim to shore, the badly injured Magnus hints at a similar secret room in his mansion before dying by suicide.

Pendergast infiltrates Magnus’s mansion during the FBI search and discovers the hidden room. Inside is a scene of necrophilia: the preserved corpse of a young woman showing signs of repeated violation. Horrified, Pendergast alerts Estevez. In the aftermath, Chambers is posthumously hailed as a hero. Estevez, wanting the troublesome Pendergast out of his office, arranges for his transfer. Pendergast visits Proctor in the hospital and offers him a job as his driver and assistant, which Proctor accepts.

Seven months later, Pendergast is called to a gruesome crime scene at the New York Museum of Natural History: a man’s brain has been violently removed, and there appear to be claw marks on a metal door. He and the local police detective agree to work the case together.
