This creates an impossible situation. How could a murderer enter, kill the victim, and exit a room locked with a chain latch? Inspector Megure and the police are stumped. This is where the engine of the episode kicks into gear. Usually, Kogoro would fumble around before being knocked out by Conan’s stun-gun watch. However, with Eri present, the dynamic shifts.

Eri Kisaki is instantly characterized as the antithesis of Kogoro. Where Kogoro is brash, often intoxicated, and prone to leaping to conclusions, Eri is composed, sharp, and analytical. Her introduction sets the stage for one of the series' most enduring relationships: the battle of wits between the Lawyer and the Detective.

The mystery in Episode 65 is a "Howdunit" rather than a "Whodunit." The victim is a wealthy and somewhat arrogant member of the study group. The setting is Eri’s high-rise apartment.

In the sprawling, decades-long history of Detective Conan (Case Closed), there are episodes that advance the main plot involving the Black Organization, episodes that develop the romantic subplots, and episodes that stand alone as brilliant exercises in deduction.

Airing in 1997 as part of the Season 3 lineup, this episode marks a significant milestone. It is the first case to feature Eri Kisaki, Ran’s mother and Kogoro’s estranged wife, not just as a guest character, but as a professional rival to the sleeping detective. For fans of the series, Episode 65 is a masterclass in how to integrate character drama with a locked-room mystery.

What makes the reveal special is Conan’s method of delivery. In many episodes, Conan uses the voice-changing bowtie to impersonate Kogoro (Sleeping Kogoro). In this episode, the presence of Eri complicates things. The resolution sees a convergence of efforts: Conan figures it out, but the spotlight must be shared.

Perhaps the most enduring aspect of Detective Conan Episode 65 is the exploration of Kogoro and Eri’s relationship. Up until this point, Kogoro was largely portrayed as a somewhat buffoonish figure—a drunk and a letch. This episode adds layers to his character.

The premise is simple yet effective. Ran, worried about her mother’s living situation (she lives alone in an apartment), drags Conan and a reluctant Kogoro to visit her. The visit coincides with a high-stakes reunion Eri is hosting for a study group from her university days. This setup provides the classic "closed circle" of suspects—a staple of the Golden Age of Detective Fiction.
