Summary

Liz Dutton picks up Jamie from school and drives him to Central Park. On the way, she explains the long history of the serial bomber Thumper, who set nineteen bombs between 1996 and 2009 before killing his first victim in 2009. After that, Thumper escalated, setting ten more bombs over the next four years and killing three more people. He was finally caught when a building superintendent discovered a bundle of wires, a blasting cap, and a scrap of paper printed with “CANACO” (a Canadian dynamite manufacturer) in a trash spill. Police identified the tenant Kenneth Alan Therriault, who had dual U.S./Canadian citizenship and construction experience in Canada. They found an IBM Selectric typewriter in his apartment matching the fonts used in Thumper’s notes. The super’s gossip allowed Therriault to flee, but he later went to Central Park and shot himself on a bench. Liz asks Jamie to see if Thumper’s ghost is present, but Jamie sees nothing. She then reveals a suicide note pinned to Therriault’s shirt, which claimed there was one more bomb, “a big one,” and dared the police to find it.

Key Events

  • Liz picks Jamie up from school and drives to Central Park.
  • She recounts Thumper’s bombing spree from 1996 to 2013, including the escalation after the first murder.
  • The break in the case comes from a building super who finds bomb-making materials and a CANACO paper scrap.
  • Police identify Kenneth Therriault via tenant screening and dual citizenship.
  • They find his apartment and the typewriter, but Therriault has fled.
  • Therriault commits suicide in Central Park with a Ruger .45.
  • Jamie is unable to see Therriault’s ghost.
  • Liz reveals Thumper’s suicide note warning of one more bomb.

Character Development

  • Jamie Conklin – Jamie grows more aware of the danger he is being pulled into. He feels “kidnapped” like Ramona Sheinberg, showing his vulnerability and reluctance. His inability to see Thumper raises doubts about his powers or the reliability of ghosts.
  • Liz Dutton – Liz is revealed to be less central to the Thumper case than she claimed. She was not part of the current task force; Internal Affairs is circling her. Her desperation for a “miracle” reveals her manipulative side and the personal stakes driving her actions.
  • Kenneth Therriault (Thumper) – Though dead, his backstory shows a methodical, long-running terrorist who enjoyed taunting police. His suicide note suggests a final act of defiance.

Themes, Symbols, or Motifs Evidenced Here

  • Appearance vs. Reality – Liz pretends to be a key investigator, but in truth she is on the outs with the NYPD. Jamie’s power seems to fail (or the ghost simply isn’t there), challenging the reliability of the supernatural.
  • The Weight of the Past – Thumper’s long bombing history and the accumulated deaths haunt the present. The unresolved final bomb represents the lingering danger of unfinished business.
  • Unseen Threats – Both the ghost Jamie cannot see and the hidden final bomb underscore the theme that not all dangers are visible.
  • Trust and Manipulation – Liz uses Jamie as a tool, not a partner. The chapter deepens the ethical questions around using a child’s supernatural ability for police work.

Why This Chapter Matters

This chapter serves as a major turning point. It introduces the final remaining bomb, raising the story’s stakes for the climax. It also exposes the cracks in Liz’s credibility and Jamie’s growing disillusionment. The suicide of Thumper removes the living villain but leaves a ghostly trace—or the absence of one—that Jamie must interpret. The chapter shifts the focus from catching a bomber to preventing a disaster, relying on Jamie’s ability to see the dead if Thumper’s ghost appears.

Study Questions and Answers

1. Why does Jamie fail to see Thumper’s ghost in Central Park?
Answer: Jamie sees ghosts only in places where the dead spent significant time while alive, or where they experienced strong emotions. Thumper’s suicide spot may not be a lingering place for him; he died instantly and may have moved on. Alternatively, the ghost could be elsewhere (his apartment or workplace). Jamie’s failure suggests his power has limits.

2. How does Liz’s true status within the NYPD change the reader’s understanding of her actions?
Answer: Liz is not a member of the current Thumper task force; Internal Affairs is investigating her. She needs a high-profile success to salvage her career. This explains why she involves Jamie—he is her last resort. Her claims of “we” are exaggerations, and she is willing to manipulate a child to get results.

3. What is the significance of Thumper’s final note, and how does it affect the plot going forward?
Answer: The note claims there is one more bomb, “a big one,” and is signed THUMPER. It raises the stakes from a closed case to an active threat. Jamie’s ability to see ghosts may be the only way to locate the hidden bomb if Thumper’s ghost reveals its location. This sets up the climax where Jamie must confront the dead bomber.
