Sarah Tucker and Joe

Sarah Trafford’s relationship with Joe Silvermann changes from a working investigative connection into a bond defined by bereavement and guilt. After Joe is murdered, Sarah does not treat his death as a loss separate from her own escape: she repeatedly imagines the life he would still be living if she had acted differently, and measures her obligations to the living against the absence she believes she helped create.

Professional Connection and Shared Circumstances

Sarah and Joe’s connection begins through investigative work. Joe’s office, Oxford Investigations, is part of the life Sarah imagines him continuing after his death: he might be there waiting for a call or talking to a new client about previous ones. That ordinary professional future matters because it makes his loss concrete. Sarah does not remember him only as a victim or as a figure in the danger surrounding her; she pictures the routine work and conversations that have been cut off.

Their relationship is also entangled with the events that make Sarah a fugitive. As she later explains to Zoë Boehm, the man she knew as Rufus killed Joe, tried to kill Sarah, and was a spy. The disclosure places Joe’s death within a larger chain of violence, but it does not erase Sarah’s private conviction that she bears responsibility. The facts of the murder and Sarah’s account of her own culpability remain distinct: she identifies Rufus as Joe’s killer, yet thinks of herself as having killed Joe in all but the literal sense.

Grief as Counterfactual Responsibility

At an inn, after Michael Downey has gone to sleep, Sarah spends a quiet afternoon reading a paperback. Joe remains present in her thoughts. Each time she looks up, she returns to the belief that she has effectively killed him; without her, she imagines, he would still be at work, waiting for a telephone call or speaking with a client. Her imagined scene is deliberately ordinary. It is not a heroic future she pictures for Joe, but the next unremarkable stretch of his working day—and its ordinariness sharpens the sense of what has been taken away.

Sarah’s blame is not presented as a proven account of the circumstances of Joe’s murder. It is the language of grief and counterfactual thinking: she turns the difference between her survival and his death into a personal debt. The thought recurs rather than resolving. While sitting alone, she wishes Joe peace and imagines him beyond the world, then finds herself wanting to look at the stars. Her attempt to place his absence against a vast universe offers a moment of perspective, not release from responsibility.

The same guilt shapes a small decision to contact Zoë. Sarah has recently fled before Zoë could check on her, despite Zoë having helped her through a drug crisis. Sarah tells herself that letting Zoë know she is alive would at least acknowledge some responsibility she has been avoiding. She calls Directory Enquiries, writes down the number for Oxford Investigations, and rings the office. No one answers. The unanswered call turns a practical attempt at contact into a scene of absence: Sarah imagines dust settling in the vacant office and Joe never coming back to it. She hangs up before the thought makes her cry.

What Sarah Tells Zoë

When Sarah meets Zoë again, she does not immediately make Joe’s murder the subject of their conversation. Zoë begins to refer to what might have happened if Joe had not been involved, but Sarah cuts off the suggestion that she is simply lucky to have survived. She stresses that she has seen a man die, nearly died herself, and may still be in danger. The exchange shows how the two women approach the same loss differently: Zoë starts from the counterfactual possibility of Sarah’s death, while Sarah resists having survival presented as uncomplicated good fortune.

Sarah then recognises that Zoë, too, has suffered a loss and needs to know what happened. She identifies Rufus as the person who killed Joe and tried to kill her, and says he was a spy. After Zoë absorbs the news, she hands Sarah a bottle; Sarah drinks and tells her the larger story, including who Michael is and where Dinah is. The disclosure is more than a report of the murder. It is a return to trust and an effort to let Zoë share the facts Sarah has been carrying alone.

The Relationship’s Aftermath

Joe’s death continues to affect Sarah through both memory and action. His empty office gives her grief a physical address; the unanswered telephone makes the permanence of his absence impossible to mistake. Her later explanation to Zoë restores the event to a shared account, but the evidence does not show that Sarah’s self-accusation disappears. Instead, the relationship remains present in the tension between what she knows—that Rufus killed Joe—and what she feels—that Joe would still be alive but for her.

The relationship is therefore defined less by a final reconciliation than by an unfinished obligation. Sarah cannot return Joe to the professional life she imagines for him, and calling his office cannot reach him. What she can do is remember him, acknowledge the loss to Zoë, and stop withholding the circumstances surrounding it. Her grief turns the ordinary details of Joe’s work and the silence at Oxford Investigations into measures of a life interrupted.
