Professor Challenger

Professor Challenger imperiously summons his three best friends to come this country house, each one to bring a cylinder of pure oxygen. When they arrive, the reason for this strange request becomes terrifying clear. Professor Challenger has become convinced that the earth is entering a poison belt of ether and that life upon this planet is doomed.

'You will conceive a bunch of grapes,' said he, 'which are covered by some infinitesimal but noxious bacillus. The gardener passes it through a disinfecting medium. It may be that he desires his grapes to be cleaner. It may be that he needs space to breed some fresh bacillus less noxious than the last.'

What would you do if you had discovered that the planet was about to be engulfed in a belt of poisonous "ether" from outer space? Professor Challenger invites a hand-picked crew of adventurers and scientists to his home outside London, which has been fortified with several hours' worth of oxygen. Challenger & Co. assemble in front of a picture window to witness the end of all life on the planet.

The Land of Mist is a novel written by Arthur Conan Doyle in 1926. Although this is a Professor Challenger story, it centres more on his daughter Enid and her colleague. Heavily influenced by Doyle’s growing belief in Spiritualism after the death of his son, brother, and two nephews in World War I, the book focuses on Edward Malone’s at first professional, and later personal interest in Spiritualism.
