The final, and certainly climactic, adventure of Sir Arthur Conan Doyles Professor George Edward Challenger is 1928s When the World Screamed. It is another Professor Challenger story where a new craziness pressures him to make the earth feel the existence of human being on its surface.
Professor says the earth is a giant creature and it doesnt even care or know that we the human being exist on its surface. Professor believes that by drilling into the center of the earth, he will be the first person to let the planet know that there are people on its surface.
The majority of the story, like others in the story, is about the build-up to the event. Its narrated by a new character, Peerless Jones, who is an expert on drilling.
