Underground City
Covering a time span of over ten years, this novel follows the fortunes of the mining community of Aberfoyle near Stirling, Scotland. Receiving a letter from an old colleague, mining engineer James Starr sets off for the old Aberfoyle mine, thought to have been mined out ten years earlier. Starr finds mine overman Simon Ford and his family living in a cottage deep inside the mine; he is astonished to find that Ford has made a discovery of the presence of a large vein of coal. From the outset, mysterious and unexplained happenings start to occur around the main characters, attributed initially to goblins and firemaidens.
