The Good Samaritan

Ryan Smith functions as a co-protagonist and Laura’s primary antagonist. The narrative introduces him as a grieving widower whose pregnant wife, Charlotte, has died in an apparent suicide pact with a stranger. His initial characterization is that of a victim struggling to comprehend his loss and tormented by unanswered questions. His arc thus involves a transformation from this state of grief into a determined and vengeful investigator. The discovery of Charlotte’s hidden research into suicide and her frequent calls to the End of the Line helpline provides him with a target for his anger and a purpose for his pain: to find the person he believes manipulated his wife into ending her life.

Ryan’s development is central to the theme of The Blurred Line Between Victim and Perpetrator. In his quest for revenge, he adopts the very methods of manipulation and deceit that he seeks to expose. He creates the detailed persona of “Steven,” a man with severe depression, to infiltrate the End of the Line network and find the volunteer responsible for Charlotte’s death. This calculated deception mirrors Laura’s own tactics, as he learns to play the part of a vulnerable caller, weaponizing his real despair to gain Laura’s trust. His single-minded pursuit of Laura results in further moral compromise when he uses Laura’s 14-year-old daughter, Effie, as a pawn, manipulating her academic and social life to draw Laura out into the open. This willingness to harm a teenager marks the completion of his transformation from a righteous avenger to a perpetrator of cruelty.

Ultimately, Ryan’s character serves as a study in the corrosive nature of vengeance. While his initial motivations are understandable, his actions become increasingly destructive, demonstrating that the pursuit of justice can be as damaging as the original crime. His interactions with Laura are a complex game of cat-and-mouse in which each tries to outmaneuver the other through psychological warfare. The house he bought for Charlotte as a surprise becomes a symbol of his shattered dreams and the location for his planned confrontation with Laura, a space meant for family that he transforms into a stage for revenge. He is a round and dynamic character whose descent is framed as tragic, as his inability to let go of his grief leads him down a path that not only fails to bring him peace but also results in further violence and his own eventual destruction.

Tony Morris is Laura’s husband and a pivotal secondary character whose actions and knowledge drive the central domestic conflict. He is initially portrayed as distant and emotionally unavailable to Laura, but the reasons for (and extent of) this coldness do not become clear until late in the novel: Finding and reading her old social services file, which documented Laura’s pattern of “sociopathic” behavior, shattered his perception of the woman he married, creating a chasm between them that the fire Laura started ultimately solidified. His primary motivation at that point became the protection of his daughters, Effie and Alice, from Laura’s destructive influence, leading him to separate from her and keep the children away.

Tony is thus a man trapped between his duty to his children and the dangerous secret of his wife’s true nature: “I know about you, Laura,” he tells her, “I know what you are and what you’ve done. […] I know everything” (76). This statement encapsulates the foundation of their broken relationship, but it is also ironic: Tony recognizes Laura’s manipulativeness but remains somewhat susceptible to it.

It is this, combined with the fact that he remains financially and emotionally entangled with her, that makes Tony ultimately unable to escape his wife’s control. His affair with Janine Thomson, Laura’s boss, is an attempt to find normalcy and escape, but it only serves to further enrage Laura and draw him deeper into her machinations. When Laura stages an attack on herself, he is drawn back to her side, and amid a confrontation with Ryan’s brother, Johnny, she expertly plays on Tony’s protective instincts. His fatal assault on Johnny, whom he mistakes for Ryan, is the culmination of Laura’s control, as she blackmails him into returning to the family home, trapping him completely. Tony is a round and static character; while his circumstances change, his fundamental fear of Laura and his desire to protect his children remain constant, making him a tragic figure who is both a victim and an enabler of Laura.

Effie Morris is the 14-year-old daughter of Laura and Tony, a character who evolves from a rebellious teenager into a key pawn and, eventually, an antagonist in her own right. Initially, Effie is characterized by her growing independence, her focus on social status, and her secret online flirtations. She is insecure and seeks validation, making her vulnerable to manipulation. Ryan exploits this vulnerability by systematically undermining her academic confidence and social standing at school, framing her as unintelligent and unpopular. This psychological torment serves its purpose, as Effie turns to Ryan, her teacher, for support, creating the very situation of inappropriate closeness that Ryan uses to bait Laura.

Effie’s role shifts dramatically when her mother re-enters her life. Believing Ryan has betrayed her, Effie participates in Laura’s plan for revenge. Laura manipulates Effie’s feelings of humiliation, convincing her to lie about Ryan making sexual advances and to plant pornographic images on his school computer. However, when Laura’s scheme results in public humiliation for Effie, her loyalty dissolves into a desire for retribution against her mother. The novel’s Epilogue reveals that Effie has secretly obtained recordings of Laura’s incriminating conversations with Ryan. Now equipped with the means to destroy her mother, Effie begins her own calculated game of psychological torment, sending anonymous emails and threatening to expose Laura. Effie’s transformation from victim to perpetrator shows her to be a true product of her mother’s influence, “cut from the same cloth” (334), thus perpetuating the cycle of manipulation and control that defines the narrative.

Nate, whose first name is David, is an unhoused man whose life is inextricably linked to Laura’s past. As Laura remembers him, he was in foster care alongside her, acting as Laura’s protector by killing their abusive foster mother, Sylvia Hughes, to save Laura from being sold to a visitor. However, case notes later reveal that Nate was Sylvia’s biological son, a boy with an intellectual disability whom Laura bullied and manipulated into murdering his mother. This act landed him in a young offender institution and then prison, setting his life on a path of self-destruction fueled by addiction.

Nate is a static and flat character, a tragic figure defined entirely by his past and his connection to Laura. For Laura, however, Nate serves multiple psychological functions. Having rewritten their shared past, she absolves herself of guilt and even transforms him into her first “anchor,” a figure of loyalty and protection. At the same time, her efforts to help him imply that some part of her recognizes the truth and feels obliged to make it up to him—not necessarily for his sake, but to maintain her self-image as a good person. This culminates in her “help” engineering his suicide, a microcosm of her broader rationalization of shepherding people to their deaths; Laura implies that Nate asked to die with her, but because she “couldn’t leave Henry” (360), she arranged for him to die alongside Charlotte instead. Afterward, she recast this episode as well, splitting Nate into two distinct people: “David,” a random caller to the End of the Line hotline, and Nate, whom Laura believes died in a drowning accident several months later. Nate’s entire life thus becomes a central example of Laura’s tendency to rewrite reality to excuse her own behavior.

Janine Thomson is Laura’s manager at the End of the Line branch and serves as a minor antagonist and foil. Characterized by her unprofessionalism, including a gambling addiction and a transparent dislike for Laura, Janine is ambitious and resentful of Laura’s popularity and fundraising success. Her affair with Tony positions her as Laura’s direct rival not just at work but in her domestic life as well. Although she correctly suspects Laura’s manipulative nature, her motivations for exposing her are selfish rather than altruistic. When Ryan provides her with damning evidence of Laura’s actions, Janine attempts to use it as leverage to force Laura out of Tony’s life permanently. This decision proves fatal, as she underestimates Laura’s ruthlessness and becomes her victim, bludgeoned to death with a hammer. Janine’s character highlights the dangerous environment of the office, where personal rivalries and secrets fester beneath a veneer of charitable work.
