Legacy of Evil in Return of the Spider: How Gary Soneji’s Study of Serial Killers Creates a Copycat Chain

Defining the Thematic Claim: Evil as an Inherited Blueprint

In Return of the Spider, the legacy of evil operates as a self-replicating system: violent criminals study and emulate historical killers, passing destructive knowledge forward like a dark apprenticeship. Gary Soneji does not murder in a vacuum—he deliberately researches the “masters of murder” (Son of Sam, Boston Strangler, and others) to perfect his craft. This thematic claim asserts that evil is not born anew with each perpetrator but is learned, refined, and eventually surpassed, creating a chain that ensnares both the guilty and the innocent. The detectives who hunt Soneji—Alex Cross and John Sampson—discover that their own past actions have unwittingly contributed to this legacy, forcing them to confront the uncomfortable truth that justice can become twisted when it collides with a copied, escalating evil.

Tracing the Legacy Across the Plot

1. The Secret Room and the “Profiles in Homicidal Genius”

Early in the investigation, Cross and Sampson enter a hidden room beneath a cabin in the Pine Barrens—a space Gary Soneji built to house his study of serial killers. On shelves sit plastic bins labeled with initials: SOS (Son of Sam, David Berkowitz), NS (Boston Strangler, Albert DeSalvo), ZK (unknown), and others. Above them, a black notebook titled “Profiles in Homicidal Genius” contains Soneji’s handwritten philosophy: “Study the masters of murder.” The chapter outline confirms that Cross finds weapons tagged with the same initials, including a Bulldog revolver marked SOS and a length of white nylon rope labeled TBS (likely for the Boston Strangler). This scene establishes the legacy of evil as a deliberate curriculum—Soneji treats homicide as an art form, copying techniques, collecting trophies, and planning future crimes based on past killers’ successes and failures. The spider web symbol appears here implicitly: the room is a web where each strand connects a historical monster to a new practitioner.

2. Framing the Innocent: How Studied Evil Corrupts Justice

The legacy extends beyond direct copycat murders to the corruption of due process. Soneji plants evidence in a white panel van to frame ex-convicts Eamon Diggs and Harold Beech for crimes he himself committed. He uses knowledge gained from reading police manuals (as shown in the university library scene) to stage crime scenes, knowing exactly what forensic details will mislead detectives. The outline reveals that Diggs dies in prison proclaiming his innocence, and years later, Cross and Sampson must free Beech after discovering exculpatory evidence hidden in Soneji’s journal. This thread demonstrates how the legacy of evil operates indirectly: Soneji’s study of homicide investigation allows him to weaponize the justice system itself. Cross’s own career—built on putting away violent criminals—is shaken when he realizes he helped condemn an innocent man. The Bulldog revolver left in the van, marked SOS, is a direct link to Berkowitz’s .44-caliber weapon, showing how Soneji blends historical symbol with contemporary manipulation.

3. Becoming the Monster: Beyond the Masters

The final arc shows Soneji declaring independence from his teachers. After murdering a woman named Cynthia Owens by strangling her with a rope (a method he studied from the Boston Strangler), he mutters, “Let them study me now.” Earlier, in Chapter 87, he kills an infant—a boundary none of the historical killers he studied had crossed—and declares, “He was his own monster now.” This moment marks a shift from imitation to original evil, yet it remains a legacy because it is built on the foundation of those who came before. The rope itself becomes a symbol of the intimate, hands-on violence that Soneji perfects from DeSalvo’s playbook but then claims as his own signature. Cross, investigating this string of crimes, realizes that Soneji’s evolution means the legacy of evil is not static; each generation can amplify and surpass the last, making the detective’s task increasingly difficult.

Character and Symbol Connections

Alex Cross and the Burden of His Own Legacy

Cross is not merely an observer of Soneji’s legacy—he is caught in its web. The discovery that he helped convict Harold Beech forces him to question his entire career. In a conversation with Nana Mama, he nearly quits, feeling that his detective work “was built on lies.” Nana Mama insists he was “born to right wrongs, including his own,” and he recommits to justice with renewed humility. Her words function as a counterweight to Soneji’s legacy: love and moral guidance can interrupt the chain of evil. Similarly, Bree Cross and Chief George Pittman represent the institutional structures that must adapt when confronted with a copycat-like threat.

Symbols as Links in the Chain

The white panel van is Soneji’s tool for framing Diggs—it physically carries his planted evidence and remains in the Pine Barrens shed, a silent witness to the false conviction. The spider web, though not explicitly named in the evidence, is encoded in the way Soneji entangles multiple killers’ legacies; his secret room is a literal web of trophies and notebooks. The Bulldog revolver, labeled SOS, is a direct homage to Berkowitz, and its presence in the van binds the historical killer to Soneji’s crime. The rope, used for strangulation, connects Soneji to DeSalvo and later becomes a tool of his own signature violence. Each symbol is both a tribute and a stepping stone in the legacy of evil.

Complexity and Contradiction

The theme refuses simple condemnation of Soneji alone. While Soneji is clearly guilty, the novel forces readers to see that the systems meant to stop him—policing, forensics, incarceration—can also be manipulated into perpetuating evil. Cross and Sampson’s earlier mistake in convicting Diggs and Beech stems from good-faith investigation, yet it produces catastrophic results. Furthermore, Soneji’s claim to originality is undermined: even as he proclaims himself “his own monster,” he continues to use the methods of those he studied. The legacy of evil is thus both linear (passed from killer to killer) and cyclical (returning to haunt its pursuers). The contradiction lies in Soneji’s belief that he has broken free, when in truth he has only deepened the pattern. Cross, by acknowledging his errors and choosing to continue his work, offers a different legacy—one of accountability and redemption.

Study Questions

1. How does Soneji’s secret room and notebook illustrate the “legacy of evil” as a transferable curriculum?
   Answer: The room contains bins and notebooks labeled with initials of historical serial killers (e.g., SOS for Son of Sam, NS for Boston Strangler). Soneji writes that one should “study the masters” of murder, treating homicide as an art form. This shows that evil is learned and refined through deliberate study, not spontaneously generated.

2. What role does the wrongful conviction of Harold Beech play in the theme?
   Answer: It demonstrates that Soneji’s knowledge of police procedures, gained from studying homicide investigation manuals, allows him to frame innocent men. The legacy of evil thus corrupts the justice system itself, forcing Alex Cross to confront his own complicity in a false verdict.

3. How does Soneji’s declaration “Let them study me now” represent a turning point in the legacy of evil?
   Answer: It marks a shift from imitation to self-defined mastery. Soneji believes he has surpassed the killers he emulated, yet he still uses their techniques (e.g., strangulation from the Boston Strangler). The legacy continues even as the individual claims originality.

4. In what ways does Alex Cross’s guilt over Eamon Diggs contradict the theme of inevitable evil?
   Answer: Cross’s guilt shows that the legacy of evil is not deterministic; human error and institutional failure play a part. By choosing to free Beech and recommit to justice, Cross interrupts the chain, suggesting that legacies can be broken through accountability.

5. How do the symbols (white panel van, Bulldog revolver, rope) function as carriers of the legacy?
   Answer: The van is used to plant evidence linking Diggs to Soneji’s crimes; the Bulldog revolver, marked SOS, connects Soneji to Berkowitz; the rope ties him to DeSalvo’s method. Each object physically transmits the influence of past killers into the present, making the legacy tangible and traceable.
