Manchester is the central urban setting of the investigation: the place where a suspicious death brings Jo into the case, where Operation Alecto takes shape as a shared inquiry, and where police work must contend with evidence gaps, competing demands and the consequences of a death during an operation. The narrative gives the city more than a backdrop function. Its hospitals, roads, specialist police facilities and surrounding workplaces form a working geography through which investigators pursue leads and exercise authority.

Urban setting and police infrastructure

Jo is directed to Manchester Royal Infirmary to assist Greater Manchester Police with a suspicious death in the Critical Care Unit. The assignment begins without the rest of her usual team: Max has been assigned to an operation concerning an apparent organised honour-killing syndicate, and Jo is told she will work alone, though National Crime Agency resources remain available. Manchester therefore enters the plot as a place of urgent police business and divided institutional attention.

The city’s investigative infrastructure is concentrated at Nexus House, a brick-and-glass office building on an industrial estate only yards from the M60 motorway. Its unremarkable exterior conceals several specialist Greater Manchester Police units: the Serious Crime Division, the Economic Crime Unit and the Cold Case Unit, alongside Forensic Services. The latter promises, in theory, a faster turnaround for crime-scene samples. Opened less than two years earlier, Nexus House was already part of Jo’s professional world: it opened a fortnight after her secondment to the National Crime Agency began. The contrast between ordinary office-block appearance and the specialist work inside makes the building a practical hub for the city’s investigations.

Investigation across the city

Manchester’s police work is presented as a sequence of concrete procedures rather than a single breakthrough. At Nexus House, Jo consults a laminated digest of the Murder Investigation Manual, a compact set of checklists and diagrams covering investigative strategy. She uses it to review the main elements a review team must consider after the Fast Track menu, and to check that the inquiry has not overlooked essential steps. The manual makes procedure visible as a tool for organizing a complex investigation, not merely an administrative formality.

Jo also sets out how the team will share information. She asks for an update from the crime scene to be shown to everyone rather than relayed privately through her, so members in different roles can hear the same material and raise questions. Her stated principle is equal access: a missing piece may be noticed by any member of the team, and she includes herself in the ban on prima donnas. The team responds with approval. In this account of police work in Manchester, the city’s institutional setting is also where Jo defines an investigative culture based on collective scrutiny.

When senior officials ask about progress, Jo distinguishes evidence from unresolved possibility. The team has compiled an exhaustive list of people who might hold a grudge against either victim, but no name appears on both lists. Investigators have partial boot prints and a piece of fabric from the Manchester crime scene, as well as hours of passive media, principally from fixed-speed and automatic number-plate-recognition cameras. All three strands of work are proceeding, but there is no suspect yet. The unusual presence of ricin prompts questions from the Mayor, but the inquiry has not established that it will identify the perpetrator. Manchester is thus rendered as a dense field of potential information that still has to be tested rather than a place where the answer is immediately legible.

The city’s reach extends into nearby settings and working lives. A witness describes walking in a park before driving to Northenden to collect her granddaughter, taking the child to school on Beaver Road, and then returning to collect a poster urgently needed by her daughter. The errand takes her to the Department of Chemistry at Manchester University, where her daughter is waiting on Brunswick Street. This detailed route supplies investigators with a sequence of ordinary movements and locations to examine; its value lies in the specificity of an everyday itinerary, not in any immediate conclusion about it.

Roads, institutions and criminal pressure

The M60 motorway helps situate Nexus House, but Manchester’s roads also impose delays on police work. After investigators check an alibi at stables, Jo and Carly set off back to the city at 6:45 p.m. Bad weather has caused multiple accidents, and the resulting backlog has extended into rush hour, leaving them with a slow, stop-start journey. The delay gives Carly time to question why Jo did not take a rifle for forensic comparison with two recovered pellets. Jo explains that they had no warrant, that she could have asked for voluntary access, and that a pellet’s small contact area makes a court-worthy match difficult to establish. She would have returned for the rifle if the alibi had failed. The exchange shows how travel time, legal authority and limits of forensic comparison all bear on decisions made in the Manchester investigation.

The city is also associated with a struggle over the criminal power left behind by the case. Nick reports that O’Neill’s mob may be seeking to fill the vacuum, with O’Neill directing matters at arm’s length. Carly recognizes that rival gangs could also want a share, but Gordon cautions the team against settling prematurely on a motive: O’Neill, he says, will have made many enemies. As the police car passes Longsight Police Station, Gordon recalls it as the place where his career in the unit began. Manchester’s streets consequently hold both the present uncertainty of the inquiry and the professional histories through which its investigators understand local criminal rivalries.

Command, accountability and aftermath

Police command in Manchester places Jo before senior civic and police figures. At Greater Manchester Police Headquarters, she attends a fourth-floor meeting with Chief Constable Robert Hampson, the Mayor of Greater Manchester, Charlotte Mason, and Assistant Commissioner Helen Gates. Their position at the table and Jo’s seat opposite make the meeting feel to her like an interview or interrogation. She arrives late after traffic slows behind a broken-down tanker in roadworks and apologizes. The encounter frames the investigation as answerable not only to its operational team but also to the senior authorities overseeing it.

The consequences of police action continue through formal review. After a man dies during an operation, the Independent Police Complaints Commission is already involved, an internal review must be prepared, and a press release needs agreement. At the first debriefing, Jo is still haunted by the dead man’s expression and believes it will take weeks rather than days for the memory to recede. Her phone vibrates with a call from Agata, but she switches it off and puts it back in her bag so she can remain with the meeting. Manchester is therefore the setting not just for pursuit and evidence-gathering but for the institutional and personal reckoning that follows a fatal operation.

A city of work and refuge

Manchester’s narrative geography encompasses professional refuge as well as police infrastructure. Jo chose to move to The Quays partly because of its proximity to her National Crime Agency office and partly because it offered a quiet, retreat-like atmosphere. In a domestic scene, Agata rests an arm around Jo’s waist and describes the place as somewhere the rest of the world seems unable to reach them; Jo recognizes what she means. The location supplies a counterpoint to the city’s urgent investigations: it is still connected to Jo’s work, yet she also values it as a space apart.

Other details extend Manchester beyond the immediate police team. A suspect identified through a vehicle registration is reported to live in Trafford, have a male partner, and work in the claims investigation branch of a major insurance company in Manchester, with no previous convictions. Separately, Jo and her colleagues seek information about a deceased man through the council’s Street Life team and are directed to Urban Outreach, where the manager recognizes him by his street name. These encounters place the investigation among the city’s workplaces and support services as well as its police buildings. Together, they make Manchester a connected but unresolved landscape: a place where evidence can be gathered from many parts of civic life, while the meaning of each clue remains subject to careful investigation.
