The War of the Worlds (1898), by H. G. Wells, is an early science-fiction novel which describes an invasion of England by aliens from Mars. It is one of the earliest and best-known depictions of an alien invasion of Earth and has influenced many others, as well as spawning several films, radio dramas, comic-book adaptations, and a television series based on the story.
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender, Thorne searches the bulletins for a reported death that matches the photograph. Then another picture arrives.
