Avsnitt 633

Conan deduces that Hoshina was stabbed with an umbrella, which fitted the description perfectly. A contraption on the mansion's clock tower set up by the culprit dragged the umbrella away and out of sight when it hit 6:00. The culprit is one of the party guests, Teigo Karube, who had designed this mansion and lost his clock technician friend four years ago . He reveals that the mistress treated the clock technician like trash and even threw away his friend's beloved clock, so he killed her in order to avenge his friend.
