Adán Barrera—Raúl Barrera
The Power of the DogAdán Barrera and Raúl Barrera are brothers whose bond is both the foundation of their shared ascent and the relationship most painfully tested by power. Raised together after their father’s death, they enter the criminal world as partners and later become rivals over leadership. Their final crisis turns on a betrayal neither brother initially understands: Raúl’s suspicion of Nora strains his agreement with Adán, and his death leaves Adán to choose how to answer his brother’s last request.
Childhood and Early Partnership
Their father died when Adán was four, and their uncle, Miguel Ángel “Tío” Barrera, took responsibility for raising both boys. Though still young himself, Tío brought money into the household, acted as a father to them, and tried to guide their conduct. As his position in the force improved, the family’s circumstances rose with it. The brothers grew up as city children in Culiacán, attending school and joining social life there, with trips to beach parties in Mazatlán and summers at Tío’s hacienda in Badiraguato.
Those summers gave the brothers a shared attachment to the rural community around the hacienda. They rode bicycles to mountain lakes, swam in the quarries, and spent time on the house’s porch while their aunts cooked for them. Adán came to love the campesinos among whom they played. This childhood sits alongside, rather than outside, the violence that later governs their lives: the boys’ rural visits could be idyllic, but the family’s position and Tío’s work also placed them close to danger.
As young men, the brothers appear together at a boxing gym, where they manage a promising fighter. Adán, not yet twenty, is short and slight, dressed in conspicuously expensive clothes; Raúl is much taller and more powerfully built. Their faces are notably alike despite the contrast in their physiques. When the fighter knocks out his sparring partner and the crowd avoids taking his place, Art Keller steps into the ring. After the match, Adán introduces himself and Raúl, and the two speak as a team committed to the fighter’s future. Raúl recognizes that Art endured the bout rather than quitting, and praises the quality of his fighting. The episode establishes the brothers’ complementary presence: Adán handles the introduction and declares their shared ambition, while Raúl assesses toughness and commands respect through it.
A Shared Rise Under Tío
The brothers’ partnership continues into the period when Tío gathers surviving traffickers after Operation Condor. At a private dinner guarded by armed DFS men, Adán sits beside Raúl and studies the people Tío has chosen to bring together. The brothers are present as members of the same family and as participants in a network whose organization and survival depend on their uncle’s power. Their proximity at the table makes visible the family bond that precedes their later competition for control.
Their closeness does not mean that they are interchangeable. Adán is presented early as observant and composed, a young man who seems to understand what is happening around him. Raúl’s physical presence is more imposing, and his judgments emphasize endurance and force. The boxing encounter makes that difference legible in a small, ordinary setting; later, it acquires greater consequence as their roles in the organization diverge. The brothers have learned the same world under Tío, but they do not respond to authority and violence in identical ways.
Leadership and Suspicion
By the later conflict, Adán’s authority is no longer secure. Raúl is unhappy with the failure of a highly paid intermediary to prevent an attack on Rancho las Bardas or establish whether Nora Hayden had informed against them. He needs an answer quickly, in part because Nora’s connection to Adán makes the question inseparable from the brothers’ personal relationship. Adán is being held in a safe house while Raúl’s men guard him. The shift is stark: brothers who once stood together as young managers now occupy opposing positions within the same household, with one brother controlling the other’s freedom.
Raúl’s suspicion also governs his treatment of Nora. Days of questioning have not established that she betrayed them, and Raúl tells Adán that she has not been physically harmed. Adán makes clear that any harm to her would have consequences, even for his brother. Yet he cannot rule out the possibility that she is the informer. The brothers’ exchange exposes a limit to their loyalty: Adán’s protection of Nora and Raúl’s demand for certainty pull them toward different decisions, while the danger of the investigation makes every concession precarious.
They reach an understanding that depends on the truth about Nora. If she is not the traitor, Raúl will give up the leadership he has assumed and Adán will resume his position. Adán recognizes, however, that a transfer of power is not easily reversed once someone has taken control. Their agreement therefore offers a possible route back to the old arrangement without restoring the trust that arrangement required. It is both a practical bargain and a measure of how far their relationship has changed: each brother needs the other to honor a promise, but neither can make the promise secure.
Raúl’s claim to leadership is tied to his judgment of Adán. He sees his brother as having become soft and too focused on calculation, a criticism that frames their struggle as a disagreement over what kind of leader the organization requires. The book does not reduce their division to simple hatred. Raúl still acts within the terms of brotherhood, and Adán’s concern for him persists even while Raúl holds him under guard. But affection has become entangled with command, suspicion, and the question of who gets to decide what happens next.
The Final Reversal
The crisis resolves when Raúl is wounded during an attack. As his men try to move him, Adán cradles his brother’s head in his lap and insists that Manuel drive them. The urgency leaves Adán with an impossible choice: slowing down would delay help, while moving faster worsens Raúl’s distress. Raúl asks him for something Adán understands without needing it explained. The scene reverses the brothers’ earlier positions. The brother who had held Adán under guard now depends on him, and Adán must act not as a rival claimant but as the person Raúl trusts with his final decision.
Raúl tells Adán that Nora was not responsible; Fabián Martínez was. The revelation answers the question that had divided the brothers, but it arrives too late to restore their agreement or undo the conflict built around it. Adán stops the car, takes Raúl’s pistol, and, at his brother’s request, kills him. The account presents this as an act carried out between brothers at the end of a desperate journey, without turning it into reconciliation by itself. What Adán does is bound to Raúl’s appeal and to the care with which he has carried him; it is also the irreversible end of their shared life.
Meaning of the Bond
The brothers’ relationship traces the cost of passing authority within a family shaped by violence. Their early partnership is grounded in shared upbringing and mutual recognition, while their later conflict grows from the same closeness: Raúl’s suspicion reaches directly into Adán’s private attachments, and Adán’s claim to leadership cannot be separated from Raúl’s challenge to it. Neither brother becomes a stranger to the other, even when one imprisons the other and their competing judgments threaten the family bond.
Their final exchange gives that bond its most consequential form. Adán discovers that Nora was not the betrayer, but the discovery cannot restore the future the brothers had negotiated. Instead, the truth arrives alongside Raúl’s dependence on Adán and his request to end his suffering. The relationship closes not with a settled transfer of power but with Adán carrying out that request. The brothers’ shared history—from childhood under Tío to their joint presence in the organization—culminates in an act that is at once an expression of loyalty and the severing of the relationship that loyalty could no longer save.
