The Maracot Deep
Arthur Conan Doyle
 The novel revolves around the legend of Atlantis, mentioned as an ancient city or continent which was drowned by the sea due to divine intervention. The novel is narrated by Headley who first writes a letter to his friend Sir John Talbot. On his subsequent rescue, he completes his story giving details on his escape and how they fought off possibly the greatest danger to humanity, the Devil himself. The novel begins with preparations for the dive, off the coast of Africa. Prof. Maracot claims to have located the deepest trench in the Atlantic and is vehement that he shall go down in the specially prepared submersible actually a bathysphere along with Headley and Scanlan. On reaching the edge of the trench, a description of the undersea world is presented. The team comes face to face with a giant crustacean who cuts off their line and hurls them down into the trench. Down in the trench, the team is rescued by the Atlanteans who are the last survivors of the land that was Atlantis. Although the description of Atlantis may not sound quite futuristic and may seem fantastic, the fact that the novel was written in 1929 should be taken into account. One device in particular is often made use of. This is a thought projector which visualizes the thoughts of a person for others to see. This helps the team and the Atlanteans to communicate. Descriptions of work habits, culture and various sea creatures are provided. The Atlanteans forage for their food from the sea bed and their slaves, Greeks who are the descendants of the original slaves of the kingdom of Atlantis work in undersea mines. This is made possible thanks to an exceptionally strong and light transparent material which is fashioned into helmets to enable people to work underwater. The team eventually uses the levity of these spheres to escape to the surface. Headley elopes with the daughter of Manda, leader of the Atlanteans. In the later part of the novel, Headley describes the encounter with the Lord of the Dark Face, a supernatural being who led the Atlanteans to their doom and was the cause of untold miseries to humanity ever since. This being is likened to the Phoenician god Baal who was demonized by later religions and cultures. The being is defeated by Prof. Maracot who becomes possessed by the spirit of Warda, the man who managed to convince a handful of Atlanteans to prepare for the worst and thus built an Ark which saved them from the cataclysm which destroyed their land.
