After locating Hatsunosuke (Izumisawa Yuki), who had escaped from the scene of Gokuda's (Kondo Yoshimasa) murder, Taro (Hamada Gaku) and Saburo (Kusakari Masao) are foiled in their pursuit when Hatsunosuke vanishes into the car of Sumeragi (Onoe Kikunosuke). Days later, Junji (Morimoto Shintaro) breaks the news of Hatsunosuke's demise, leaving Taro grief-stricken. But soon after, Saburo tells Taro that he has discovered the culprit's hideout and says, "Come if you can handle the poison. If you wish to see the dream of a detective, that is." The showdown draws near.
