The Poison Belt is the second story that Doyle wrote about Professor Challenger. Written in 1913, much of it takes place in a single room in Challenger's house in Sussex.In this novella, Challenger sends telegrams asking his three companions from The Lost World (first story about Prof. Challenger) Edward Malone, Lord John Roxton, and Professor Summerlee, to join him at his home, and instructs each of them to bring oxygen.On arrival they are ushered into a sealed room, along with Challenger and his wife. In the course of his researches into various phenomena, Challenger has predicted that the Earth is moving into a belt of poisonous ether which can be a threat to life on Earth. Challenger seals them in the room with cylinders of oxygen, which will counter the effect of the ether until the planet passes through the poison belt.
