Zoe’s discovery begins with three brown envelopes that bring an old, private threat into the present Chicago investigation. The gray ties inside them become the first concrete bridge between her history with Rod Glover and the murders under review; the connection is compelling, but she knows she must establish it through evidence rather than rely on her past suspicion.

The Envelopes and the First Connection

When Zoe is summoned to the front desk, a man introduces himself as a fan of her work and produces three brown envelopes. Each bears her name but no address, and the handwriting matches envelopes she has kept at home in Dale City. The man says he found them separately: one at Foster Beach, another in Humboldt Park, and the third at Ohio Street Beach. Zoe recognizes the pattern before she answers. When she turns the envelopes over, three gray ties fall onto the table, resembling the ties sent to her before. The objects make the encounter more than an unsettling delivery: their repeated appearance at Chicago locations associated with the investigation suggests that someone knows both her history and the significance she attaches to the ties. Zoe suspects Glover, but the envelopes alone do not prove who sent them or establish that he is responsible for the current murders.

Reconstructing the Pattern Across Time

Rather than take her instinct as proof, Zoe works through the records. With Scott’s help, she searches the CLEAR system for Chicago cases involving rape or strangulation from 2002 onward; the database cannot reach back to 1998, when Rod Glover disappeared from Maynard. The work is taxing, and after dozens of reports she has to pause before continuing. The search eventually yields two unsolved murders from 2008, seven months apart, that bring the older case and the present investigation into the same frame.

Shirley Wattenberg was found in the Little Calumet River beneath the bridge on Woodlawn West Avenue. The means of strangulation was missing, but the marks described in the report suggested a wide, smooth, flexible ligature; a detective had considered a belt, though the evidence did not show a buckle. Pamela Vance was found in Saganashkee Slough with a tie around her neck. Both women had been found in water, and the photographs of Wattenberg’s body—naked and partly submerged—recalled the way the Maynard victims had been discovered. For Zoe, the missing ligature in one case and the tie in the other are not incidental differences so much as a possible variation within a repeated method.

The case history also gives her a way to understand the long gap between the killings. She finds no additional cases through 2016, but does not treat the pause as proof that the killer stopped permanently: a serial offender might go months or years without a known murder, conceal a body, or kill elsewhere. Her working sequence is three Maynard murders in 1997, two Chicago murders in 2008, and five further murders between 2014 and 2016, with the later cases linked in method and signature to the 2008 pair. She sees the pattern as a stronger basis for approaching Tatum Gray and Lieutenant Martinez than her old accusation alone, though she remains aware that the gray ties and her belief about Glover’s identity still require a careful, evidentiary explanation.

When she eventually tells Tatum about the two Chicago victims, she connects them to the Maynard killings: in both cases, women were strangled and found in or beside water, and the earlier investigation ended without a conviction after the man taken into custody died in his cell. Tatum considers whether the two periods might reflect the same underlying need. Zoe rejects that as too general an explanation; her conclusion is that the same man committed the murders. The discovery therefore moves from a suggestive resemblance to a specific accusation, while leaving her with the task of persuading others that the timeline and recurring details can withstand scrutiny.

The Earlier Warning and Its Afterlife

The connection to Maynard carries a history of failed recognition. At fourteen, Zoe had already named Rod Glover as a possible serial killer to an officer, carefully setting out the research behind her suspicion: how Glover seemed to fit traits associated with psychopaths, why she had visited Durant Pond, and what she had noticed inside his home. She described the pornography, underwear, and shoebox she had seen there, while emphasizing that she had possessed a key. The officer showed some interest, but treated her account as a frightened teenager’s accusation rather than a lead demanding a search.

The decisive obstacle was an alibi. Glover had joined a search party for Clara, and the officer told Zoe that all seventy-eight people on it—including himself—were accounted for at the time of Clara’s death. He warned her not to keep calling her neighbor a serial killer. The explanation closed the matter for the police, but not for Zoe: she remained convinced that Glover was responsible and had already learned how readily an official account could turn suspicion into dismissal.

The alternative suspect made that failure harder to accept. Officer Will Shepherd described Manny Anderson as an isolated young man whose teacher had mentioned strange cartoons, frequent Dungeons and Dragons games, and the fact that he had never had a girlfriend. To Zoe, those details established nothing; the police had found someone who loosely matched a stereotype and begun fitting the case to him. She saw a bitter reversal in being called hysterical when her own case against Glover had been grounded in deliberate research, while weak assumptions about Anderson were treated as persuasive.

The old accusation thus shapes the present investigation as well as Zoe’s judgment of it. She fears that raising Glover’s name will make her seem fixated on the man she accused as a girl, or jeopardize her place on the case. Meanwhile, the envelopes have kept the earlier encounter active across years of silence: whenever another arrived, the threat seemed to reach back toward the fourteen-year-old Glover had once intimidated. Now she believes he is in Chicago and killing again, and the possibility that she was right before intensifies both her resolve to prove the connection and her fear that she will again be ignored.

The Claim Reaches Beyond the Case File

Zoe’s suspicion is not confined to the evidence she can present to investigators. She tells her sister, Andrea Bentley, that Glover may be in Chicago. Andrea remembers the night he nearly killed them: she and Zoe were locked in Zoe’s room while he shouted from the other side of the door. As a child, Andrea had trusted her older sister to protect her and soon moved on from the terror of that night; Zoe, by contrast, had carried its implications forward. Now Andrea asks whether Zoe has seen Glover. Zoe has not, and can offer only reasons for suspecting he is nearby—a distinction that keeps her claim unresolved even within her family.

The discovery therefore leaves Zoe with two burdens that the evidence cannot collapse into one: establishing that the Chicago murders belong to the same pattern as Maynard’s, and persuading others that the man she accused years earlier is the link. The recurring ties give her a material trace, while the old night with Glover supplies the personal history behind her certainty. Neither, by itself, settles the case. The tension between what Zoe recognizes and what she can prove turns the connection into an ongoing test of credibility, not a completed identification.
