"Le vagabond des étoiles" by Jack London is a novel published in 1915. Professor Darrel Standing awaits execution in California's Folsom Prison, where he has endured years in solitary confinement and torture by straitjacket. Through self-hypnosis, he escapes his unbearable reality by experiencing past lives—as a French count, a Dutch sailor, a Viking warrior, and more. This work blends stark prison realism with fantastical journeys through time, serving as both a fierce denunciation of America's brutal prison system and a testament to human imagination's power to transcend suffering.
