Clamp School Detectives, Book 3

It's tough being Nokoru Imonoyama, the smartest kid at a school for geniuses. There's not a lot that can stimulate his mind. So what does he do? Start a detective agency to help damsels in distress! Nokoru's partners are his two best friends and fellow class board members: South Takamura, a master of martial arts, and Akira Ijyuin, detective by day, thief by night. And when Nokoru isn't trying to replace himself with a robot to get out of his paperwork, he's searching for the owner of a lost silk stocking (obviously a damsel of the highest class), investigating an elaborate surveillance system, and recalling the time he made his first real friend during a daring kidnapping escape. -- VIZ Media
