氷菓 (角川文庫)
米澤 穂信 上杉 久代


I finished the Koten-bu(classic literature club) series by Honobu Yonezawa .
I'm not a fan of mystery novels, but this series are pretty good.

Honobu Yonezawa always picks up relatively small incidents such as 'who locked the door?', or  'why a certain book is rent on certain days?'. but these initially seemingly trivial matters finally turned out to have surprisingly meaning.

And characters he made are slightly different from ordinary mystery hero or heroin. They are, more or less, hesitate to behave like a detective.For example, Kobato Jotarou, the main character of the other series by Yonezawa, always does NOT try to solve problems around him. Moreover, He wants to live as a syo-shimin(an ordinary citizen) , and believe that running into troubles and trying to resolve it are  unsuitable behavior as sho-shimin.
