Sarah Tucker and Zoë Boehm

Sarah Tucker and Zoë Boehm’s relationship is recast by Joe Silvermann’s murder and Sarah’s search for Dinah Singleton: what had been a connection through Joe becomes a direct, uneasy alliance between two women who know the cost of leaving someone behind. Their reunion is marked by missed communication and grief, but also by a shared refusal to let fear settle the question of what either of them owes to Dinah.

A friendship shadowed by Joe

Before the women meet again, Sarah is already thinking about Zoë. During a quiet afternoon at an inn, she remembers that Zoë had recently pumped salt water from her and taken drugs out of her system. She recalls her as unsentimental, and remembers that Zoë had promised to check up on her. Sarah had left before that could happen. In the aftermath of Joe Silvermann’s death and her own flight, the unfinished promise comes to feel like one more responsibility she has evaded.

Sarah decides that letting Zoë know she is alive would at least count for something. She calls directory enquiries, writes down the number for Oxford Investigations, and rings the office. No one answers. The silence becomes vivid in her mind: an empty office, dust gathering on the shelves, and the imagined absence of Joe, who will never return to wait for the phone or talk to a client. Her attempt to contact Zoë therefore runs straight into the loss they share. Sarah hangs up before the thought makes her cry, but her wish to reach Zoë remains.

Zoë, too, is connected to Joe through the habits that persist after his death. When she later explains how she traced Sarah, she says that Joe never forgot to switch on the answering machine; she, by contrast, had forgotten to turn it on. At the office she found that the latest call had come from Scotland, a place where she knew nobody. It took her hours to understand that the call might have been Sarah’s. A small lapse in office routine thus becomes the opening through which the two women find one another again.

The reunion and the news

When Zoë finally sits beside Sarah on a bench overlooking the sea, Sarah is lethargic and does not immediately turn to look at her. They sit together in silence for several minutes, watching the water. Sarah experiences the waves as smoothing her thoughts; the quiet gives their reunion a pause before either woman has to explain herself. Sarah says she had expected Zoë, and Zoë answers with the wry observation that finding missing people is one of her specialties. Sarah then tells her she had tried to call.

Zoë’s first response to Sarah’s survival is a mixture of astonishment and exasperation. She remarks that Sarah seems to land on her feet, then begins to refer to Joe. Sarah cuts her off: she has seen a man die, nearly died herself, and does not want to be congratulated on her luck. The exchange establishes a limit on how Zoë can approach her. Sarah is alive, but she rejects any account of that survival as uncomplicated good fortune; the danger remains immediate, and the death she has witnessed is not an incidental detail.

Zoë does not press the point. Instead, the women turn to how she found Sarah. Zoë’s account links the missed call from Scotland to the description she gave to the man who answered when she rang the number. Sarah’s changed hair briefly complicated the identification, but Zoë says it did not prevent her from working out where Sarah was. Their reunion depends on both women acting on incomplete information: Sarah makes an unsuccessful call, and Zoë recognizes its possible meaning only after hours have passed.

Joe’s murder and the danger around Sarah

Sarah recognizes that her recent escape has narrowed her attention to her own predicament, while other people have suffered losses of their own. She makes a point of telling Zoë what happened: Rufus killed Joe, tried to kill Sarah, and was a spook. The disclosure gives Zoë the explanation she needs for Joe’s death and for the threat that has driven Sarah into hiding. For Sarah, telling her is also an acknowledgement that the murder belongs to Zoë’s grief as well as to Sarah’s guilt and fear.

The news carries an added weight because Zoë did not see Joe dead, but she buried him. Sarah’s memory of him slumped over his desk, with a razor still in his hand, makes the murder’s staging part of what she cannot put aside. She believes Rufus killed and arranged him, and that such a killing suggested practice; even with Rufus dead, she fears there may be others like him. This is the threat Sarah brings into the relationship: the danger has not necessarily ended with the man who attacked her, and closeness to her could expose Zoë to it.

That fear shapes Sarah’s attempt to send Zoë away. She reasons that the people pursuing her are not pursuing Zoë, and may not even know Zoë is there. If they find Sarah, she warns, they will find whoever is with her too. Her urging is not a rejection of Zoë but an effort to keep her outside the danger Sarah believes she attracts. The concern is reciprocal in an imperfect way: Sarah tries to protect Zoë by separating them, while Zoë sees withdrawal as a moral choice with consequences of its own.

Choosing not to walk away

Zoë refuses Sarah’s proposed separation. She says that leaving would make her no better than the people after Sarah. Her answer shifts their bond from shared grief into a conscious commitment: she will not treat self-preservation as an automatic excuse to abandon someone in danger. Sarah answers that Zoë could end up dead, but Zoë counters that Sarah is not dead yet and has managed to survive so far. The exchange does not erase the risk; it shows the women confronting it from opposite sides, Sarah emphasizing the threat and Zoë the obligation not to yield to it.

Zoë makes that obligation concrete by asking whether Sarah would walk away and leave Dinah Singleton behind. The question connects their immediate disagreement to the search that has given Sarah a reason to continue. Sarah’s concern for Zoë has led her to urge flight, but Zoë insists that the same logic would be difficult to accept if Dinah were the person left behind. Their alliance is therefore not based on reassurance that they will be safe, or on the restoration of an easy friendship. It rests on a harder recognition: both women understand the danger, both are marked by Joe’s absence, and Zoë chooses to stay involved because Sarah’s search for Dinah cannot be separated from the responsibility to act.
