Nate Hallinger

Nate Hallinger is a detective newly assigned to the Charleston division whose investigation of the attacks on Kate MacKenna places him in close contact with Dylan Buchanan and the MacKenna family. He first appears as an alert investigator at a crime scene; later, his work on the bombings and the people around Kate seems to make him an important ally. That apparent role reverses when the investigation reveals that he has been helping Roger MacKenna and has received information from Vanessa MacKenna. His character arc turns on that contrast between professional access and concealed complicity.

Identity and First Appearance

Nate’s introduction is shaped by attention to small details. As the crime-scene team works across the area, he hears a cell phone ringing near an uprooted walnut tree. The tune recalls a Harry Potter film he had taken his nephews to see. By the time he reaches the tree, the ringing has stopped; searching beneath a branch, he is the first to spot a woman’s legs. The scene establishes both his newness to the Charleston assignment and his proximity to a discovery that begins the investigation. His attention is initially directed toward the evidence, not toward any personal connection to the people involved.

He also makes himself available to Kate. After meeting her, he realizes that he has forgotten to give her his card and supplies it, asking her to call if she needs anything or remembers even a detail she considers insignificant. The gesture is presented as ordinary investigative courtesy, but it establishes a direct channel between detective and potential witness. In retrospect, that accessibility sits uneasily beside the later revelation that Nate is not simply a reliable point of contact for the investigation.

Investigative Work and Cooperation

Nate’s work spans several connected lines of inquiry. In discussing the explosion at the Liongate event, he explains that investigators can often trace an explosion to its origin and identifies the basket of flowers on the ground in front of a table near the back of the tent. It was Kate’s table. The location matters because it ties the device to a place associated with her, rather than leaving the bombing as an indiscriminate attack. Nate helps articulate how physical placement can turn a crime scene into evidence about its intended target.

The connection between the Charleston investigation and the later warehouse attack emerges through local cooperation. Dylan tells Kate that a Silver Springs firefighter recognized similarities between the incidents and contacted the Charleston Police Department to learn who was leading the Charleston case. That call allowed Nate to find out that Kate was at the warehouse. The chain of communication shows the value of coordination across jurisdictions, while also making clear how information about Kate’s movements could travel among people involved in the response.

Nate checks Carl Bertolli’s account of his whereabouts by speaking with the limousine driver, who confirms the time Carl gave. He says he will speak with Carl again after the Federal Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms and Explosives finish questioning him. This is a concrete example of Nate following up on a possible lead without treating suspicion as proof. It also places his investigation alongside that of federal agents, with responsibilities overlapping as they pursue the bombing and its connections.

His professional relationship with Dylan is similarly cooperative on the surface. Nate waits anxiously for Dylan to call and, when he answers, quickly tells him what he has learned about the MacKenna brothers. Later, Nate discusses jurisdiction with Dylan: Dylan can be on loan from the Boston Police Department, but he will work under Chief Drummond’s command in Charleston. These exchanges present Nate as someone who shares information and understands that the investigation must operate within local authority, even as the later plot recasts that apparent partnership.

Workload, Ambition, and Access

Dylan describes Nate as overworked, not unwilling. According to Dylan, Nate is tracking Jackman, keeping watch on Roger and the two brothers, and trying to manage competing investigative demands. The Federal Bureau of Investigation is concentrating on the bomber, while federal agents are also searching for Jackman; the overlapping efforts have made the work disorganized. Dylan believes Nate wants to prove himself in his new department, and that bringing Jackman in would look good on his record. He therefore tries to take some of the load off Nate’s shoulders.

That account gives Nate a plausible professional ambition, but it also makes his position consequential. He has access to several strands of the inquiry: the bombing, Roger’s activities, the brothers, and the search for Jackman. Dylan’s concern that Nate is carrying too much work encourages trust and cooperation. In the later revelation, the same access has a darker significance: knowledge of people, schedules, and investigative movements can serve the person entrusted to pursue a case as well as the investigation itself.

Nate also appears at Kate’s home when she expects Chief Drummond to arrive with dinner. His unexpected visit briefly shifts the scene from ordinary support to surprise, although the available account does not specify the purpose of that visit. Taken together with his offer of a card and his ongoing calls with Dylan, the encounter reinforces how readily he is able to enter the circle around Kate while the attacks are still being investigated.

Roger’s Plans and the Exposure of Nate

When Nate announces that the case is over, he identifies Roger as the central suspect. Having seen a video, he says he had already considered Roger the leading suspect and had requested a search warrant; with the new proof, he says the warrant is no longer needed. He also recognizes that Roger had help. The announcement initially casts Nate as the investigator who has brought the case to a decisive point, and his excitement suggests confidence in the conclusion.

Nate’s account of the evidence includes a calendar found in the kitchen beside a phone. Investigators have collected it because it bears many fingerprints, and Nate notes that it contains two distinct handwritings rather than Roger’s alone. He has sent it to the laboratory on an urgent basis. Along with times and places, the calendar contains Kate’s flight numbers, showing that someone knew when she was travelling to Boston and when she would return. These details link the planning to knowledge of Kate’s movements and support the suspicion that Roger did not act alone.

The investigation’s apparent success becomes a turning point when Nate’s own knowledge is examined. During the confrontation, Dylan argues that Nate was involved in a plan to kill Kate and make it appear that Ewan MacKenna had shot her, with Nate positioned as the person who would stop Ewan. Dylan also connects the plot to the inheritance: Vanessa had filmed Compton MacKenna’s video, in which Compton left most of his estate to Kate, and the will had already been changed. The proposed motive was the large inheritance, not merely the attacks considered as separate crimes.

A specific piece of information exposes the link between Nate and Vanessa. Dylan recalls that Nate knew Kate had initially turned down the inheritance, even though Vanessa had left before Kate changed her mind and accepted it. Dylan concludes that Nate could have learned this from Vanessa. The deduction turns what might have looked like a well-informed investigator’s observation into evidence of a private channel between the conspirators. Nate’s work beside Dylan and his apparent concern for the case are consequently reinterpreted as a cover for access and assistance.

Narrative Role

Nate’s arc is built from a reversal in the meaning of investigative competence. His early acts—finding a clue at the crime scene, checking Carl’s account, sharing developments with Dylan, and organizing evidence—encourage the reader to regard him as part of the machinery protecting Kate. The calendar’s two handwritings, Roger’s need for help, and Nate’s unexplained knowledge of Kate’s inheritance decision gradually undermine that trust. His betrayal is made legible through evidence already connected to the investigation: schedules, access, and the movement of information between people.

The contrast is especially sharp because Nate is not introduced as an outsider forcing his way into the case. He is newly assigned, eager to establish himself, and sufficiently trusted that Dylan worries about his workload and offers assistance. Those circumstances make the eventual accusation more than a revelation of criminal involvement: they show how a position created to investigate danger can also provide the means to participate in it. Nate’s role therefore joins the book’s procedural clues to its central problem of trust—who knows Kate’s movements, who can act on that knowledge, and whether apparent protection can conceal a threat.
