The 'Land of Mist' is the third novel in Arthur Conan Doyle's 'Professor Challenger' series. The first was written in 1912 and is entitled 'The Lost World', describing an expedition to a plateau in South America where dinosaurs still survive. Then in 1913 he wrote 'The Poison Belt', describing a disaster as the earth passes through a cloud of poisonous ether. Finally, in 1926 'The Land of Mist', which is heavily influenced by Doyle's growing belief in Spiritualism after a number of his close relatives died. It is therefore seem as semi-autobiographical, Challenger and Conan Doyle both grieving men and both interested in Spirituality.
