Detective Conan (1996)

Season 1: Episode 700

In the cabin, Ayumi suddenly passes out due to a lack of oxygen. Suddenly, a woman appears with an ax and breaks the door down. Meanwhile, Conan and Sera discover the true meaning of the victim's dying message. The culprit was a man named Usagi who was claustrophobic who accidentally killed her. Afterward, Conan and Sera race to the burning cabin only to discover that Ayumi, Genta, and Mitsuhiko were safe because of a "beautiful woman." Conan figures that the "beautiful woman" was Haibara who took the antidote of APTX4869 and wore the deceased woman's clothes in order to save everybody. She tells them a lie in order to hide the fact that she was Haibara, returned in her normal state. However, Mitsuhiko had secretly taken a video of her and sent it to the Detective Agency. There, a waiter at the café below the agency sees the video and so does Subaru Okiya, while drinking Bourbon whiskey.
