Summary

In the early 1940s, Lisbon is a city on edge—a neutral haven swarming with spies, refugees desperate for escape, and the constant threat of betrayal. Into this tense atmosphere arrive Selene Delmont and Bea Sullivan, two women bound by friendship but led by very different motivations.

Selene, once a privileged American heiress, has been disowned and drawn into the dangerous world of espionage. Recruited to infiltrate Lisbon’s high society, she poses as a secretary in the Portuguese Trade Commission.

Her mission is clear but perilous: identify and expose a Nazi informant who is leaking the identities of refugees and Allied secrets. Selene’s cover involves seduction, cunning, and daring deception.

She learns to wield her charm and intelligence like weapons, attending glamorous parties, gathering whispers, and recruiting a covert network of informants—including a housemaid and a cabaret singer. Yet, beneath her confident facade, she wrestles with guilt, haunted by the suicide of a previous agent and the growing realization that trust is a dangerous luxury.

Bea, by contrast, arrives in Lisbon as a librarian working for the International Documentation Center (IDC). Quiet and cerebral, Bea’s role seems far less glamorous, cataloging books and microfilm for Allied intelligence.

But her personal stakes are high—her fiancé, Pete, is missing in action, presumed a prisoner of war. Driven by hope and love, Bea secretly investigates passenger manifests and POW lists, determined to find any sign of him.

She proves herself indispensable at the IDC, gaining access to sensitive information, but soon uncovers troubling signs of a mole within their ranks. Bea’s journey reveals her own courage, transforming from a passive bystander into an active participant in the resistance, using knowledge and codes as her weapons.

As Selene and Bea pursue their separate missions, their paths cross and intertwine in a city rife with danger. They witness firsthand the desperation of refugees seeking passage out of Europe, the ruthless black market dealings involving wolfram (a valuable resource), and the intricate power plays within Lisbon’s elite.

Selene’s encounters include a mysterious and brooding nobleman, Luca Caldeira, whose own past is marked by tragedy and loss. Their complex relationship offers moments of tenderness amidst the peril.

The novel delves deeply into the shadowy world of espionage: coded messages hidden in lipstick tubes, secret knocks, and sheet music, and risky meetings held in the backrooms of casinos and salons. Selene navigates treacherous alliances, unsure whom to trust—even among her closest contacts.

Bea’s quiet rebellion grows as she gathers clues and breaks codes, revealing the heartbreaking costs of war and betrayal. Throughout the story, themes of loyalty, sacrifice, and female resilience emerge strongly.

Selene’s mission brings her face-to-face with moral dilemmas—how far to go in deception, and what to do when a trusted ally may be a traitor. Bea’s perseverance leads her to painful truths about Pete’s fate, yet also to acts of bravery that save lives.

Together, the two women embody the quiet strength and complexity of wartime heroines, balancing personal grief with a greater cause.

Lisbon itself is vividly portrayed—not just as a backdrop, but as a living character, teeming with refugees, spies, and secrets. The city’s glamorous casinos, opulent salons, and shadowy streets create a tense, immersive setting where danger lurks in every corner.

As the narrative unfolds, tension mounts with betrayals discovered, alliances tested, and covert operations risking everything. Selene and Bea’s lives become increasingly intertwined with the fate of countless refugees and the success of Allied intelligence.

Their courage and wit fuel a resistance effort that, though hidden from history’s grand narratives, plays a crucial role in saving lives. The story builds toward a high-stakes confrontation where loyalty, sacrifice, and identity are put to the ultimate test.

The Librarians of Lisbon offers a rich, suspenseful journey into the heart of war’s shadowy struggles and the women who fought bravely in the quiet corners of history.

Characters

Selene Delmont

Selene Delmont emerges as the central figure of the novel, a disowned American heiress who transforms into a determined and resourceful spy during World War II. Initially motivated by a desire for adventure and redemption, she embraces the perilous world of espionage with a blend of charm, intelligence, and ruthlessness.

Throughout the story, Selene juggles a double life, posing as a secretary by day while cultivating a network of informants by night. Her interactions reveal a complex woman shaped by trauma and loss, yet willing to wield her femininity and wit as weapons.

Despite her tough exterior, Selene is haunted by guilt—particularly the suicide of a previous agent—and struggles with trust, knowing betrayal lurks even among allies. Her relationship with Luca Caldeira reveals a rare vulnerability, showing how her guarded heart yearns for connection amid the chaos.

Ultimately, Selene’s choices, including sparing Marguerite and aiding refugees, underscore her humanity and moral complexity beyond mere spycraft.

Bea Sullivan

Bea Sullivan serves as a poignant contrast and complement to Selene. Where Selene is fiery and bold, Bea is introspective and cautious, carrying her own heavy burdens—most notably the hope and grief tied to her lost fiancé Pete Dawson.

As a reserved librarian working for Allied intelligence, Bea begins as someone who doubts her own strength but grows steadily into a courageous figure who quietly rebels against the constraints around her. Her brilliance shines through her ability to decode secret messages and maneuver through bureaucratic obstacles.

Bea’s personal journey is marked by both determination and heartbreak, especially as she discovers Pete’s fate. Her loyalty to her friends and to the cause manifests in her brave decisions, such as sneaking into restricted areas and organizing refugee escapes.

Bea’s arc is one of growth—from a woman seeking answers to one who creates solutions.

Marguerite

Marguerite represents the moral ambiguities and tragic choices faced by those caught in wartime espionage. Initially introduced as Selene’s contact and mentor, she embodies elegance, secrecy, and sorrow.

Her position as the Orchid—a code name for a key figure in the resistance—places her at the heart of covert operations, yet her story unfolds to reveal a deep internal conflict. Marguerite is eventually exposed as a reluctant traitor, blackmailed into betraying refugees to protect her son in occupied France.

This revelation adds layers to her character, portraying her less as a villain and more as a woman trapped between love and survival. Selene’s decision to fake Marguerite’s death rather than condemn her highlights the complexity of loyalty and mercy in desperate times.

Luca Caldeira

Luca Caldeira is a multifaceted character, a disgraced nobleman with a brash demeanor masking profound grief. His backstory, including the loss of his sister in a Nazi raid, infuses him with both bitterness and a sense of purpose.

Luca’s relationship with Selene is pivotal, as their shared pain and secrets forge a deep, if cautious, bond. His role shifts from an enigmatic outsider to a trusted ally working in the shadows for the Allied cause.

Luca’s internal conflict and gradual redemption arc add emotional depth to the narrative, illustrating how war disrupts social orders and personal identities. His eventual departure leaves an air of melancholy, symbolizing the heavy costs borne by those who survive.

Jacques

Jacques is a layered figure whose loyalties and intentions remain ambiguous for much of the story. Initially appearing as a charming, worldly friend who provides insight into Lisbon’s refugee crisis, he later emerges as a key figure aiding Jewish families in hiding.

His duplicity—or perceived duplicity—creates tension, as Selene and Bea must constantly weigh their trust in him. Jacques embodies the gray areas of wartime espionage, where survival often necessitates moral compromises and covert alliances.

His involvement in the post-war resettlement efforts suggests a continuity of his commitment beyond mere espionage, adding a hopeful note to his character’s arc.

Colonel Fitzgerald

Colonel Fitzgerald functions as a figure of authority whose true motives are initially obscured. At first perceived as a potential antagonist, his interrogation of Bea and guarded demeanor raise suspicions.

However, it is later revealed that Fitzgerald operates within a complex counterintelligence framework, intentionally maintaining a façade of hostility to protect key operatives. His enigmatic presence underlines the layered nature of wartime intelligence, where deception is not only used against the enemy but also within Allied ranks to safeguard missions.

Fitzgerald’s cryptic warnings to Bea reflect his awareness of the stakes and the delicate balance of trust required.

Dorothy and Nora

Though secondary, Dorothy and Nora enrich the narrative by representing the vulnerable civilians and lesser-known heroes within Lisbon’s wartime community. Dorothy’s arrest and disappearance, linked to her affair with a German sailor, highlight the personal dangers civilians face amid the espionage and occupation.

Nora’s mourning for Dorothy and her quiet resilience reinforce themes of sacrifice and solidarity among women navigating perilous times. They embody the human cost of war beyond the battlefield.

Themes

Loyalty, and Moral Ambiguity in Wartime Espionage

In The Librarians of Lisbon, lies an intricate exploration of how personal identity becomes fragmented and reshaped under the pressures of espionage during war. The protagonists, Selene and Bea, grapple with divided selves as they assume multiple roles—Selene as a glamorous spy infiltrating high society, Bea as a reserved librarian quietly weaving resistance through information.

Their loyalties are perpetually tested, not only to their countries but to each other and themselves. The narrative probes the moral ambiguity inherent in spycraft: seduction, deception, and betrayal become necessary tools, blurring the lines between right and wrong.

This theme underscores how in war, the rigid categories of heroism and villainy dissolve into a spectrum where survival, sacrifice, and pragmatism dictate choices. Selene’s decision to protect Marguerite despite her betrayal exemplifies this layered loyalty, revealing how human empathy complicates the black-and-white narratives of espionage.

The Psychological Toll of Trauma and Loss on Women’s Resilience in a Male-Dominated Warzone

The Librarians of Lisbon delves deeply into the psychological aftermath of war, especially on women who are often sidelined in historical war narratives. Bea’s quiet obsession with finding her fiancé Pete, along with her evolving role from passive librarian to active resistance participant, illustrates the undercurrent of grief and hope that fuels women’s resilience.

Meanwhile, Selene carries the burden of survivor’s guilt and the trauma of past missions, haunted by fallen comrades and near-death encounters. Their struggles reflect broader themes of how trauma shapes identity and motivates acts of courage.

The book emphasizes the emotional labor women endure in male-dominated war environments, portraying their strength not only through physical bravery but through persistence, intellect, and moral courage. The tension between their public facades and private pain provides a poignant insight into the sacrifices hidden beneath the surface of espionage.

The Subversion of Traditional Gender Roles through Female Agency and Espionage

The Librarians of Lisbon challenges and subverts traditional gender expectations by portraying its female protagonists as complex agents of power within a male-dominated socio-political landscape. 

Selene’s use of beauty and charm as weapons disrupts conventional ideas of femininity, transforming what might be perceived as superficial traits into tools of intelligence and influence.

Bea’s transformation from librarian to codebreaker and organizer of clandestine refugee operations further exemplifies this theme. 

The story suggests that women’s agency during war transcends stereotypes; they are not mere victims or bystanders but active participants shaping history behind the scenes.

This theme also raises questions about the cost of such agency—how adopting traditionally masculine tactics of deception and violence conflicts with or reinforces gender norms.

The Ethical Dilemmas and Human Cost of Resistance Movements Within Occupied and Neutral Territories

The narrative explores the ethical complexities faced by resistance operatives working in a neutral yet perilous setting like Lisbon during World War II. Characters confront the harsh reality that every act of resistance carries risks not only to themselves but to innocent civilians and refugees they aim to protect.

Bea’s efforts to smuggle refugees onto ships and Selene’s infiltration of elite circles illustrate the fine line between heroic defiance and endangering lives. Marguerite’s blackmail-induced betrayal highlights the moral quandaries forced upon individuals trapped between loyalty to family and allegiance to the cause.

The book refrains from romanticizing resistance, instead presenting it as a fraught, often tragic endeavor fraught with sacrifices, divided loyalties, and impossible choices. This theme invites reflection on the human cost of war beyond the battlefield—the emotional and ethical weight borne by those who resist in the shadows.

The Enduring Impact of Memory, History, and the Narrativization of Unsung Female Contributions in War

Finally, the novel contemplates how history remembers—or forgets—the contributions of women who operated in the covert theaters of war. The framing device of Selene returning to Lisbon decades later, reflecting on past deeds, underscores the theme of memory’s fragility and power.

The story questions who gets to write history and how female heroism is often relegated to footnotes. Through Selene’s memoir and the characters’ reunion, the narrative affirms the importance of reclaiming and honoring the stories of women who shaped wartime efforts from the margins.

This theme resonates with contemporary conversations about visibility, legacy, and the politics of remembrance, stressing that acknowledging the complexities and sacrifices of such women enriches our understanding of history.
