Sorenson’s Plumbing is a working plumbing shop that becomes a focal point in Zoe Bentley and Tatum Gray’s attempt to identify a suspected killer through the traces left by earlier crimes. Its importance lies not in any established crime at the premises, but in the way the shop connects a developing suspect lead to a real workplace, an employee, and records of recent service calls. The investigation’s attention shifts from predicting whom the killer might target next to following the practical details that could reveal where he had been.

Setting and First Visit

Zoe first enters Sorenson’s Plumbing after asking her driver to wait; she expects to be inside for only ten minutes. Whatever had set off her alert signals, she decides it was not the driver, gets out, and walks into the shop. The only man there is an employee named Jeffrey, who greets her formally. The brief encounter establishes the premises as an accessible place of business and gives Zoe a reason to return to it later, but it does not itself establish that the shop or its employee is involved in a crime.

The later identification of Clifford Sorenson as a plumber makes the business newly significant. An older neighbor confirms that Sorenson is a plumber rather than an electrician and adds that his mother called him Cliff when he was young. That exchange supplies a name and occupation, not proof: the shop becomes relevant because it gives the investigators a concrete place to pursue the plumber lead, while the distinction between a plausible lead and demonstrated guilt remains essential.

From a Suspect Lead to a Workplace

The shop enters an investigation shaped by uncertainty about how to find the killer. Earlier, Zoe argues that the bodies’ public locations are also likely to be empty at night and lack security cameras; she sees no clear evidence that the killer is seeking publicity or playing a game with police. In her analysis, the way bodies are posed may matter as much as where they are found. The selected locations therefore offer investigative questions, but do not by themselves point to a particular business or suspect.

The map used in the task-force discussion reinforces that caution. It marks Ohio Street Beach and the Brighton Park area where Krista Barker had worked on the last night she was seen, and the distance between the marks makes clear that the killer is not confined to one Chicago neighborhood. The team also recognizes that a stakeout would be difficult to guide: the group considered at greatest risk is prostitutes, yet the proposed description of a possible offender is so broad that it fits many men, including men in the department. Sorenson’s Plumbing matters in this context as a specific investigative lead, not as a location already linked to the murders by the geographic pattern.

A Return Without a Warrant

When Zoe and Tatum return, a single van is parked in front of Sorenson’s Plumbing beside a small warehouse, and one of the plumbers is away. Zoe gets out and heads toward the remaining van; Tatum catches up and reminds her that they have neither a warrant nor permission to be there. Her answer is practical: she has visited before and can say she came to ask further questions. She also believes that calling Lieutenant Martinez would get them nowhere except out of Chicago. The decision brings them to the shop through informal persistence rather than official authorization, and Tatum’s warning makes the limits of their access explicit.

Inside, Clifford Sorenson is seated behind his desk reading a newspaper. He recognizes Zoe as the person from the Federal Bureau of Investigation, and she introduces Tatum as her partner. The office scene places the investigation face to face with Sorenson at his workplace, but the evidence presented here does not establish what he knows or whether the shop has any connection to a particular crime. The detail of the newspaper and desk locates him in an ordinary working setting; it does not resolve the suspicion.

Records as an Investigative Route

The inquiry turns from Sorenson’s presence to the work his plumbing business may have generated. Tatum asks for a list of all the clients Sorenson’s brother has handled in the previous three months. The reply—that there could be hundreds of names—indicates the scale of the records they are seeking, while Tatum’s proposal to check them makes the client list the next practical step. The request does not mean that those clients are suspects or that any visit has been tied to a murder. Rather, it converts the shop from a place where a lead can be questioned into a possible source of information about recent movements and contacts.

That method echoes the investigators’ broader change in emphasis. After nearly catching the killer, Zoe believes he will adapt: he may kill a future victim more quickly and choose someone vulnerable who is not a working girl, making victim-based prediction less reliable. She argues that the team must instead trace the breadcrumbs in his past crimes and his earlier mistakes. Sorenson’s Plumbing embodies that shift from forecasting a future target to examining ordinary traces—occupation, workplace, vans, and client records—for a usable link to prior events. Its narrative significance remains investigative and provisional: it is a place to follow a lead, not proof that the lead is correct.
