"Balthazar" continues the narrative that began in the first volume of the Alexandria Quartet, "Justine." This time, we are presented with many of the events from "Justine" but from the perspective of the psychiatrist Balthazar. His account unceremoniously disrupts and complicates our understanding of the events. A few years after the events in "Justine," the narrator, whose name we finally learn is Darley, has moved to an island with the child that Melissa had with Nessim. Here, Balthazar drops off what he calls his "interlinear," a literary recounting of the previous events from his point of view. Darley spends much of the novel reading and reflecting on this account, which completely undermines his previous understanding. We learn that Justine was actually in love with the novelist Pursewarden and used Darley as a decoy to cheat on her husband. We also read about Scobie, a mutual friend of many of the characters, who is killed while in drag, possibly while trying to pick up a sailor for a trick.
In "Balthazar," Durrell draws the reader's attention to the meta-fictional aspects of the story in at least two ways. Firstly, Balthazar's "interlinear" reconfigures Darley's understanding of the events in the previous volume, presenting a Rashomon-like series of perspectival takes, none of which can be considered the whole truth. Secondly, Durrell uses Pursewarden as a cipher to shed light on the plight of the novelist or, more broadly, the artist's task. This ambiguity, which can sometimes seem heavy-handed, mirrors Durrell's views on love and erotic relationships in general. He suggests that they are a series of shadows, lies, deceptions, and figments of our fragile imaginations. As with the first volume, the language in "Balthazar" is stunning, filled with wonderful ambiguities and mysteries that wholly capture the essence of Alexandria and its residents for Durrell.
