Chicago enters the novel as one point in a wider map of unsolved assaults: a city where C.J. Townsend finds a case that may connect William Rupert Bantling to a series of earlier crimes, but where the passage of time has already closed off prosecution. Its significance lies in that double discovery—the possible reach of the pattern, and the legal limit on answering it.

Chicago and the Unsolved Case

While searching records from cities where Bantling had previously lived, C.J. finds a report of a rape in Chicago in September 1989. The victim’s account and the crime’s general pattern resemble cases reported elsewhere, including attacks by a masked assailant. Bantling’s AutoTrack history places his former residence no more than ten miles from the victim’s address. That proximity becomes a meaningful investigative lead, though not proof by itself that he committed the Chicago crime.

The case had not produced an arrest or an identified suspect. C.J. sees it alongside other unsolved attacks in different cities, where similar methods had not been enough to make investigators recognize a connection. The Chicago report therefore adds to her suspicion that the cases may share an assailant while also showing how fragmented records and separate jurisdictions left that possibility untested.

Records and the Limits of Investigation

C.J. follows the newspaper lead by contacting police records departments and requesting the reports. By evening, she has obtained reports from all six departments she is investigating. Comparing them, she identifies recurring similarities in how the attacks were carried out, while the records also show the absence of physical evidence that might have established a suspect’s identity. In the novel’s investigative logic, Chicago matters not as a confirmed crime scene belonging to Bantling, but as one part of a pattern C.J. reconstructs from old files, reported details, and his documented addresses.

The inquiry gives C.J. a way to revisit crimes that had remained isolated on paper. Yet a stronger pattern does not automatically make an old case prosecutable. When she checks Illinois law, she learns that the limitation period for the Chicago rape was ten years. Because the crime had occurred more than a decade earlier, the legal opportunity to bring the case had passed.

Narrative Significance

Chicago concentrates a central tension in C.J.’s investigation: the difference between recognizing a possible truth and being able to secure legal accountability for it. The case helps extend the suspected history of Bantling’s crimes beyond the places already under scrutiny, but its unresolved status and expired limitation period prevent that discovery from becoming a prosecution. The city thus marks both the geographic reach of C.J.’s inquiry and one of its hard boundaries.
