Detective Conan Episode 406 May 2026

Yukie couldn’t kill him directly because she needed an alibi. So she tricked him. On the day of his disappearance, she asked him to meet her at the abandoned shrine at 7:30 PM, claiming she had discovered something important about his past. She gave him a bottle of water laced with sleeping pills. He drank it on the way, feeling drowsy.

The episode begins on a peaceful, rainy afternoon. Ran Mouri is cleaning the agency when she notices Conan Edogawa staring out the window, deep in thought. Kogoro Mouri is, as usual, sitting at his desk with a can of beer and a horse racing newspaper, grumbling about his losses. Ran scolds him for being lazy and not having any clients.

Kogoro, intrigued by the mystery of the locket and the disappearance, agrees to take the case. Conan, however, is already suspicious, noticing a slight hesitation in Yukie’s eyes whenever she mentions the locket. Detective Conan Episode 406

Kogoro, Ran, and Conan drive to the area where Keisuke’s car signal was last detected. It is a narrow, winding mountain road surrounded by dense forest. After searching for a while, they spot a dark blue sedan crashed into a ditch off the side of the road. The car is empty, but the doors are unlocked.

Kogoro (via Conan) reveals that the locket is the key piece of evidence. It is not at the crime scene, and when the police search Yukie’s house, they will find it hidden in her jewelry box. Inside, besides Miyuki’s photo, there will be Keisuke’s fingerprints and, more importantly, traces of the sleeping pills from his system that transferred onto the locket when she removed it from his neck.

She then went back to the car, smashed his watch to show 2:15 PM (the time she wanted to fake), took the locket as a trophy, and drove back to the city using a back road. Her alibi was airtight because she had carefully planned the timing—the drive from the mountain to her friend’s house and the supermarket was exactly 90 minutes, which she accounted for by leaving the shrine at 6:00 PM, not 7:30 PM. She had set Keisuke’s car clock forward by 5 hours earlier that morning, so he arrived at the shrine thinking it was 2:15 PM, but it was actually 7:15 PM.

Yukie discovered the truth about the locket one year ago. She found the old photo and recognized her sister. She realized her husband was the man who killed her sister. She pretended not to know, but she began planning her revenge. She gave him a bottle of water laced with sleeping pills

The episode ends with Kogoro waking up, having no memory of the brilliant deduction. Ran is quiet, and Conan looks at a photograph of the Sonodas on their wedding day, wondering how something meant to heal could also destroy.
