The complete adventures of the 'caveman in a lounge suit', the irascible, volcanic genius Professor Challenger and his stalwart regular band of fellow investigators into the frontiers of scientific improbability-Malone, the newspaperman, Lord Roxton, the soldier of fortune ever in pursuit of the next dangerous sensation and Professor Summerlee, Challenger's academic sparring partner. This volume, of course, includes the ever popular 'The Lost World', the predecessor to a varied collection of tales, in which man finds himself at odds with the ever hungry denizens of the prehistoric age. Enthusiasts will be overjoyed that Challenger and Co. gather together again for 'The Poison Belt' as mankind is doomed to almost certain extinction as a noxious miasma envelopes the planet. In 'The Land of Mists' our intrepid band take on the paranormal with excursions into the field of ghost hunting and the realms of spiritualism before Challenger and Malone must deal with an unscrupulous scientist who has succeeded in the invention of 'The Disintegration Machine' which he is prepared to sell to whichever government that is the highest bidder-irrespective of its appalling military potential. This collection concludes with 'When the World Screamed' in which the ever unconventional Challenger sets off on a perilous endeavour to prove that the earth itself is a living entity by giving it a painful shock! These are some of Conan-Doyle's best loved characters brought together in one roller coaster volume for your enjoyment.
