Maintaining Wealth to Gain Impunity
In Saltwater, the Lingate family’s identity is built around maintaining a facade of extreme wealth to protect them from legal and moral consequences. The novel illustrates that their immense financial power allows them to operate outside the normal bounds of accountability, treating even violent death as a public relations crisis to be contained through money, influence, and the strategic control of information. This insulation fosters a sense of impunity that enables them to commit and conceal horrific acts, believing their fortune makes them untouchable. However, the Lingate appearance of wealth is a “long con” designed to mask a history of deceit, financial ruin, and moral bankruptcy. This lifelong performance is sustained through manufactured family myths, symbolic props that project false value, and ritualistic displays of control, reflecting their understanding that losing their wealth means losing their power.
The family’s origin story is the foundational lie in this performance—a tale of “aw-shucks luck” crafted to legitimize their status and erase a history of ruthless acquisition. Helen recounts the cherished myth of her great-grandfather accidentally striking oil while prospecting for gold. The reality, which she learns in college, is far more predatory: The family “had swindled their way into the largest oil lease in California” by cheating a wildcatter’s widow out of her profits (11). This initial deception, which recasts a swindle as an American dream, establishes the family’s core understanding that wealth will grant them power, regardless of the moral cost. This is passed down through generations, defining their response to every crisis that follows.
The family’s wealth does provide a financial insulation that grants them the power to literally get away with murder, and the members view a criminal act as a “family issue” to be handled with discretion for decades. Their wealth allows them to manipulate legal processes and public perception, a narrative they reinforce with their annual pilgrimage to Capri. This return to the villa where Sarah died is a performance of untroubled continuity at the site of their greatest scandal. As Lorna observes, “every year they come back here to prove it’s true” (15), that Sarah’s death was an accident. The performance finally implodes on the island of Gallo Lungo, where the family’s secrets are violently exposed in front of an audience of their peers. This public unraveling proves the Lingates’ belief: that people lose their power and impunity when their lack of wealth is exposed.
Ultimately, the Lingate oil fortune has been gone for decades, and the family has been secretly “living off Naomi’s largesse for years” (267). This dependence on Naomi’s fortune makes her the true center of power, which she wields to enforce her will. The entire structure of protection is built on her money and the family’s fragile cohesion. When Helen finally weaponizes their secrets against them, this cohesion shatters, and the insulation dissolves instantly. The Lingates’ downfall reveals that while wealth can build a fortress against the outside world, it offers no protection from the decay within.
Jealousy as a Corrosive Force
Katy Hays’s Saltwater positions jealousy as the central, corrosive agent in the Lingate family’s downfall. Far more destructive than any external threat, envy—including professional, romantic, and fraternal—fuels a cycle of betrayal, manipulation, and murder that consumes the family from within. The novel demonstrates that in the Lingates’ insulated world, the perception of being surpassed or betrayed by a loved one is an existential threat, triggering violent acts of self-preservation that ultimately lead to total destruction. This corrosive emotion is the true, hidden engine of the tragedies that define and ultimately demolish the Lingate dynasty.
Richard’s professional jealousy of his wife, Sarah, directly precipitates the novel’s inciting tragedy. Sarah recalls that as her playwriting career began to flourish, Richard’s faded, and her success seemed to “rattle him.” His violent opposition to her new play, Saltwater, stems from his resentment of her superior talent, as he later reveals that he barely read the play before suppressing it. As Sarah muses, “Sometimes […] I think he lost his mind just because it was mine, and because it was good” (182). This envy culminates in their confrontation in the gardens of Capri, where, in a fit of anger, he pushes her and leaves her for dead, all to suppress her work and the unflattering truths it represents. His jealousy makes her talent a threat that he feels must be neutralized.
The most overtly violent force in the novel is Naomi’s consuming romantic jealousy. Having long suspected Marcus’s affair with Sarah, her resentment explodes when she believes he is repeating the pattern with Lorna. This is foreshadowed by Stan Markowitz, who needles Marcus about his infidelity in front of Naomi on his yacht, knowing it will provoke her. Naomi’s jealousy is the direct cause of the first murder; after watching Marcus cradle Sarah’s injured body, she takes matters into her own hands and pushes the woman she believes to be Sarah off the cliff. Thirty years later, she orchestrates the family’s final, public implosion on Gallo Lungo by revealing the secret of Helen’s parentage. This act is a desperate punishment for Marcus’s betrayals, proving her jealousy is a force capable of destroying the entire family structure.
The lifelong fraternal jealousy between Richard and Marcus provides the novel’s explosive climax. Their dynamic has always been defined by Richard’s status as the “weaker” younger brother and Marcus’s role as the competent, controlling heir. This deep-seated resentment detonates on Gallo Lungo when Richard learns the truth: Marcus let him believe he was a murderer for three decades to cover up his own affair with Sarah. The revelation that Marcus is Helen’s biological father is an additional, unforgivable betrayal. Richard’s subsequent physical assault on Marcus, fueled by a lifetime of jealousy, leads to Marcus’s death, completing the family’s violent self-immolation.
Survival by Adopting the Enemy’s Tactics
Saltwater argues that escaping the suffocating control of the ultra-wealthy requires adopting their own ruthless tactics of deception, manipulation, and cutthroat self-preservation. Helen and Lorna, initially victims of the Lingates’ oppressive system, only achieve true freedom when they abandon moral compromise and weaponize the family’s secrets against them. Their journeys suggest that in a world where power is absolute, survival is a matter of strategic, and often brutal, appropriation of the enemy’s methods, culminating in a series of morally questionable choices that secure their liberation.
Sarah Lingate’s final play, Saltwater, serves as the original blueprint for this survival strategy. Trapped in a stifling marriage and feeling her artistic identity erased, Sarah writes a play that dramatizes her family’s deepest secrets, including their financial ruin and the affair between Marcus and herself. This act of turning private shame into public art is a direct assault on the Lingates’ most valued asset: their pristine public image. Though her attempt to reclaim her narrative leads to her murder, the manuscript survives as a potent weapon. Thirty years later, Helen uses this same play to orchestrate her family’s final downfall, proving the lasting power of Sarah’s original tactic of exposing the Lingate family to liberate oneself from them.
Following this blueprint, Helen and Lorna deploy Sarah’s strategy by devising a blackmail scheme that mirrors the Lingates’ own history of using money to solve problems. After discovering that her father liquidated her inheritance, Helen realizes she must “get out with something” (49). She and Lorna use Sarah’s necklace to demand €10 million in exchange for their silence about its reappearance. This act is a critical turning point for Helen, transforming her into an active participant in her own liberation. By co-opting the Lingate method of financial leverage, she begins to fight back on their terms.
The novel culminates in two ultimate acts of ruthless self-preservation. Helen orchestrates the family’s public implosion on Gallo Lungo by giving Saltwater to Richard, knowing its revelations will pit her two fathers against each other. Her plan results in both their deaths, Marcus’ in the moment and Richard’s presumably years later in Italian prison, but it succeeds in shattering the family’s power structure and securing her inheritance. Lorna ensures her escape by faking her own death, pushing an innocent girl, Martina, overboard so her body would be misidentified, allowing Lorna to disappear with the money. Lorna’s chilling conclusion: ”I would always, no matter the price, save myself first” (322), is the theme’s ultimate expression. To truly escape the Lingates, she engages in their same pattern of deception and elimination, prioritizing her survival above all else.
