Case Closed Volume Six is a manga by Gosho Aoyama, and it was published in North America by Viz Media in 2005. The series is rated “T+” for older teens; personally, I would agree with this rating.
Teen detective Jimmy Kudo was shrunk back down to his first grade self after being caught by members of a crime organization and being made to take an experimental poison. The crime organization members left him for dead, so they have no idea that he survived.
To protect himself, Jimmy took on the identity of Conan Edogawa and claimed to be a relative of Dr. Agasa. The younger Jimmy goes to live with his friend, Rachel Moore (who is unaware of Conan’s true identity) and her bumbling private investigator father, Richard. As Conan, Jimmy covertly helps Richard solve the cases that come up in the Case Closed series.
There are four mysteries in this volume. The first is a continuation of the last mystery in Volume Five, and the fourth mystery is not resolved at the end of this volume. All of these stories were adapted for the Case Closed anime series.
The first mystery is the resolution of the Conan kidnapping case. If I hadn’t already seen the corresponding anime episode, the resolution of this story would have caught me by surprise.
The second is a murder mystery that takes place while Richard Moore is at the victim’s home, reporting to the victim that his wife has been cheating on him. It turns out that Richard isn’t a suspect, but there are three potential suspects. Conan has to work to figure out who the real murderer is.
The anime adapted this particular story rather faithfully. In the manga, as the reader thinks they’ve figured out who committed the crime, a new piece of evidence is revealed that makes the reader question whether or not they’re actually right. I really liked how Aoyama wrote this particular mystery.
