Chapter Summary — “Special Investigation Department”

Key Plot Points and Events

• On August 19, FBI agents James Black, Jodie Starling, and Shuichi Akai face repercussions from the FBI headquarters after concealing their identities and conducting surveillance at Ellie Square’s concert during a murder investigation.
• Ellie complains to the FBI’s new director, who orders all FBI personnel—including undercover agents overseas—to return to the United States for rotation and loyalty examinations using lie detectors. Akai realizes that this policy could expose undercover FBI agents worldwide.
• The next morning, Shiraishi learns that the murder suspect, Ryosuke Kiriyama, still refuses to confess. Although the evidence—bloodstained clothing, the murder weapon, eyewitness testimony, and his arrest at the scene—is strong, Shiraishi worries that the lack of a confession and motive could create problems in court.
• Shiraishi instructs Munakata to hold Kiriyama until the following Wednesday before sending him to the Prosecutor’s Office, unless he continues to remain silent.
• Before Shiraishi can proceed with moving house, Munakata informs him that prosecutors have arrived to take Kiriyama away. They are not ordinary criminal prosecutors but members of the powerful Special Investigation Department.
• Shiraishi deduces that the prosecutors are likely investigating Kiriyama’s connection to the Chikuma Group and National Diet member Kiichiro Saegusa’s slush-fund scandal, rather than the murder itself.
• Shiraishi postpones his move and goes to Beika Police Station. He orders Munakata to retain custody of Kiriyama until he arrives.
• At the station, Shiraishi confronts Prosecutors Egami and Kawashiri. Although they present an arrest warrant, Munakata and Shiraishi argue that it does not justify simply removing a murder suspect from police custody.
• Shiraishi offers a compromise: the Special Investigation Department may question Kiriyama at Beika Police Station, but they cannot immediately take him away.

Character Developments

• Shiraishi remains cautious and procedurally minded, refusing to rely solely on apparently overwhelming evidence when the suspect has not confessed or revealed a motive. He also demonstrates confidence and political awareness when dealing with powerful prosecutors.
• Munakata shows increasing familiarity with Shiraishi’s methods. He boldly delays the prosecutors and protects the station’s jurisdiction rather than surrendering the suspect immediately.
• James Black is forced to deal with the FBI director’s irrational and authoritarian policies. His normally calm demeanor breaks down as he argues with headquarters.
• Jodie Starling reacts with disbelief to the FBI’s proposed loyalty tests, highlighting the absurdity of the situation.
• Shuichi Akai remains focused on the broader implications of the FBI order. He recognizes that mandatory returns to America could unintentionally identify undercover agents.
• Ryosuke Kiriyama becomes more suspicious because of his continued silence. His connection to the Chikuma Group and the political corruption scandal suggests that the murder may conceal a larger secret.
• Egami, Shiraishi’s former University of Tokyo law-school classmate, reveals an antagonistic relationship with him. His sarcastic remarks reflect the professional and personal tension between prosecutors and police.
• Kawashiri, the senior prosecutor in charge, is frustrated when Shiraishi refuses to honor the Special Investigation Department’s request without proper procedure.

Significant Themes

• Institutional power and jurisdiction: The chapter centers on the conflict between the police and the Special Investigation Department over control of a suspect.
• Abuse of authority: The FBI director’s loyalty tests and the prosecutors’ attempt to use an arrest warrant informally both demonstrate institutions exceeding or manipulating normal procedures.
• Caution versus expediency: Shiraishi insists that strong evidence is not enough if the case lacks a confession or motive, emphasizing the importance of building a legally secure case.
• Political corruption: Kiriyama’s employment with the Chikuma Group links the murder investigation to a wider slush-fund scandal involving a national politician.
• Hidden identities and secrecy: The FBI subplot highlights the danger of exposing undercover agents, while Kiriyama’s silence suggests concealed motives and affiliations.
• Professional hierarchy and rivalry: The strained relationship between Shiraishi and Egami reflects the mutual condescension between police officers and prosecutors.

Character Interactions

• James and Jodie discuss the FBI director’s orders, with Jodie expressing disbelief and James explaining the forced return and lie-detector policy.
• Akai joins the discussion to point out the operational danger of identifying undercover FBI personnel.

• Chihiro warns Shiraishi about the danger of confronting the Special Investigation Department, while Shiraishi argues that their independence does not make them untouchable.
• Munakata clashes with Egami over whether the prosecutors can remove Kiriyama from police custody.
• Shiraishi and Egami exchange superficially cordial but clearly hostile greetings, revealing their history as university classmates and rivals.
• Shiraishi challenges Kawashiri’s arrest warrant and prevents the prosecutors from taking Kiriyama away, instead allowing them to question him inside the police station.

• The Special Investigation Department (SID) arrives to interrogate Kiriyama, but the Beika Police Station allows it only within the station due to the lack of an arrest warrant.
• Shiraishi suspects Kiriyama's murder case might be connected to the SID's corruption investigation, possibly involving the Chikuma Group and Councilor Saegusa.
• Fuji and Makotaka, investigating Kiriyama's identity, discover he might be a "phantom employee" of the Chikuma Group, suggesting he's involved in money laundering for Councilor Saegusa.
• The SID's interrogation of Kiriyama yields no results, and they resort to harsh methods and even offer leniency in his murder case if he cooperates, which is against regulations.
• Shiraishi, eavesdropping on the SID's interrogation, learns about their negotiation tactics and becomes suspicious of their intentions.

Key plot points and events

• Kiriyama remains completely silent despite the Special Investigation Department’s attempts to bargain with him. Shiraishi concludes that further interrogation is pointless without new evidence.

• Sakura’s uncle, despite having little money and three children already, willingly agrees to care for her. He tells Shiraishi that an unknown, stern-looking man gave five million yen at the funeral—an exceptionally large condolence gift.
• Shiraishi suspects the mysterious donor may be connected to the political-funds investigation and asks Munakata to have detectives investigate and show the uncle photographs of relevant politicians and associates. He also tells the uncle to keep the money for Sakura’s care.
• The following week, Munakata reports that the donor has been identified: he was a secretary to opposition-party councilor Morohoshi, a political rival of Councilor Saegusa. Shiraishi is puzzled by the opposition’s involvement and wonders whether Morohoshi’s side is connected to Saegusa.

• After three unusually quiet nights, another death occurs in town. Shiraishi goes to a detached house where a spider expert has died after being bitten by a redback black widow.
• The Junior Detective League is at the scene. Shiraishi confirms they are safe and learns the spiders were kept in sealed enclosures.

Character developments and interactions

• Kanzaki carefully raises doubts about the cause of death, while Shiraishi supports pursuing an autopsy if the family agrees.

Significant themes

• Appearances and mistaken assumptions: A death that looks like a spider accident may conceal foul play; Shiraishi also misunderstands Egami’s personality.

Key plot points and events

• Shiraishi reviews crime-scene photos from the death of spider keeper Kuwashima. Most of the victim’s spiders were tarantulas, which are generally docile and unlikely to cause a fatal bite. The deadly spider was a Sydney funnel-web: smaller, hairless, and highly aggressive.
• The victim was sober and had taken no medication, making it unlikely that he accidentally confused the dangerous spider with his docile pets. The bite’s location on his palm also suggests deliberate handling or feeding.
• Unable to revisit the scene immediately, Shiraishi reconstructs it in his mind using the photos and the layout of Misumi’s apartment. His murmured observation that this was where the spiders “mated” alarms Misumi and Ayako, but he is referring to the reconstructed crime scene—not Misumi’s bed.
• Ayako arrives with cake. After Misumi explains the case, Ayako recognizes that Shiraishi’s intense focus means he suspects foul play.
• Shiraishi says he has identified a possible flaw in the killer’s method, but has not settled on the killer’s identity. He plans to visit the victim’s family at their confectionery shop, Kameya, the next day, with Misumi and possibly Ayako.
• Furusawa, who wanted to enter the house, and Kuwashima’s wife remain possible suspects. Shiraishi intends to learn more from the wife and inspect the house.
• Conan, frustrated that Shiraishi is ahead of him and will not invite him along, decides to visit Kameya on his own.

Character developments

• Shiraishi methodically connects the spider species, the bite, and the victim’s behavior. He has a strong lead but remains cautious about naming a culprit.
• Misumi contributes forensic observations, though she is distracted by Ayako’s arrival and embarrassed by Shiraishi’s misleading remark. Her persistence in pursuing the case is praised.
• Ayako is supportive and perceptive: she understands that Shiraishi’s behavior signals a breakthrough and helps smooth over the awkward misunderstanding.
• Conan contributes a plausible alternative suspect and remains competitive with Shiraishi. His determination leads him to plan his own investigation.

Significant themes

• Careful observation and scientific knowledge: Distinguishing among spider species changes the interpretation of the death.
• Uncertainty in investigation: Shiraishi has a theory about the method, but multiple suspects remain.
• Persistence and deduction: Misumi’s refusal to abandon the case and Shiraishi’s reconstruction move the investigation forward.

• Yuji’s mother-in-law shows Shiraishi a photograph of him tending his spiders, found with a note threatening to expose his hobby. She worries that the scandal could damage the century-old family business.
• Yuji’s widow, Mika, says she knows who sent the message: Kogure, a spider dealer who sold Yuji expensive spiders and is now seeking to take them. Mika plans to let him collect them that evening, despite her dislike of spiders.
• Shiraishi arranges to be present when Kogure arrives. Conan later joins the group on his own, having learned about the meeting.
• Kogure arrives with crickets to feed the spiders, explaining that they have been hungry for over a week and must eat before he can safely transport them the next day. He also insists that carbon-dioxide anesthesia can kill their legs, recalling that Yuji stopped using it after his warning.

Character developments and interactions

• Shiraishi takes charge of the visit and keeps a watchful eye on Kogure, while using the planned spider collection as an opportunity to inspect the scene. His close rapport with Misumi and Ayako creates awkward misunderstandings for Mika.
• Misumi is embarrassed that the autopsy yielded few new findings and remains visibly uneasy around spiders, but still asks about their fate.
• Mika is caught between her mother-in-law’s hostility and her own complicated feelings about Yuji’s hobby. Though she dislikes spiders, she resents Kogure more for exploiting her husband’s interest and the family’s situation.
• Yuji’s mother openly criticizes Mika and condemns Yuji’s spider-keeping as shameful, revealing the tension in their relationship.
• Kogure appears nervous around Shiraishi but seems genuinely concerned about the spiders’ welfare, complicating his apparent blackmailing and opportunism.
• Conan arrives alone and shows his usual eagerness to follow the case.

Significant themes

• Reputation versus compassion: The family worries about protecting Kameya’s image, while Mika ultimately refuses to punish the spiders for their role in Yuji’s death.
