 A much later Lost World novel is Michael Crichton's "Congo", which is set in the 1970s and features characters seeking a trove of diamonds in the lost city of Zinj for use in electronic components rather than jewellery.As in "Treasure Island", the narrator of "King Solomon's Mines" tells his tale in the first person in an easy conversational style.Almost entirely missing (except in the speech of the Kukuanas) is the ornate language usually associated with novels of this era.
