Dublin serves as the novel’s urban center: a place of police work and political institutions, but also a destination imagined by children seeking escape and a setting through which the investigation moves. Its significance comes from these overlapping uses. The city is at once a lived environment of offices, roads, and shops and a point of reference connecting personal histories to wider questions of development and power.

Suburban beginnings and urban aspiration

The opening account places Dublin within reach of a new housing estate on a hill. The estate is described as an orderly maze of recently built semi-detached houses, initially surrounded by a rough two-track path. Young families arrive from poorer urban conditions, including tenements and outdoor toilets, or in pursuit of gardens and streets where their children can play. Their move outward is presented as a practical fresh start, shaped by what a teacher’s or bus driver’s salary could afford. Dublin is therefore not only a city at the center of the story but also the point from which families seek homes and a different kind of life on its edge.

That suburban growth is also associated with official promises about solving overcrowding and other urban problems. The narrator’s account sets those grand claims beside the modest, still-unfinished reality of the new estate. Later, the proposed motorway makes development around Knocknaree a subject of suspicion: in 2000, journalist Michael Kiely wrote that the plan seemed already to have benefited property developers. The city’s outward expansion and the interests attached to it form a connection between Dublin’s urban future and the investigation’s concerns about land and influence. The evidence presents that connection through Kiely’s account and the proposed road, rather than establishing the allegations he was prevented from pursuing as proven facts.

Police work and the city’s institutions

The narrator’s professional life is anchored in Dublin. He says he is from the city, though his accent came from attending boarding school in England. His route into detective work took him through Templemore and police training before he joined the Murder squad. He recalls being drawn not to the mystery of his own childhood, but to the squad’s specialized language, clothing, and methods. This makes Dublin the setting of an adult identity built around investigative work, even as the narrator’s earlier life remains difficult for him to remember clearly.

The squad works from the grounds of Dublin Castle. Its interiors have been refurbished as conventional offices, while the exterior retains old brick and marble, battlements, turrets, carvings, and cobblestones. The contrast brings together the ordinary administration of modern police work and the imposing history of the buildings around it. The narrator also describes a basement of flagstones, columns, and low arches, formerly a wine cellar, where old case files are kept. These rooms place the investigation inside a city institution whose historic fabric survives beneath standardized office routines.

Dublin’s police geography includes Harcourt Street as well as Dublin Castle. After the case is closed, the narrator is assigned to the main detective unit in Harcourt Street while verdicts are pending. He remains officially attached to the Murder squad, but his new position is uncertain: he is given a desk, sometimes receives paperwork, and otherwise wanders the corridors. The move changes his working life without resolving his institutional status. Dublin’s offices thus register both the organization of police work and the consequences of the narrator’s conduct during the investigation.

Investigation across the city

The investigation repeatedly turns to Dublin’s records and institutions to pursue the past. Seeking information about a woman who may have lived near Knocknaree in 1984, the narrator contacts the census bureau, while Cassie Maddox tries to obtain the Dublin South-West electoral register for 1988. Both efforts meet bureaucratic obstacles; the narrator is told that census information requires a court order, and the electoral-register inquiry encounters similar delays. Their searches make the city a place where official traces might help identify someone, but where access to those traces is not immediate or assured.

Dublin is also the location from which the team conducts its regular work. Two and a half weeks into the investigation, O'Kelly calls Rob Ryan, Cassie Maddox, and Sam O'Neill from the incident room into his office. The busy room, with Sam making calls and Cassie using a computer, becomes the setting for a decisive meeting. The episode situates the investigation within the daily rhythms of the city’s police operation: calls, paperwork, coffee, and colleagues’ watchful attention accompany the case’s turning points.

The city’s wider political and journalistic networks surface through Sam’s meeting with Michael Kiely. Kiely, a semi-retired journalist, had written about the motorway plan and the developers who might benefit from it. He agrees to meet Sam only after hesitation, choosing a pub on the far side of Phoenix Park rather than a place in town. There, he explains that he had been taken off the story soon after beginning it, officially for legal reasons and lack of proof, though he believed the decision was personal. His account gives the investigation a lead into the history of the development debate, while also showing how a story about Dublin-area interests could be constrained before it was fully pursued.

Routes, memory, and the city as destination

Dublin appears in the children’s plans as a place to reach when home feels restrictive. In a remembered conversation, the narrator proposes that he and Jamie hide for a few weeks, then go to Dublin to get Jamie out of boarding school. The plan is improvised and uncertain, but the city gives their imagined escape a direction and a practical objective. This remembered use of Dublin differs from the institutional city of police stations and records: to the children, it is somewhere they might go to alter the circumstances imposed on them.

For Sam O'Neill, Dublin is bound to a family memory of political achievement. He recalls being taken there as a very young child when his uncle Red entered the Dáil. Wearing a new suit, he watched the family gather and saw his father’s pride; the moment remained preserved in a photograph on the sitting-room wall. The memory gives the city a personal and ceremonial meaning, linking Sam’s loyalty to his uncle with a formative image of public recognition. That earlier attachment matters when Sam later confronts information about his uncle’s conduct.

The city also appears through the narrator’s ordinary movements. On a bright day he finds an unusually convenient parking space on Stephen’s Green, shops in a bookshop off Grafton Street, and buys a cappuccino machine at Brown Thomas as a belated present for Cassie. These details place the investigation alongside errands, workplace relationships, and plans for a gift. Elsewhere, a flat tire on Merrion Road delays the narrator on his way to work, bringing the city’s traffic and practical disruptions into the account of his strained return to the office. Together, such episodes make Dublin more than a backdrop: it is the connected urban space through which professional duty, friendship, family history, political ambition, and the pursuit of evidence repeatedly pass.
