Professor Challenger Series

* The Lost World *
Edward Malone, a young reporter for the Daily Gazette, asks his editor for a dangerous assignment to impress the woman he loves, Gladys, who wishes for a great man capable of brave deeds and actions. His task is to approach the notorious Professor Challenger, who dislikes the popular press intensely and physically assaults intrusive journalists. The subject is to be his recent South American expedition which, surrounded by controversy, guarantees a hostile reaction.

* The Poison Belt *
Challenger sends telegrams asking his three companions from The Lost World— Edward Malone, Lord John Roxton, and Professor Summerlee— to join him at his home outside London, and instructs each of them to 'bring oxygen'. During their journey there, they see people's behaviour become excitable and erratic. 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, based on its effect on the people of Sumatra earlier in the day, he expects to stifle humanity.

* The Land of Mist *
Focused on Challenger's daughter Enid, the story describes Edward Malone's at first professional, and later personal interest in Spiritualism.

* When the World Screamed *
Professor Challenger, with the help of Edward Malone and Peerless Jones, drills into the Earth until he reaches the mantle, convinced that it is a sentient being and that by doing so he will be the first person to alert the planet about mankind's presence.

* The Disintegration Machine *
Professor Challenger is arguing with people who are persistently calling him on the telephone when his young friend Malone, a reporter for The Daily Gazette, enters and requests Challenger accompany him to inspect the discovery of Theodore Nemor, who claims to have invented a machine capable of disintegrating objects. Skeptical of the invention, Challenger accepts Malone's proposal and accompanies him to the house of Nemor.
