Yasuhiko Nishizawa was born in 1960 in Akashi, Japan. He studied Creative Writing in the United States, before returning to Japan and beginning to write murder mysteries while working as a university assistant and high school lecturer.
Mediocre mystery short stories with realistically awesome female characters and blossoming of young love. But I think I prefer his SF books over these mysteries. (Though I do like how no one can describe the appearances of the main “detective” of this series. We don’t even know his name.)
