Chapter Summaries

After returning from vacation, Lin Xinyi was assigned to investigate the murders of two Tokyo officers who had reopened a suspicious suicide case. The case’s sole suspect was Director Odagiri’s son, and Lin Xinyi took charge of an investigation meant to uncover the truth without favoritism.

• Director Odagiri told Lin Xinyi that Narasawa Haru and Shiba Yoichiro had been shot dead by the same killer.
• Lin Xinyi learned that the victims and Sato Miwako had recently resumed investigating a suicide case from the previous year.
• Director Odagiri revealed that his son, rock singer Odagiri Toshiya, had been the only suspect in that case.
• Director Odagiri appointed Lin Xinyi to lead a secret investigation team with Department Head Asai, Sato, Shiratori, and Takagi.
• Lin Xinyi promised he would arrest even Director Odagiri if the investigation proved his son was the murderer.

Asai Narumi joined Sato Miwako to take over the murders of Senior Nara and Officer Shibayo, while Takagi Wataru and Shiratori Ninzaburo speculated about who Sato liked. Lin Xinyi arrived and mistook Sato’s name, leaving Takagi and Shiratori relieved that he did not seem to recognize her as a romantic interest.

• Asai Narumi told Sato Miwako that he and Lin Xinyi would join the investigation into the murders of Senior Nara and Officer Shibayo, along with Takagi Wataru and Shiratori Ninzaburo.
• Asai explained that he let colleagues call him Miss because the attention often made investigations and requests for backup easier.
• Takagi and Shiratori both rushed to help Sato gather the documents she had dropped, then sat together and discussed their feelings for her.
• Takagi named Shiratori, Inspector Megure, and Lin Xinyi as possible people Sato liked, and Shiratori considered whether she might have feelings for Lin.
• Lin arrived and failed to remember Sato’s name, calling her Sada before Takagi and Shiratori corrected him.

Lin Xinyi took charge of the investigation into two officers’ murders and the suspicious suicide case linked to Director Odagiri’s son, promising to protect his team from pressure. After Sato Miwako recalled her late father’s words and admired Lin Xinyi’s resolve, he reviewed the old case file and angrily accused her of closing an obvious homicide as a suicide.

• Lin Xinyi praised Asai Narumi’s forensic work and said the two officers’ murders offered few leads, so the task force needed to focus on the year-old suicide case.
• Sato Miwako explained that Nino Tamotsu’s supposed motive for suicide was doubtful and revealed that he had publicly clashed with Odagiri Toshiya before his death.
• Shiratori Ninzaburo questioned whether Director Odagiri would truly allow an impartial investigation, and Lin Xinyi vowed to pursue the case regardless of the suspect’s connections.
• Sato Miwako recalled her father’s final words about justice and looked at Lin Xinyi with admiration, unsettling Shiratori Ninzaburo and Takagi Wataru.
• Lin Xinyi examined the old case file, became furious, and demanded to know how Sato Miwako could have classified an obvious homicide as suicide.

Lin Xinyi confronted Sato Miwako over her role in closing Nino Tamotsu’s death as a suicide and used the autopsy report to show why the case was likely a homicide. Sato admitted her mistake, and Lin softened his rebuke to comfort her as Shiratori and Takagi worried she might fall for him.

• Sato Miwako defended the year-old suicide ruling, but Lin Xinyi criticized the investigation and asked Asai Narumi to examine the crime-scene photographs.
• Asai Narumi pointed out that Nino Tamotsu’s hands were bloodless and his neck had no hesitation cuts, despite the supposed suicide.
• Lin Xinyi challenged Sato’s reliance on the autopsy and explained that the wound’s direction, angle, and position below the Adam’s apple strongly suggested homicide.
• Sato Miwako realized she had helped mishandle the case and deeply apologized to Lin Xinyi.
• Lin Xinyi told Sato that action mattered more than bowing, helped her stand, and apologized for assuming she had not tried her best.
• Shiratori Ninzaburo and Takagi grew tense as Lin Xinyi comforted Sato Miwako and suspected she might fall for him.

Lin Xinyi helped Sato Miwako move past her guilt over the wrongful conviction and reopened the investigation into Dr. Nino’s death. After reviewing the case files, he concluded that Odagiri Toshiya probably was not the murderer.

• Lin Xinyi bluntly told Sato Miwako to stop blaming herself and focus on solving the case, and she returned to work with renewed resolve.
• Sato Miwako explained that Odagiri Toshiya had extorted money from Dr. Nino after catching him illegally selling medication.
• Asai Narumi analyzed the neck wound and explained why the murderer might have been left-handed or right-handed, while Odagiri Toshiya was known to be left-handed.
• Sato Miwako said the murderer had taken a scalpel from Dr. Nino’s home, which had helped make the death look like suicide.
• Lin Xinyi studied the crime-scene photographs and concluded that Odagiri Toshiya probably was not the murderer.

Lin Xinyi used the murder weapon and surgical instruments at the scene to show that the killer had medical knowledge, clearing Odagiri Toshiya of suspicion. The investigation was left focused on finding a doctor who had killed Nino Tamotsu.

• Lin Xinyi showed photographs of the murder weapon and the surgical instruments, then took the officers to the Forensics Division to test how they would choose a scalpel.
• Asai Narumi identified the murder weapon as a No. 23 blade with a standard No. 4 handle and realized the killer had selected the correct combination.
• Takagi Wataru argued that the selection might have been luck, but Asai Narumi explained the proper way to attach a scalpel blade using a needle holder.
• Asai Narumi recognized that the killer had also taken a needle holder from the instrument case, and Lin Xinyi concluded that the killer was a doctor like Nino Tamotsu.

Lin Xinyi and the officers focused their investigation on Nino Tamotsu’s former colleagues, but his many enemies left them with a long suspect list. Shiratori invited Lin to his sister’s engagement ceremony, and Lin began to suspect the event might offer a shortcut in the investigation.

• Lin warned Sato Miwako not to jump to conclusions and advised prioritizing left-handed medical staff while continuing to consider other suspects.
• Sato explained that the hospital staff knew about the reopened investigation, so the source of the leak could not narrow down the suspects.
• Sato revealed that the investigators had examined Nino’s former colleagues and found around twenty or thirty people with grudges against him.
• Lin warned Sato to be careful because the murderer might target her after killing Narasawa Haru and Shiba Yoichiro.
• Shiratori invited Lin to his sister Sara’s engagement ceremony, and Lin asked whether Sato and Conan would attend.

Lin Xinyi used the guest list for Shiratori Sara’s engagement ceremony to identify psychiatrist Kazato Kyosuke as a suspect in the police murders and warn that Sato Miwako might be in danger. Kazato was caught planting a bomb at the hotel and confessed, while Shiratori secretly tried to keep his sister from attending.

• Lin Xinyi asked Shiratori Ninzaburo for the engagement ceremony’s guest list after learning that Mouri Ran and Conan were likely to attend.
• The officers found that Kazato Kyosuke, a psychiatrist connected to Nino Tamotsu and murdered officer Shiba Yoichiro, was on the list and made him their prime suspect.
• Sato Miwako arranged surveillance, and the officers caught Kazato disguised as a construction worker while he planted a remote-controlled bomb at Beika Hotel.
• The police seized Kazato’s bomb and gun, and Kazato confessed to the murders of Narasawa Haru and Shiba Yoichiro.
• When the officers asked how Lin had predicted the danger, Shiratori guessed that Mouri Ran was the reason and secretly texted his sister to keep attorney Kisaki Eri from attending.

Lin Xinyi reported that the murder case had been solved and then insisted that Director Odagiri’s son, Odagiri Toshiya, also be arrested for extortion. Director Odagiri approved the arrest, and Lin led a growing group of officers to take Toshiya into custody.

• Lin Xinyi told Director Odagiri that the task force had solved the murder case and described how he had identified the culprit.
• Director Odagiri and his officers discussed Mouri Ran’s supposed bad luck, but Lin dismissed it as coincidence.
• Lin asked that the task force share credit, then said Odagiri Toshiya should be arrested for extorting Dr. Nino.
• Director Odagiri approved the arrest, and Lin proposed using suspicion of murder to pressure Toshiya into confessing to the extortion.
• Shiratori, Sato, Takagi, and other officers joined Lin’s operation after Sato praised his integrity.
• That night, Lin and a platoon of officers surrounded and arrested Odagiri Toshiya at his residence.

After Odagiri Toshiya confessed, Lin Xinyi wrapped up his extortion case and Kazato Kyosuke’s serial murder case, then left the department as his colleagues mistook Sato Miwako’s request for a confession. Shiratori Ninzaburo and Takagi Wataru wondered who Miwako liked, and their suspicions turned toward Asai Narumi when they encountered her outside the restroom.

• Lin Xinyi and his team arrested Odagiri Toshiya, who confessed, and concluded Odagiri’s extortion case and Kazato Kyosuke’s serial murder case.
• Sato Miwako invited Lin Xinyi to celebrate, but Shiratori Ninzaburo tried to steer him home by reminding her that he had a girlfriend.
• Lin Xinyi mentioned that his relationship with Chris had nearly ended before the Water Crystal incident, and Sato ran after him to ask him to teach her.
• Shiratori Ninzaburo and Takagi Wataru mistook Sato’s request for a confession, then learned she had asked Lin to teach her and did not like him romantically.
• Shiratori and Takagi discussed finding out whom Sato liked, agreed to ask Yumi and Asai Narumi, and stopped after passing Asai at the restroom entrance.

At the Shiratori engagement ceremony, Lin Xinyi reunited with his colleagues and encountered the Mouri family, while Shiratori Ninzaburo worried that Mouri Ran’s presence might bring trouble. The gathering continued when Suzuki Sonoko noticed chairman Masuyama Kenzo watching her.

• Shiratori Ninzaburo and Takagi Wataru watched as Asai Narumi and Sato Miwako bonded over makeup, leaving them unable to join the conversation.
• Lin Xinyi arrived without Chris and thought about how Vermouth had agreed to provide blood samples for Haibara Ai’s antidote research.
• Suzuki Sonoko approached Lin Xinyi in an aloof style Vermouth had taught her, and he mistook her for Miyano Shiho at first.
• Mouri Kogoro looked for Chris until Mouri Ran pulled him away, and he and Kisaki Eri began arguing.
• Mouri Ran asked Lin Xinyi why the guests were looking at her strangely, while Shiratori Ninzaburo worried that her presence might invite an incident.
• Suzuki Sonoko asked about an old man watching her, and Shiratori identified him as Hachibishi Motors chairman Masuyama Kenzo.

At the engagement ceremony, Masuyama Kenzo mistook Suzuki Sonoko for the supposedly missing Miyano Shiho and feared she could expose the organization. He fled after she recognized his face, leaving him convinced that the police-filled gathering had trapped him.

• Lin Xinyi and Masuyama Kenzo exchanged a glance without recognizing each other’s identities as organization members.
• Masuyama Kenzo saw Suzuki Sonoko among police officials and suspected she was Miyano Shiho, who might be working with the FBI and Japanese Public Security Bureau.
• Masuyama Kenzo approached Suzuki Sonoko to question her, but she recognized his face and asked whether he had been a friend of her parents.
• Masuyama Kenzo panicked and hurried away before Suzuki Sonoko could remember where she had seen him.
• Suzuki Sonoko recalled that Masuyama Kenzo had attended her sister’s birthday party, while Masuyama Kenzo feared he had been recognized among the police.

Masuyama Kenzo spotted the supposedly dead Sherry at a police reception and called Gin for help, while Haibara Ai tested Lao Baigan on Vermouth. Gin grew suspicious of Lin Xinyi and ordered Pisco to kill the woman he believed might be Miyano Shiho, intending to deal with Pisco himself if necessary.

• Masuyama Kenzo saw Sherry at Beika Hotel, feared she might recognize him, and called Gin to arrange his escape.
• Masuyama Kenzo told Gin that Sherry was with Tokyo Metropolitan Police officials, including Lin Xinyi, and Gin ordered him to stay put while he verified the situation.
• Haibara Ai invited Vermouth to drink Lao Baigan for an experiment, and Vermouth briefly threatened her before agreeing to cooperate.
• Vermouth drank heavily, showed no apparent APTX4869-related changes, and became drunk enough to leave Haibara Ai shaken and covered in lipstick marks.
• Gin reasoned that Sherry and Lin Xinyi appearing together made little sense, then ordered Pisco to kill the woman and went to assist him with his Beretta.

Masuyama Kenzo disguised himself as a cleaner and tried to assassinate the woman he believed was Sherry, only to discover she was Suzuki Sonoko. He knocked her unconscious and fled as two women arrived at the restroom.

• Masuyama Kenzo obeyed Gin’s order to kill Sherry and planned to escape afterward.
• Masuyama Kenzo disguised himself as a cleaner and followed the woman he believed was Sherry into the restroom.
• Masuyama Kenzo choked the woman, but she revealed that she was Suzuki Sonoko.
• Masuyama Kenzo recognized Sonoko and realized that killing her would bring disaster, so he knocked her unconscious and hid her in a stall.
• Masuyama Kenzo hurried out in his cleaner disguise as two women, including Miss Sato, approached the restroom.

Masuyama Kenzo escaped the restroom after disguising himself as a cleaner, but Sato Miwako and Mouri Ran discovered Suzuki Sonoko unconscious and sealed the hotel exits. Masuyama burned his disguise and used the sprinklers to erase evidence, leaving the police to search for him among the guests and officers.

• Masuyama Kenzo passed Mouri Ran and Sato Miwako in his cleaner disguise, but Sato noticed his bucket was clean despite the wet restroom floor.
• Mouri Ran followed the footprints to a stall and found Suzuki Sonoko unconscious, while Sato Miwako ran after Masuyama Kenzo.
• Sato Miwako alerted her colleagues, and police sealed the hotel entrances and exits.
• A fire in the storage room triggered the sprinklers, extinguishing the flames and soaking the hotel.
• Sato Miwako found Masuyama Kenzo's burned uniform and handgun, then deduced he had changed his appearance and hidden among the crowd.
• Mouri Ran realized the sprinkler water had washed away the suspect's footprints and scent, making him difficult to track.

After an assassin tried to kill Suzuki Sonoko at the Beika Hotel, Lin Xinyi used Caesar to identify the culprit despite the crime scene having been thoroughly washed and cleaned. Caesar singled out Masuyama Kenzo, exposing him as the would-be murderer.

• Toshio Odagiri ordered the officers to investigate the attempted murder and keep everyone at the scene.
• Lin Xinyi inspected the restroom and storage room, then realized the sealed room's air might still contain the culprit's scent.
• Lin Xinyi used a scent extractor to collect air from the storage room and prepared the sample for Caesar.
• Caesar eliminated the scents of Lin Xinyi, Mouri Ran, and Sato Miwako before barking at Masuyama Kenzo.
• Lin Xinyi accused Masuyama Kenzo of trying to assassinate Suzuki Sonoko.

Lin Xinyi identified Masuyama Kenzo as a suspect after Caesar tracked his scent, and Suzuki Sonoko’s account of the attacker mentioning “Sherry” and the “Organization” prompted the Public Security Bureau to take over. Masuyama was escorted away, while Lin rejected the Bureau’s offer to assist with confidential investigations, leaving its officials convinced he was trustworthy.

• Caesar barked at Masuyama Kenzo, and Lin Xinyi asked him to cooperate while seeking further evidence.
• Suzuki Sonoko returned with Mouri Ran and said she could not identify the masked attacker, but recalled that he had called her “Sherry” and mentioned the Organization.
• Public Security Bureau officials grew suspicious of Masuyama, and Toshio Odagiri transferred the case to the Bureau and ordered Masuyama escorted to the Tokyo Metropolitan Police Department.
• Lin Xinyi realized that Masuyama was connected to the Organization and worried that he had handed one of its operatives to the authorities.
• Public Security Bureau officials praised Lin and invited him to assist with confidential cases, but he refused, making them trust him even more.

After Masuyama Kenzo was arrested, Lin Xinyi learned that he was Pisco, an Organization executive, and reported the accident to Vermouth and Gin. Both warned Lin Xinyi to stay away from Pisco, and the chapter ended as he spotted an Apache helicopter in the night sky.

• Lin Xinyi reluctantly promised the Public Security Bureau that he might assist with confidential cases, then called Vermouth using her phone, which Haibara Ai had answered.
• Vermouth explained that Masuyama Kenzo was Pisco, an Organization member, and advised Lin Xinyi to report the arrest truthfully to Gin because Pisco had mistaken Suzuki Sonoko for Sherry.
• Vermouth warned Lin Xinyi to keep himself, Mouri, and Conan away from Pisco, who had been loaded into a police car.
• Lin Xinyi called Gin and explained that he had arrested Pisco by accident after Pisco mistook Suzuki Sonoko for Sherry.
• Gin accepted Lin Xinyi's explanation, told him to do nothing and stay away from Pisco, then ended the call.
• Lin Xinyi heard a strange noise from the night sky, looked up, and saw an Apache helicopter.

Gin ordered an Apache attack on Pisco, and the helicopter killed Masuyama Kenzo while Lin Xinyi rescued an injured public security officer. Before dying, Masuyama told Lin Xinyi to keep investigating and seek help from his child, leaving Lin Xinyi uncertain whether to continue opposing the Organization.

• Gin rejected Vodka’s doubts, ordered the attack on Pisco, and the helicopter fired on the police convoy carrying Masuyama Kenzo.
• Masuyama escaped the first rocket, but later blasts badly injured him and the young public security officer who tried to save him.
• Lin Xinyi charged into the rocket attack and carried the injured officer to safety, while Masuyama was left mortally wounded.
• Gin and the others withdrew after Masuyama was struck, and Masuyama told Lin Xinyi that his child would help him and that a promise from Masuyama’s seventieth birthday was due.
• Masuyama died, and Lin Xinyi closed his eyes while wrestling with whether to keep investigating the Organization or protect the people he loved.

After Gin fled the attack on the Beika Hotel, Lin Xinyi returned to the investigation and warned Suzuki Sonoko that a charming stranger had been probing her for information. The stranger was Furuya, who met with Kazami and heard why Kazami trusted Lin, leaving Furuya less suspicious of him.

• Gin confirmed Masuyama Kenzo's death and escaped by helicopter while Lin Xinyi helped injured officers and returned to his forensic duties.
• Furuya questioned Suzuki Sonoko about her changed appearance and Chris, but Lin Xinyi interrupted him and warned Sonoko that he seemed to be fishing for information.
• Furuya entered the police car where Kazami was recovering and scolded him for risking his life to save someone during the attack.
• Furuya explained that Gin had sent him to check for Miyano Shiho after Masuyama mistook Sonoko for her, and he said Miyano Shiho and Miyano Akemi were probably dead.
• Kazami praised Lin Xinyi's police work and thanked him for saving his life, convincing Furuya that Lin seemed reliable.
