Yukio Mishima's 'The Sailor Who Fell from Grace with the Sea' is a chilling masterpiece of psychological depth and disturbing beauty. Set in post-war Japan, it tells the story of Fusako, a widowed mother, and her intelligent but troubled teenage son, Noboru. Their quiet lives are disrupted by the arrival of Ryuji, a handsome sailor whom Fusako falls in love with. Noboru, initially idolizing Ryuji for his adventurous spirit, becomes increasingly disillusioned as Ryuji settles into a mundane domestic life. This betrayal of his idealized image drives Noboru and his nihilistic gang of friends to conceive a horrifying plan, exploring themes of innocence, disillusionment, and the dark undercurrents of human desire and societal pressure.
