《Land of Mist》 - 免费有声读物

The Land of Mist is a novel by British writer Arthur Conan Doyle, published in 1926. Although this is a Professor Challenger story, it centres more on his daughter Enid and his old friend Edward Malone. Another friend from the 1912 novel The Lost World, Lord John Roxton, is also involved in the novel's second half. Professor Summerlee, who has died of old age around this time, is referred to by the mediums (much to the anger of Professor Challenger). - Summary by Wikipedia
