429

Ran and Sonoko invite their new classmate, Eisuke Hondou to visit Kogoro. At that moment, a client named Atsushi Misumi asks Kogoro to search for his girlfriend, Ami. Deducing from her last words, they realize Ami is waiting for Misumi at the place where they first met. They are driven by Misumi to Gunma Prefecture where they find Ami in a sealed up car dead. Misumi breaks into the car by using a bat and breaking through the front window and proceeds to open the door by cutting open the tape from the passenger side. They discover that Ami died from carbon monoxide poisoning and conclude it to be suicide. Conan investigates and realizes it was a murder and believes Misumi's to be the murderer. He then continues to investigate in order to find out how Misumi was able to exit the car while the doors were sealed up with gaffer tape. (Source: Wikipedia)
