What episode in Detective Conan featured a boo-triggered hanging? I'm trying to remember what episode it is, but the setting is that the victim is hanged, but still supported by a book-cart/chair with wheels. the victim is forced to hold a heavy vase. when the vase is dropped, due to sweat, Conan and co. arrive at the scene. But when the door is opened, it moves the books that moves the book-cart causing the victim to get hanged?
