Clash of Red and Black! (Hades) Conan's investigation leads him to realize how Kakuzō and Tango's murder was accomplished. Conan tranquilizes Kogoro and impersonates him with the voice changing bow tie to reveal that Kikuyo Tabata, the maid, is the murderer. He reveals Kikuyo served Kakuzō coffee laced with sleeping pills, thus causing Kakuzō to fall asleep. She then set up the scene by placing Kakuzō on top of a trolley and placing a glued noose around his neck. After setting up a line of books leading from the door to the trolley Kikuyo placed a vase in Kakuzō's hand, warning him that if the vase dropped and broke, it would cause people to investigate the noise. When that happened, they would open the door to Kakuzō's room and subsequently move the line of books which would cause the trolley to roll out from beneath him and result in his death...
