Episode 277: English Teacher vs. Great Western Detective (Part 1)
Scenario: While at the Professor's, Conan recalls his last meeting with the Black Organization. Conan deduces that another Black Organization member must have been at the hotel party. This is when he finally singles out Chris Vineyard as his suspect. Heiji came to Tokyo to help Conan out with the case. Heiji suspects Jodie-sensei of being a possible Black Organization member, and although Conan seems reluctant to this idea, they pay Jodie-sensei a visit at her apartment. They find out here that her full name is "Jodie Saintemillion". After Jodie agrees to go out for a while with Heiji and Conan, the man living next door to Jodie falls dead outside from over 30 stories, coincidentally as the three are outside. After the police arrive, it seems likely that the man committed suicide. However, Conan and Heiji have a different idea.
