The phrase that springs to mind when trying to describe The Lost World is 'of its time'. That is to say that it is sexist, racist and hunting endangered animals is considered heroic. If (gritting your teeth and groaning in horror) you can get past all that and try to enjoy the story, the plot itself is also 'of its time'. Here we have four adventurers who discover an isolated plateau in South America where prehistoric life is abundant. With creatures from completely different eras sharing a home, while the isolation goes some way to explain how they have escaped extinction, it's never clearly explained why they have also escaped evolution, particularly in the case of the ape-men who are supposedly the ancestors of humans. Anyway, the dinosaurs are almost unrecognisable to the post-Jurassic Park audience. These are not the fast, intelligent hunters who can open doors and use decoys to lure their prey, creatures deserving of both our nightmares and respect, no these are the clumsy dumb dinosaurs of the Victorian attitude, creatures too stupid to avoid their own extinction, who while chasing you down will forget you ever existed should you happen to fall down a hole directly in front of them. There's no awe for these creatures, they are ugly and horrible and deserve to be shot and hung on a wall. And that's because, again bafflingly for the modern audience, the dinosaurs aren't the stars of this story, they are mere set-dressing. This story is about ape-men. The concept of the missing link was what would have hooked the Edwardian audience, with ideas of evolution still being relatively new and exciting and a contentious hot-topic for their parents, the lover of the adventure story would have grown up imagining this sort of exciting discovery and find the brutish terror of a club-wielding ancestor to be the height of entertainment, whereas today with evolution mostly taken without a thought, ape-men are dull and giant monsters who can open doors is what we want. Of course, on discovering this race of ape-men, our heroes immediately murder them all, because that's totally morally justified and not a horrendous thing to do.
The other problem facing The Lost World, and a more pressing one because it hasn't its age to excuse it, is that the characters are neither interesting nor likeable. Our narrator is Malone, who in typical Doyle narrator style, has almost no personality at all. He is a vapid vessel here to describe the exploits of the much more interesting men around him. All we know about him is that he is Irish, a journalist, fairly fit, stupidly stubborn and has some creepy opinions about women. Otherwise he's just a blank blob that tells us what is going on. The only reason to have this story narrated is to notch up the peril-level, because if he dies then we don't get the rest of the story, and it makes the threat a little more immediate. Then there's Lord John, who other than being a ridiculous caricature with his 'what ho'ing, only exists to shoot things or passionately want to shoot things. He just loves killing. Considering the story is set in a place with all of the rarest living things in the world, in any other story this character would be a raging villain. But even bland Malone catches his bloodlust. Then we have the professors. Summerlee, the least defined character, is described as being sarcastic and that's all we get. We are only really told about him, rarely seeing him as an actual person, and he only exists for the joke that he and Challenger argue like children all the time. Which brings me to our main guy, Professor Challenger. His whole characterisation is played for laughs, he's a ridiculous over the top madman, but it doesn't change the fact that he's utterly repulsive. He's so arrogant, condescending, rude and unfeeling about other people all of the time that no real person could bear to be anywhere near him. Even the characters in the book only put up with him because he is for the most part right, although we are encouraged to laugh whenever he messes up. What we are left with is characters we are supposed to mock, or characters who are too bland to care about, or characters who are so murderous that you kinda hate them. If they all got eaten by dinosaurs I might actually have enjoyed the story more. But dinosaurs are too stupid and ugly to do anything that interesting.
A further note about this edition. It's a collection of four Conan Doyle stories. When I bought it many years ago, I mistakenly thought it was a collection of all the Professor Challenger stories. Instead it contains the first two Challenger stories (The Lost World and The Poison Belt - which is EVEN MORE RACIST) and then two random short stories about monsters (The Terror Of Blue John Gap and The Horror Of The Heights). Whose idea was this random mishmash? It doesn't make sense. Since the first two stories are Challenger stories, it's annoying that the rest are unconnected. You wouldn't start a collection with two Sherlock Holmes stories and then change randomly to other stories (it should either be all or none, surely). The two short stories at the end are about monsters, so there is a thematic connection to The Lost World, but The Poison Belt isn't about monsters so then why is it here? It's just random to shove these four together like this. Also the cover of the book is from the long-forgotten BBC adaptation which, not only bore very little resemblance to the plot of The Lost World (although can you blame them) also includes two entirely made up characters - on the other hand I see that Challenger was played by Bob Hoskins and it's nice to see him again. I will say that the introduction to the book by Philip Gooden is actually very interesting (I usually hate introductions but if anything I think I enjoyed his essay more than the novel) and he's also added some end notes that readers may find educational.
