Professor Challenger #2 • Arthur Conan Doyle
A poisonous ether chokes the world, forcing one scientist to confront humanity's fragile mortality.
When a seemingly inexplicable and invisible menace descends upon the Earth, the indomitable Professor Challenger and a small circle of companions must confront a global crisis that tests both scientific bravado and human endurance. Doyle propels readers through tense, atmospheric scenes of speculation and survival, where curiosity, fear, and moral questions collide as civilization’s comforts thin to their essentials. Part adventure, part philosophical thought experiment, The Poison Belt crackles with suspense and wonder, inviting you to consider how courage, friendship, and reason hold up when the familiar laws of the world begin to tremble.
