《堕落诗集》创作于1939年,同年3月由新潮社出版,是作者早年的代表作之一。故事描写的是一位警官同女犯邂逅后产生爱情的经过。以沦落为扒手的女犯的抒情诗为线索,记叙了三十年代已进入军国主义的日本社会的一个侧面。是作者独具一格的社会小说,也是日本小说从“私小说”和“心境小说”中解放出来的产物。 “Fallen Poetry” was created in 1939, the same year in March by the New Wave Publishing House, is one of the author’s early masterpiece. The story describes a police officer after the encounter with the woman who had the love after. Taking the lyrics of the women criminals reduced to pickpockets as a clue, I recalled one aspect of the Japanese society that has entered the militarism in the 1930s. Is a unique social novel by the author and a product of the liberation of Japanese novels from “private novels” and “state of mind novels.”
