The murder of Joe Silvermann is the turning point that transforms Sarah Trafford’s uneasy visit to his office into a threat directed at her. Its apparent evidence points toward suicide, but Sarah rejects that account almost at once; the missing file and drugs planted to implicate her make the killing part of a larger attempt to control what she knows and what the authorities believe.

The discovery at the office

The last time Sarah had visited Joe’s office, roadworks had complicated the journey. This time the narrow street was empty. Its stillness was briefly interrupted by a man in a white jacket emerging from the Italian restaurant opposite, looking along the road, then lighting a cigarette, and by a tour bus passing the end of the street. These incidental movements sharpen the quiet around the office rather than dispel it.

Sarah found the outer door unlocked and climbed the stairs to Reception, whose door stood ajar. She called Joe’s name and heard nothing. She wondered whether Zoë Boehm might have returned, but the silence made that unlikely; then she reasoned that Joe had probably stepped out nearby and would soon be back. Her first knock was tentative, her second more businesslike. She considered leaving a cheque on his desk, because paying him seemed a quick way to put their unfinished business behind her. The inner office door was open too, and she went in.

Only afterwards could Sarah bring the discovery down to what she called its barest essential. For a second, she thought Joe was wearing a bright red tie. That comforting impression quickly vanished. What remained was the sight of Joe’s own hand holding a razor. The detail of the hand does not reassure her or make the scene convincing: Sarah is not deceived by the arrangement, even as her mind briefly supplies the less terrible image of a familiar, living man in office clothes.

A staged explanation Sarah refuses

The tie and razor establish the contrast on which Sarah’s understanding of the murder depends. At first glance, the office offers the possibility of an ordinary explanation for Joe’s death; on reflection, the image is a fiction that lasts only a second. Sarah’s account keeps the staging and her recognition of it close together, making her immediate perception part of the event’s suspense. The apparent scene does not settle what happened. It prompts her to examine who might have altered the evidence and why.

Her later reasoning distinguishes between what she knows and what she suspects. She concludes that Joe has been murdered and that the arrangement is intended to warn her. She cannot picture Gerard Inchon personally entering her house, finding her purse, planting drugs, or killing Joe with Joe’s razor. Rather than treating that difficulty as proof of Gerard’s innocence, she takes it to imply that he has accomplices. But the precise route by which Gerard became her suspect escapes her while she is exhausted. Her suspicion is therefore consequential but not conclusive: she identifies a likely connection without claiming to have reconstructed every act or participant.

The missing file and the frame-up

The strongest clue to Sarah is not something left in the office but something removed from it. She finds no record of herself, Sarah Trafford, née Tucker, among Joe’s files. She believes he would have kept one: although she had spent only a few hours with him, she knew him well enough to expect that he would document a client and the work he had undertaken. He had not banked her cheque, but she separates that lapse from the question of paperwork; in her view, failing to complete a task did not mean failing to record it.

The missing file changes the meaning of Joe’s death. Sarah infers that someone removed it after killing him, and reads its absence alongside the drugs used to set her up in a drug ring. The two acts serve different but connected purposes: the file erases the trace of her dealings with Joe, while the planted drugs make her vulnerable to suspicion. Sarah understands the murder not as an isolated attack but as a warning accompanied by an effort to discredit her. She also fears that Dinah Singleton has been hidden and may be dead, though she does not know which; the murder therefore deepens, rather than resolves, the uncertainty surrounding the missing girl.

Zoë’s corroboration and the murder’s consequences

When Zoë confronts Sarah, she gives the murder an independent context. Zoë describes Joe as a limited detective, prone to foolishness and lies and unusually easy to exploit, but insists that drugs were not part of his life: he neither used nor sold them. In her account, somebody killed him and planted drugs on him. Her judgment turns the evidence against Joe into evidence of deliberate fabrication, while her anger makes clear that she intends to pursue the killer.

Zoë also confirms why the absent file matters. Joe, she says, kept a list of the lists he kept; forgetting to create a record of Sarah was less plausible than the removal of one. She points out that Sarah told the police her visit on the day she found Joe was her first time in his office, and asks why she lied. The question complicates the warning: Sarah is not only a witness trying to read a staged death but also a person whose own account has concealed part of her connection to the victim. Joe’s murder consequently leaves her exposed on two fronts, as the target of an apparent frame-up and as someone whose credibility can be challenged. The office scene supplies no final identification of the killer; it sets Sarah and Zoë against a murder designed to obscure both the truth and the relationship that led Sarah there.
