SUMMARY.
“The Underground City” follows mining engineer James Starr (protagonist) as he receives a letter from an old friend and coworker, Simon Ford (foil character), requesting that he revisit the depleted Aderfoyle coal mine in Scotland that he used to manage.
Upon arriving, Starr finds the entire Ford family living in the mine; and Ford explains that a new coal vein has been located.
Soon after Starr’s return, however, strange events start to occur, which seem to be supernatural (goblins & firemaidens). After a startling discovery, the characters continue to investigate these supernatural occurrences over the course of ten (10) years.
Accompanying Simon Ford are his wife Madge, and adult son Harry. In the cavern system Harry Ford finds an orphan girl named Nell while he was exploring. Eventually, Harry and Nell announce their marriage.
At story end, it become clear that that supernatural happening have been caused by Silfax (former mine employee) who has inhabited the mine since its closures.
