Chapter Summary

Letty Davenport is nearly a hundred miles from Taos when she calls Greet to report that Callister is dead. Greet immediately arranges for the Santa Fe airport to be covered and diverts the Fort Detrick team on its way to Lamy back to the airport. Greet then delivers unsettling news: the Fort Detrick researchers believe the reconstructed virus is viable—it combines the infectiousness of measles with the full lethality of a Marburg particle. A usable vaccine would require approval from multiple CDC committees, a process too slow to help if Scott or Catton release the virus. The Army has mobilized the 93rd Military Police Battalion from Fort Bliss, initially planning to stage at Kirtland Air Force Base, but Greet orders them straight into Taos to blockade the town. Letty tells Greet that word has leaked that Scott’s people are trying to spread a killer virus, further raising the stakes.

At the Santa Fe airport, Dyer and Rocha, the two Fort Detrick scientists, suit up and carefully extract five intact vials from Callister’s fanny pack. They seal the vials in a steel lockbox. After a debate over disposal—Rocha suggests burning the body with gasoline—Letty vetoes that idea. A local police officer, Martha, uses a Kubota track loader to bury the body under three feet of dirt. Letty records a statement accepting responsibility for the shooting. The airport manager protests that an American Airlines plane is due, but Letty dismisses his concerns.

The team travels to Lamy, where Jerry Wright has been guarding a possible grave site. Dyer and Rocha dig down two feet and hit plastic. They expand the hole, exposing a long plastic-wrapped bundle that clearly contains a body. They suit up, lift the bundle, and take tissue samples from multiple organs, resealing each cut with antiviral tape. The samples are labeled and stored for transport to Fort Detrick. After repacking the body in the grave and covering it, the scientists are hosed down with antiviral solution. The chapter ends with the team preparing to return to Taos, leaving Wright to guard the site until a permanent solution is arranged.

Key Events

  • Letty informs Greet of Callister’s death; Greet coordinates airport security and diverts the Detrick team.
  • Greet reveals the reconstructed virus is viable and vaccine approval will be slow.
  • The Army sends MPs toward Taos; Greet orders an immediate blockade.
  • Dyer and Rocha recover five intact virus vials from Callister’s fanny pack.
  • A police officer, Martha, buries Callister’s body under deep dirt after Letty rejects burning it.
  • The team exhumes a plastic-wrapped body at Lamy, takes tissue samples, and reburies it.
  • The scientists express concern about potential unauthorized use of the virus.

Character Development

Letty Davenport continues to operate under immense pressure, balancing tactical decisions with ethical boundaries. She rejects the suggestion to burn Callister’s body but accepts a practical burial. Her frustration with the airport manager shows her stress level rising. She also takes formal responsibility for the shooting.

Greet demonstrates ruthless efficiency: she overrides the Army’s staging plan, orders an immediate blockade, and shares classified information with Letty about the need to obscure blame. Her readiness to sacrifice due process for speed highlights her pragmatic, ends-justify-the-means approach.

Dyer and Rocha are meticulous scientists who follow strict antiviral protocols. They are also unafraid to voice dark thoughts—Rocha speculates that someone might weaponize the virus after developing a vaccine, and Dyer warns against discussing it if they want to keep their jobs. This adds a layer of moral ambiguity to the scientific team.

Jerry Wright is shown dutifully guarding the grave site. Cartwright engages in light flirtation with Wright, revealing a more playful side amid the tension.

Themes, Symbols & Motifs

Bureaucratic friction vs. urgent threat – Greet’s frustration with the CDC’s slow approval process and the Army’s initial staging plan underscores how institutional delays can jeopardize a rapid response to a bioweapon threat.

Bioethics and disposal – The debate over whether to burn or bury Callister’s body reflects the larger challenge of handling hazardous remains in the field. Letty’s refusal to burn the body shows her commitment to humane treatment even of an enemy.

Secrecy and trust – Greet confides in Letty about the need to “obscure exactly what happened” to protect higher officials. The scientists hint that the virus could be diverted for offensive use. Trust between team members remains fragile.

The earth as containment – Burying the body under dirt (and later reburying the Lamy victim) symbolizes a crude but effective quarantine. The repeated use of antiviral spray and sealed suits reinforces the theme of preventing contamination.

Why This Chapter Matters

Chapter 20 solidifies the stakes: the virus is confirmed as a real, viable weapon, and the team learns that their adversary’s plans may already be known to the public. The chapter shifts the action from the immediate threat of one carrier (Callister) to the broader search for Scott and Catton. It also deepens the world-building around the scientific and logistical response to a biological attack, showing how military, law enforcement, and research arms coordinate (and occasionally clash). The chilling hint that the virus could be turned into an offensive weapon adds a layer of moral complexity that will likely echo in later chapters.

Study Questions & Answers

1. Why does Letty reject the suggestion to burn Callister’s body?
Letty finds the idea of dousing the body in gasoline and burning it appalling, even though Callister is dead. She prefers a dirt burial, which also preserves the body for later testing to see if the carriers were contaminating themselves.

2. What does Greet’s decision to order the MPs directly into Taos reveal about her leadership style?
Greet overrides the Army’s plan to stage at Kirtland Air Force Base and orders an immediate blockade. This shows she values speed over protocol and is willing to bypass chain-of-command to prevent a catastrophic release of the virus.

3. What dark possibility do Rocha and Dyer discuss after the Lamy exhumation?
Rocha speculates that someone could develop an effective vaccine, stockpile it, and then deliberately release the virus in a foreign country to solve “problems” under the guise of a natural outbreak. Dyer warns that discussing such ideas could cost them their jobs.
