Few experiences could be more unsettling than becoming someone else overnight, but few narratives explore the premise as compellingly as The Case of David Zimmerman. On New Year’s Day, thirty-four-year-old David awakens hungover with a fading memory of a one-night stand from the previous night’s party, only to discover that he has become the woman he slept with. In their graphic novel, brothers Lucas Harari and award-winning filmmaker Arthur Harari craft a disorienting yet gripping psychological thriller about living in a body that is not your own while trying to unravel the circumstances behind this impossible transformation.

The story centres on David’s confusion and desperation as he attempts to track down the woman he has become, Rachel Bluem. The Harari brothers resist the temptation to treat the premise as a gimmick, grounding David’s reaction in a convincing mixture of shock, horror, and disbelief. They offer few answers as David, trapped in Rachel’s body, exhausts every lead in his search for her. They also demonstrate how inhabiting a woman’s body exposes him to forms of attention and behaviour that differ sharply from those he experienced as a man. This is the case when Rachel/David tracks down a man who claims that his sister underwent the same transformation, only to face a disturbing advance at an isolated suburban office tower where the man has driven her.

Artist Lucas Harari pens a gloomy atmosphere through his clear-line style and a palette of pinks and purples. Set in northeastern Paris in winter, the story unfolds beneath overcast skies that admit neither sunlight nor hope. The cinematic angles of panels evoke film noir, underscoring the novel’s dark themes. Harari’s meticulously rendered façades, cafés, and metro stations in Belleville, along with the deserted suburbs beyond central Paris, anchor the narrative in places rarely visited by tourists. The result is a Paris that feels at once familiar and uncanny.

The mystery deepens when David, now living as Rachel, is texted a photograph of his former body, clad in an ill-fitting puffer jacket. Convinced that the search is over, Rachel/David races to the scene, only to discover David’s body is inhabited by Samia, a twenty-one-year-old woman whose story is strikingly similar to David’s. After a chance encounter at a party and a night spent with a stranger, Samia awakens to find herself in David’s body. Her only link to her former life is a puffer jacket.

Rachel/David and Samia (now inhabiting David’s body), work together on their investigation into the transformation. However, David/Samia grows further despondent, unable to imagine abandoning her former life and resigned to a form that feels alien. Samia’s suffering invites reflection on the extent to which identity is tied to physical appearance. More troubling still is the life attached to David’s body: friends and family recognize him and expect certain behaviours that feel foreign to Samia. After all, identity is shaped not just by the bodies we inhabit, but also by the social roles imposed on us. With nothing to lose, Samia proposes an experiment: she asks Rachel/David to sleep with her in the hope of reversing the transformation. Whether the phenomenon works that way remains unclear.

The body-swapping premise, the art, the setting, and the characters will appeal to a wide audience. But readers should bear in mind that, as the title suggests, only David’s fate, both inside and out, is resolved. I’d grown attached to the outside of Rachel and the inside of Samia, with whom readers spend considerable time, and I was disappointed that we found out so little about their fates. Let’s hope a sequel is in the works.mRb
