Ernie Simon: The Detective Who Walked Away
Character Overview
Ernie Simon is a homicide detective with the Los Angeles Sheriff’s Department who arrives on Catalina Island in the immediate aftermath of the airstrip shooting that leaves Deputy Alton Quigley dead and Deputy Ilsa Ramirez gravely wounded. Michael Connelly introduces him as a seasoned, methodical investigator—known among colleagues as a “tortoise” rather than a “hare”—whose deliberate approach masks sharp instincts honed over years of working violent deaths. He has “shaggy white hair and a paunch that came from too much fast food and a fondness for vodka after work,” a physical description that signals everyman humility but also the accumulated wear of a career spent staring into abysses.
Simon functions as a moral weathervane within the novel’s universe. He represents the professional investigator who still believes the job can produce justice, even as he navigates a department where institutional image routinely trumps truth. His arc is defined not by triumph but by disappearance—an abrupt retirement that occurs offstage and leaves protagonist Jack Stilwell with more questions than answers. Simon is not the hero of Ironwood, but he is the character whose fate most clearly illustrates the novel’s central argument about what happens to honest cops inside a corrupt system.
Plot Role and Narrative Function
Simon’s narrative function is tripartite: he serves as the official investigative lens on the airstrip shooting, a covert ally to Stilwell when department brass shut the sergeant out, and ultimately a symbol of institutional failure when he vanishes from the story.
He first appears in Chapter 3, entering the cramped Catalina substation interview room to debrief Stilwell. His questioning immediately reveals a skeptical intelligence. When Stilwell recounts that Quigley received a tip from a mainland confidential informant about a drug plane flying in from Mexicali, Simon pushes back: the convenience of an informant calling Quigley out of the blue to tip a drop on the very island where Quigley had just been transferred strains credulity. Simon also drops a crucial revelation—Quigley’s transfer to Catalina was not for the reason Quigley told Stilwell, suggesting a hidden disciplinary backstory that will prove central to the murder motive.
From this point forward, Simon operates in two modes. Officially, he conducts the homicide investigation alongside his partner Trestle, returning to Catalina to take measurements at the airstrip and reconstruct the shooting trajectory. Unofficially, he maintains a back channel with Stilwell—using burner phones, speaking in coded language when his partner is nearby, and sharing fragments of information that keep Stilwell from being completely shut out. This dual existence is the source of Simon’s greatest tension: he is trying to solve a cop-killing honestly while his own chain of command erects barriers.
Simon’s plot role culminates in absence. In Chapter 46, Stilwell calls Simon’s office and learns from assistant Dulce Camarena that Simon “retired abruptly on Friday, with no prior notice.” The timing is conspicuous. Simon had been pursuing leads that pointed toward Lieutenant Gavin Lambert and the ammunition manufacturer linked to him. By Chapter 50, Captain Corum confirms the truth obliquely when he tells Stilwell, “Simon retired, and Trestle’s on a cruise to Hawaii. Nothing’s happened to them.” The reassurance is both a brag and a threat—Corum can make problems disappear without killing anyone, but only if the problems accept their own erasure.
Motivations and Traits Shown Through Actions
Simon’s motivations are revealed less through dialogue than through the decisions he makes under pressure. He never gives a speech about why he became a cop or what justice means to him. Instead, Connelly shows him acting.
Methodical professionalism. Simon refuses to record Stilwell’s first account, preferring to let him tell the story informally before committing it to tape. This is not laziness; it is a interviewing technique designed to surface inconsistencies organically. He knows that a witness who rehearses a story twice is more likely to reveal tells the second time through.
Quiet defiance. When Stilwell finds the sniper’s nest in the ironwood tree—evidence Simon’s own team missed—Simon takes the call on a burner phone. “I’m not even supposed to talk to you,” he tells Stilwell, acknowledging Corum’s order. Yet he takes the call anyway, accepts the photos Stilwell offers (allowing Stilwell to say Simon took them), and reciprocates with information about Lambert’s interview. Simon is not a rebel by temperament, but he cannot stomach the alternative of letting evidence die inside a cover-up.
Protective instinct. His warning to Stilwell is blunt: “Be smart and take a step back. For your own good, Stil, step the fuck back.” This is not cowardice speaking. Simon has seen what happens to deputies who challenge the command structure and recognizes that Stilwell is being set up as a potential fall guy. He says it with the resignation of someone who already suspects he himself will not survive this case unscathed.
Resignation as armor. By the time Simon and Trestle depart Catalina on the ferry in Chapter 28, Simon’s demeanor has shifted. He offers Stilwell little more than non-answers about the investigation and maintains a professional distance that feels calibrated for self-preservation. He is not shutting Stilwell out; he is signaling that the official investigation has been compromised and that further candor will help no one.
Chronological Arc
Simon’s journey across the novel traces a descending line from active investigator to disappeared man.
Chapter 3 – First contact. Simon arrives at the substation and conducts the initial debriefing. He is engaged, probing, already suspicious of the tip’s origins. He establishes himself as the investigator Stilwell hopes will find the truth.
Chapter 14 – The Kalas escape. When Stilwell discovers prisoner Kalas has been removed from the jail by men impersonating ICE agents, Simon vows to track him down. This moment positions Simon as still fully committed and still wielding institutional resources.
Chapter 18 – Quigley’s funeral. Simon warns Stilwell that Kalas was never in ICE custody, confirming the escape was orchestrated. He and Stilwell share a moment of mutual concern—both understand the case is spiraling into deeper conspiracy.
Chapter 28 – The airstrip revisit. Simon and Trestle return to Catalina to map positions and search for ballistic evidence. Simon gives Stilwell nothing substantive in public but accepts Stilwell’s covertly gathered evidence over a burner phone. This is the peak of their secret alliance.
Chapter 30 – The sniper’s nest. Stilwell calls Simon to report finding the ironwood tree perch. Simon acknowledges receipt, confirms Lambert’s interview was unproductive, and again warns Stilwell to step back. The conversation is freighted with things unsaid—both men understand that Corum is engineering a cover-up and that Lambert is protected.
Chapter 44 – The unanswered call. Stilwell, having discovered the MIPCO ammunition connection and Lambert’s sniper background, calls Simon to share what he knows. Simon does not answer either his regular phone or the burner. This is the first sign that Simon has lost the battle within the department.
Chapter 46 – The retirement. Dulce Camarena tells Stilwell that Simon retired abruptly on Friday without notice. The absence is so sudden it feels like a disappearance.
Chapter 50 – The confirmation. Corum admits what happened: “Simon retired, and Trestle’s on a cruise to Hawaii.” The pairing of retirement with a Hawaiian cruise—effectively removing both investigators from the case—is Corum’s way of demonstrating his power. Simon’s arc ends not with a confrontation but with an erasure. He is a man who tried to do his job honestly and was professionally disappeared for it.
Key Relationships
Ernie Simon and Jack Stilwell. The relationship is collegial but asymmetrical. Simon holds institutional power; Stilwell holds local knowledge and access. Their alliance is forged in mutual suspicion of the department they both serve. Simon trusts Stilwell enough to accept covert evidence and share fragments of his investigation. Stilwell trusts Simon enough to risk his career by feeding him information. When Simon disappears, Stilwell loses his last ally inside the official investigation, forcing him to go fully off-book.
Ernie Simon and Captain Corum. Though the two men share no direct scenes in the evidence, their relationship is defined by Corum’s power to order Simon’s silence. Corum tells Stilwell that Simon cannot talk to him. Simon acknowledges this to Stilwell: “I’m not even supposed to talk to you. By whose order? You know who.” Simon’s willingness to violate that order—via burner phones and cryptic conversations—reveals a man who obeys Corum’s command in public while quietly sabotaging it in private. Corum ultimately wins when Simon retires, but the fact that Corum must orchestrate that retirement proves Simon was a genuine threat.
Ernie Simon and Trestle. Simon’s partner is hazier in the text, but their pairing is functional. Simon clearly compartmentalizes information from Trestle when speaking to Stilwell, as shown in Chapter 30 when Simon speaks in code—“Hey, baby, how you feeling?”—until Trestle is out of earshot. This suggests Simon does not fully trust his own partner to resist pressure from above.
Key Decisions and Their Consequences
Accepting Stilwell’s covert evidence. Simon could have reported Stilwell’s unauthorized trip to the airstrip. Instead, he accepts the photos of the sniper’s nest and agrees to claim them as his own. This decision binds him to Stilwell in a conspiracy of truth-telling that puts him in direct opposition to Corum. It also gives the investigation momentum—the sniper’s nest findings suggest a planned assassination rather than a botched interdiction, a conclusion that points toward Lambert and the cover-up.
Pursuing Lambert as a suspect. Simon interviews Lambert about Quigley’s CI and the circumstances of Quigley’s transfer. He gets “the same bullshit answer” and asks Corum to apply pressure, which Corum apparently does not do. This decision—to push on a lieutenant with connections to the command structure—likely marks the point where Simon becomes a problem to be managed rather than a detective to be supported.
Not answering Stilwell’s call in Chapter 44. When Stilwell uncovers the MIPCO ammunition link and calls Simon, Simon does not pick up. This may have been Simon’s attempt to distance himself from an investigation he already knew was being killed, or it may have been the moment when Corum’s pressure became explicit. Either way, the silence signals that Simon has lost the internal fight.
Retiring rather than fighting. Simon’s abrupt retirement can be read as surrender, but it may also be a negotiated exit. Corum tells Stilwell, “Nothing’s happened to them”—meaning Simon and Trestle were not fired or prosecuted; they were given off-ramps. Simon took his, possibly to protect his pension, his reputation, or his safety. The consequence for Stilwell, however, is isolation. Without Simon, Stilwell has no official cover and must face Lambert and Corum alone.
Thematic and Symbolic Connections
Simon’s story connects most directly to the novel’s institutional cover-up theme. He is the investigator who tries to work honestly within a system that punishes exactly that. His arc demonstrates that the LASD, as depicted in the novel, is not merely indifferent to truth—it actively suppresses it when truth threatens the reelection prospects of the elected sheriff and the comfort of the command staff. Simon is the canary in the coal mine; his disappearance proves the toxicity of the environment.
Simon also embodies the obsession and justice theme, though he holds it at a cooler temperature than Stilwell. Where Stilwell becomes consumed by the case to the point of endangering his relationship with Tash, Simon approaches it with professional dedication that stops short of self-destruction. His retirement, seen in this light, is a rational response to an unwinnable situation—he chooses his own survival over heroic martyrdom. This contrasts with Stilwell’s decision in Chapter 50 to reject Corum’s offer and call reporter Lionel McKey instead.
The ironwood tree itself—described in Chapter 15 as part of a grove where trees share an underground root system, “hard outside but vulnerable within”—serves as an apt metaphor for Simon. He presents a tough, unflappable exterior. He tells Stilwell he’s “taking all precautions” and uses burner phones with professional ease. But beneath that hardness, he is vulnerable to the very institution he serves. The root system that sustains him is also what poisons him.
Interpretation vs. Explicit Fact
Some elements of Simon’s characterization must be distinguished from what the text explicitly confirms.
Explicit fact: Simon is a methodical homicide detective known as a tortoise. He questions the CI tip’s convenience. He uses burner phones to communicate with Stilwell. He interviews Lambert and gets unsatisfactory answers. He retires abruptly without notice. Corum confirms Simon retired and Trestle is on a cruise.
Interpretation: Simon’s retirement was coerced. Corum’s phrasing—“Nothing’s happened to them”—suggests a deal rather than a voluntary decision. Simon likely realized that continuing the investigation would result in professional destruction and chose to preserve what he could. The alternative reading—that Simon simply gave up—is less consistent with his earlier willingness to violate Corum’s orders.
Simon’s failure to answer Stilwell’s call in Chapter 44 is ambiguous. The text provides no explanation. The most plausible interpretation, consistent with the timeline, is that Corum had already communicated that the investigation was being redirected and Simon was trying to insulate himself and Stilwell from further departmental scrutiny.
Five Book-Specific Questions and Answers
1. Why does Simon tell Stilwell that Quigley’s transfer to Catalina was not for the reason Quigley claimed?
In Chapter 3, Stilwell tells Simon that Quigley said he was transferred because he arrested the sheriff’s nephew for selling cocaine at a West Hollywood nightclub. Simon replies that while the story may be true, “it wasn’t the reason he was transferred out of narcotics.” Simon has access to personnel records or disciplinary files that Stilwell, as a Catalina substation sergeant, cannot see. The real reason—which the novel later suggests involves Quigley’s wife’s affair with Lieutenant Lambert and the consequent divorce filing—would explain why Quigley was sent to a punishment post. Simon’s early revelation plants the seed that will grow into the Lambert motive.
2. Why does Simon use a burner phone to talk to Stilwell?
Simon’s use of a burner phone, confirmed in Chapter 30, is a direct response to Corum’s order that Simon not speak to Stilwell about the investigation. Corum has formally excluded Stilwell, and Simon complies in public but subverts the order in private. The burner phone is Simon’s acknowledgment that their communications are being monitored or could be discovered, and that speaking truth to the excluded sergeant requires operational secrecy. It is a small act of rebellion from a cop who otherwise follows rules.
3. What does Simon learn from his interview with Lambert, and why is it significant?
Simon tells Stilwell in Chapter 30 that Lambert “claimed that Quigley asked for the transfer and specifically said he wanted to go to Catalina.” Simon immediately labels this “bullshit, because nobody asks to go to the Catalina station.” He also says he asked Corum to apply pressure on Lambert but offers nothing further, leaving Stilwell (and the reader) to infer that Corum refused. The significance is twofold: Lambert is lying about a material fact in a murder investigation, and Corum is protecting Lambert from scrutiny. This turns Simon’s attention toward the institutional cover-up and marks the point where the investigation becomes politically dangerous.
4. Why does Simon retire so abruptly, and what does his retirement mean for the investigation?
Simon retires “abruptly on Friday, with no prior notice,” as Dulce Camarena tells Stilwell in Chapter 46. Corum later frames it as a clean exit: “Simon retired, and Trestle’s on a cruise to Hawaii. Nothing’s happened to them.” The most coherent reading is that Corum forced both investigators off the case—Simon through early retirement, Trestle through mandatory leave—because their inquiry was leading to a decorated lieutenant and a politically embarrassing scandal. Simon’s disappearance effectively ends the official homicide investigation into Quigley’s murder. Stilwell is left entirely alone, forced to pursue Lambert off-book and ultimately to expose the conspiracy through a reporter rather than through law enforcement channels.
5. Does Simon betray Stilwell by retiring instead of fighting?
The text does not support a reading of betrayal. Simon repeatedly warned Stilwell to step back and protect himself. He accepted covert evidence and shared his own findings when he was under no obligation to do so. His retirement was likely the least destructive option in a situation where continued resistance would have resulted in formal sanction or termination. Simon preserved his pension and his freedom; Stilwell chose a more confrontational path. The novel presents both choices as understandable responses to an institution that punishes honesty, and does not judge Simon for choosing survival. His earlier actions—taking the burner-phone call, accepting the sniper-nest photos, pushing on Lambert—demonstrate that his retirement was not abandonment but exhaustion of viable options.
