Episode 122: The Locked Bathroom Murder Case (Part 2)
Scenario: Maya's fiancé, Kenneth, busts in telling the police he rang the door bell the day before for a date. Conan detects blood above the peephole on the door and tranquilizes Richard, explaining that Maya didn’t commit suicide but was murdered by her sister Mindy. After rendering Maya unconscious with sleeping pills, Mindy dragged Maya in the bathroom and duct taped the door and window, slit Maya's wrist with a straight razor, and simply walked out. After bringing witnesses, Mindy coaxed them to breaking the door down, then twisted the doorknob to make it appear as if they broken through the seal, when in reality, they did not. As evidence, Mindy unintentionally got Maya's blood on her bandanna that transferred over on the door above the peephole when she looked out at Kenneth. Mindy confesses, stating how the victim stole her boyfriend. After a misunderstanding of feelings, Mindy runs to Maya's corpse begging her to wake up but to no avail. After the case, Richard is running up on stage at Yóko Okino's concert and giving her flowers, however this is revealed to be a dream.
Just as it appears the perfect crime has been committed, Detective Takagi returns with news that could show Mina cared more for her sister than anyone realized. When a spot of Mina's blood is also found on the door, it is all the clues Conan needs to prove Masayo murdered her sister.
