"Suuri arvoitus" by Jack London is a novel published in 1915. A university professor imprisoned in San Quentin endures brutal torture through a canvas jacket designed to break his spirit. He discovers an extraordinary escape: entering trance states where he walks among the stars and experiences fragments of past lives across different ages and cultures. Based on real prison torture methods and interviews with former convict Ed Morrell, the story blends mysticism, reincarnation, and science fiction into a tale of survival and transcendence.
