The story centers on the murder of novelist Kyosuke Moroguchi, found dead in his study from apparent potassium cyanide poisoning.
The Suspects: Three individuals close to the victim—his secretary, wife, and a fellow writer—all have motives, yet none seem to have had the opportunity to administer the poison.
The Red Herring: A significant portion of the case involves cassette tape recorders, which the episode notes were already becoming outdated in favor of digital recorders at the time of airing.
Conan's Dilemma: This episode is a rare moment where Conan hesitates to put Kogoro to sleep. He recalls a previous incident (the Shinkansen Transport Case) where Sato grew suspicious after seeing him "fiddling" with the Sleeping Kogoro’s mouth. The "Love Story" Evolution
What makes this episode "interesting" for many fans is the sub-plot involving a ring on Sato's left ring finger.
The Confusion: Takagi and the rest of the police force are in a panic, assuming Sato has become engaged.
The Reality: It is eventually revealed that Sato is wearing the ring simply to ward off unwanted advances from men, unaware of the romantic significance of that specific finger.
Production Easter Egg: The episode's chief producer, Michihiko Suwa, voiced one of the police detectives in this specific story. Critical Perspective: A Long-Running Legacy
While Episode 487 is praised for its "fluff" and character development, modern video essays often use these middle-era episodes to discuss the show's evolution. Critics sometimes point out that the sheer volume of "case-solving" episodes can lead to repetitive tropes or "filler" feelings, making these character-focused "Police Love Story" arcs essential for keeping long-term viewers engaged.

Detective Conan Episode 487, titled "Metropolitan Police Detective Love Story 8: The Left Hand's Ring Finger", is a standout installment in the long-running Case Closed series. Originally aired on October 15, 2007, this episode masterfully blends the series' signature intricate mystery with the fan-favorite romantic tension between Detectives Miwako Sato and Wataru Takagi. Episode Overview
Title: Metropolitan Police Detective Love Story 8: The Left Hand's Ring Finger Original Air Date: October 15, 2007 Manga Source: File 576–578 (Volume 56) Case Type: Locked-room murder The Romantic Rumor Mill
The episode begins with a buzz at the Metropolitan Police Department. Detective Sato is seen wearing a ring on the ring finger of her left hand—traditionally the finger for engagement rings. This sends shockwaves through the department, particularly among the male officers who are notoriously protective of Sato. Detective Takagi, who did not give her the ring, is left in a state of depressed confusion, wondering if someone else has captured her heart.
It is later revealed that the ring was actually a gift from Yumi Miyamoto, who told Sato it was a "charm" to keep "bugs" (unwanted suitors) away. Sato, being somewhat dense in romantic matters, took the advice literally without realizing the significance of which finger she chose. The Case: The Locked-Room Mystery
While the police department is distracted by office gossip, Kogoro Mouri is invited to an interview with a famous but arrogant mystery writer, Masataka Moroguchi. Moroguchi is obsessed with analog technology and recently acquired a gaudy, diamond-encrusted ring.
The next morning, Moroguchi is found dead from cyanide poisoning in a sealed room. The key to the room is found clutched in his own palm, and the only other opening is a window too small for an adult to pass through. Suspects & Motives Kakuji Dejima: Moroguchi’s interviewer. Wataru Tarumi: An editor. Harue Anabuki: Moroguchi’s housekeeper. The Resolution
Conan Edogawa, naturally, identifies the trick behind the "locked" room. The culprit used a cassette tape string looped around Moroguchi’s ring to create a "zip-line" from the small window to the victim's hand. This allowed the killer to slide the key directly into the deceased man's palm from outside the room.
The murderer is revealed to be Kakuji Dejima, who sought revenge for his friend and former assistant of Moroguchi, Akiba. Moroguchi had used Akiba as a "test subject" for his macabre murder ideas, which eventually led to Akiba's death—a tragedy the police had originally ruled a suicide. Ending and Legacy
The episode concludes with a classic "Takagi and Sato" moment. After Sato realizes the misunderstanding her ring caused, she accepts Takagi's offer to replace the "charm" with a ring of his own choosing—though the romantic progress remains characteristically slow.
For fans, Episode 487 is a perfect example of why the Metropolitan Police Detective Love Story sub-series is so beloved, offering high-stakes deductive reasoning alongside the endearing, comedic development of the series' secondary cast.

This is where Episode 487 digs deep into character psychology. Sato is not just excited; she is terrified. Viewers will recall that Sato’s first love, Detective Jinpei Matsuda, was killed by a bomb set by the serial killer "Kamiya" before they could formalize their relationship. Matsuda died with a ring in his locker that he never got to give her.
Sato begins to see parallels: Takagi is going to a dangerous location (a secluded park) to give her a ring. Her PTSD kicks in. She flashes back to Matsuda’s death, worrying that history is repeating itself. She believes in the "curse" of the police love story—that any officer who finds true happiness will lose it in the line of duty.
By Episode 487, the "Metropolitan Police Love Story" series had already become a beloved sub-franchise within Detective Conan. These episodes focus exclusively on the romantic tension and professional dangers faced by the officers of the Tokyo Metropolitan Police Department (MPD), particularly Miwako Sato and Wataru Takagi.
Episode 487 is the eighth installment of this series. It follows the massive character development from previous episodes (like the infamous "Emergency 100" case) and raises the stakes to an almost unbearable level. The title, "The Left Hand Ring Finger," is a direct reference to the finger traditionally reserved for wedding rings, signaling that this episode is all about commitment and destiny.
While chasing down clues, Takagi suddenly asks Sato to meet him at a specific location that night. He claims he has something important to tell her—something he can only say face-to-face.
Fans of the series know that Takagi is notoriously shy. His hesitation to commit has been a running gag for hundreds of episodes. But here, the atmosphere is different. He holds a small box in his pocket. It is heavily implied (and later confirmed) that Takagi intends to propose marriage.
