Penguin edition of Arthur Conan Doyle's "The Lost World and Other Thrilling Tales" comes with four tales: "The Lost World," "The Poison Belt," "The Terror of Blue John Gap" and "The Horror of Heights."
The first two stories (both are long ones) features Doyle's famous creation besides Holmes -- hot-tempered genius Professor Challenger. "The Lost World" is narrated by a newsreporter Edward Malone, who seeks for the chance to show before his love Gladys that he also could show the heroism by doing a great thing. So he grabs the opportunity to accampany the exploration team to prove the theory of Professor Challenger that there is a plateau untouched by the modern civilization deep in the South America where extinct animals are still living.
So, there go four characters -- Challenger, Edward Malone, Lord John Roxton (a nice-guy type of sportsman), and Professor Summerlee, who wants to disprove Challenger's theory by his own hand. The adventures themselves including the encounter with dinosaurs or other creatures are written with vivid touch, even though some parts are clearly dated. And some readers may feel uncomfortable when reading some violent scenes.
This story is filmed many times -- most as early as in 1925 -- but the ending is much different. Interestingly, the dinosaurs are not the main feature of the novel (even though Penguin's cover suggests the terrible havoc they do on the city, which is unashamedly borrowed in Steven Spielberg's film of the same title).
"The Lost World" (1912) was written immediately before WWI, and perhaps was the last romance that could depict the heroism in this way, in a remote country, against the exotic background of the Amazon. If you like it, read "King Solomon's Mines" or "She" by H. Rider Haggard, which were written in the late 19th century.
"The Poison Belt" the second "Professor Challenger" tale sounds more apocalyptic, beginning with the newspaper column of the Professor who predicts the mass destruction of the human beings. The story brings back the four characters of the last adventure, and shows how the world ends as Malone et al. see it. Though the story lacks scientific precision (what's "ether"?, you may say) and the final chapter is a huge letdown, the story is full of impact, describing the fear and terror of the people facing death. Some parts of it still look very modern and immediate, as if the scenes from "Dawn of the Dead" or "28 Days Later."
The last two shorts are comparatively weak, but not bad. "The Terror of Blue John Gap" is, as the title suggests, about the terror of the underground while "The Horror of the Heights" could be rephrased as "the horror seen by a daredevil pilot."
The Penguin edition has Philip Gooden's insightful introduction which also tells us the real-life models of the characters. He also provides useful notes, and the book has the original illustrations (the kind of garish drawings capturing the shocking moments of the story), which are pure delight to see. A good read for holidays.
