Episode 143 is a fan-favorite "Gourmet Mystery." Conan, Kogoro, and Ran visit a restaurant in the mountains famous for its curry. The peace is shattered when the restaurant owner’s brother-in-law is found dead in the kitchen—with his head inside a pot of curry.
The twist? The victim had a severe allergy to onions, yet the curry was full of them. The alibis are tight, the snow traps everyone inside, and it is up to Conan (using the "Sleeping Kogoro" voice) to figure out how a simple bowl of rice and curry became a murder weapon.
The episode begins innocently enough with the Junior Detective League excited about an upcoming meteor shower. Professor Agasa treats the kids to a trip to an observatory, hoping to spark their interest in science. However, as is typical in the world of Detective Conan, a peaceful outing quickly turns into a murder investigation.
Upon arriving at the home of an astronomer to borrow a special telescope, the group discovers the astronomer dead at the bottom of a cliff. The police initially suspect a tragic accident, but Conan notices subtle inconsistencies at the crime scene.
Things get complicated when Toru Araile (a college student and fellow detective who is actually a persona used by the FBI's Shuichi Akai to infiltrate the Organization) appears on the scene. Araile attempts to solve the case to maintain his cover, but Conan realizes he must solve it first—without revealing his true intelligence to Araile—to ensure the culprit is caught.
In an era where modern Detective Conan focuses on action and spy-thriller plots, Episode 143 reminds us why the show started as a horror-tinged mystery.
