The murder of Carolyn Polhemus returns not as a settled case but as Rusty Sabich’s reconstruction of a crime that has shaped his life and remained officially unresolved. He identifies Barbara Sabich as the person who could have planned and carried it out, describing how she might have created an alibi and manipulated evidence. Yet the account does not lead to a prosecution or an authoritative public resolution. Its force lies in the collision between Rusty’s private understanding, his history with Carolyn, and the fact that he chooses not to expose what he believes.

Background and Retrospective Recognition

The murder occurred on April 1, at Carolyn Polhemus’s apartment. The account returns to it through later recollection rather than through a contemporaneous scene: Rusty pieces together a possible sequence and sets it against details that had once seemed incidental. His explanation makes domestic objects and investigative traces newly consequential, but it remains his reconstruction, not a verdict delivered by a court.

A black iron garden tool, known as a Whatchamacallit, becomes the most tangible link between that past and Rusty’s present. It was among the equipment brought to the Sabich home after the death of Barbara’s father, delivered by Barbara’s mother. The tool could serve several ordinary uses around a yard; Rusty later recognizes that it was also the instrument used in Carolyn’s murder. The contrast between its practical place in the household and its role in the crime makes the past persist in an object that had never been removed from ordinary life.

Rusty’s Reconstruction of the Crime

Rusty’s account describes Barbara preparing before she went to Carolyn’s apartment. She stopped at the university and used its computer system, activity that could supply an alibi and occupy enough time to make that account plausible. In his reconstruction, Carolyn expected Barbara and let her into the apartment. Barbara had brought the garden tool and cord, and she left a glass at the bar as part of the scene she arranged afterward.

The planted biological evidence was another part of that design. Rusty attributes to Barbara the use of material she had collected and her attempt to make it appear connected to the crime. He emphasizes that the plan depended on what she thought investigators would examine and what she assumed would escape scrutiny. This is not presented as a confession from Barbara; it is Rusty’s detailed explanation of how he believes she constructed a misleading account of the killing.

The proposed sequence also includes Barbara unlocking the doors before leaving. In Rusty’s telling, that action helped shape how the apartment and the circumstances of entry would be understood. His reconstruction makes the crime appear less like an isolated act than a sequence of choices, each intended to direct attention away from its maker. He does not claim that Barbara foresaw every consequence: the later investigation uncovered details that, in his view, she had not anticipated.

Evidence and the Household Object

Rusty connects Barbara to the investigation through several kinds of forensic evidence. Fibers from the carpet in her home were found on the hem of her skirt, and investigators recovered hairs that could have come from her. He also points to the detailed examination of the semen specimen, the tracing of a call through telephone records, and a third fingerprint on the glass. Each clue has its own limits, but together they form the pattern on which Rusty bases his account.

The significance of the Whatchamacallit is personal as well as evidentiary. After the trial, Rusty noticed dried blood and a blond hair on one of its teeth. He stared at the tool, then carried it to the basement and washed it in the laundry tub; Barbara came downstairs while he was doing so. The episode joins recognition to concealment: Rusty has encountered evidence that could expose the past, yet the act he describes is to clean the object rather than bring it to investigators. The tool’s inheritance through Barbara’s family makes the discovery especially close to home without establishing, by itself, who used it.

Guilt, Silence, and the Unresolved Case

Rusty’s reflections widen beyond the mechanics of the crime. He considers how a person can entertain a plan, take an initial step, and gradually cross a boundary while telling himself that no real harm has yet been done. He apologizes to Barbara for his own part in their shared history, while acknowledging that the reasons behind killing are not fully comprehensible even to the person who acts. His language about having deliberately reached toward Carolyn underscores his own desire and responsibility; it does not, in itself, settle who killed her.

That distinction keeps the ending morally unsettled. Rusty’s reconstruction accuses Barbara, but his willingness to state it aloud is not the same as turning it into a public case. He tells her that he wants what each of them knows to be spoken between them and says he wants to go on, in part to limit the damage to their lives. The disclosure therefore functions both as an accusation and as an effort to establish the terms of their future, not as a formal appeal for justice.

The murder remains unsolved. Rusty says that no one is pursuing it with him, and that trying two people for one crime would be practically impossible. When a jailhouse claimant later tries to confess, Rusty sends Lipranzer to take the statement; Lipranzer reports that it is worthless. That episode offers no new resolution. The case ends where Rusty’s private knowledge and public silence meet: he has articulated a detailed account of Barbara’s actions, but the crime remains without an official finding.
