Shinichi Kudo is a high-school student who, by using observation and deduction, is good at solving mysteries. While investigating one, he is caught by the criminals that he was watching and forced to take an experimental drug. Leaving him for dead, the criminals disappear. Instead of killing him, however, the drug turns Shinichi into a little kid.
To preserve the illusion of his 'disappearance,' Shinichi adopts a new name based on his favorite author (Arthur Conan Doyle) and becomes Conan Edogawa. Ran, his (actually Shinichi's) childhood friend takes this little boy under her wing and brings him to her home.
Conan now lives at a detective agency run by Ran's father, but his mind is as keen as ever and he continues to solve mysteries... always allowing Ran's father to take all the credit.
As far as everyone's concerned, Conan is just a little kid anyway... even to Ran. This is *extremely* frustrating to Conan since nobody will listen to a 'little boy.' Despite this, Conan has a mission... to find the criminals who did this to him and get the antidote to that drug.

The story revolves around the lives of two rough-and-tumble high-school friends Kato Hiroshi and Nakama Toru, who seemed to make a habit of getting into trouble and starting up fights. In keeping with the spirit of the manga, Toru and Hiroshi sport slicked back 50's style perms and adopted exaggerated swaggers that made them comical and yet also oddly cool. The drama also features an assortment of outlandish characters who sport even weirder fashions and hairdos. To describe the action in this drama, think Fight Club meets The Breakfast Club.

Won the 12th Kodansha Manga Award for general manga in 1988 (shared with Bonobono).
