The Land of Mist, by Sir Arthur Conan Doyle

The Land of Mist is a novel written by Arthur Conan Doyle in 1926. Although this is a Professor Challenger story, it centres more on his daughter Enid and her colleague. Heavily influenced by Doyles growing belief in Spiritualism after the death of his son, brother, and two nephews in World War I, the book focuses on Edward Malones at first professional, and later personal interest in Spiritualism. There is a suggestion in chapter two that the deaths of "ten million young men" in World War I was by punishment by the Central Intelligence for humanitys laughing at the alleged evidence for life after death.
