Case Closed

A man is murdered during a party and the detective Kudo Shinichi (Jimmy Kudo) is called to solve the case. He reveals that the host is the murderer and solves the case. Shinichi and his friend, Mouri Ran (Rachel Moore) then take a trip to an amusement park. While they are there a man is decapitated during a roller coaster ride. Shinichi reveals the murderer to be the man's ex-girlfriend, Hitomi. He shows that Hitomi used her necklace made of piano wire and a hook in her purse, looped the wire around the victim's neck and hooked the wire onto the roller coaster tracks during the ride. Hitomi explains that the victim broke up with her and she had planned a murder suicide. After solving this case Shinichi follows two suspicious men in black who were also on the roller coaster and watches them make a clandestine deal. Shinichi is attacked from behind by the two men and forced to take a newly developed poison that should kill him.
