Seicho Matsumoto was born in 1909 in Fukuoka, Japan. Self-educated, Matsumoto published his first book when he was forty years old and he quickly established himself as a master of crime fiction. His exploration of human psychology and Japanese post-war malaise, coupled with the creation of twisting, dark mysteries, made him one of the most acclaimed and best-selling writers in Japan. He received the prestigious Akutagawa Literary Prize in 1950 and the Kikuchi Kan Prize in 1970. He died in 1992.
