Synopsis for "The Lost Land!"
Having a night alone with Betty Dean, the Sub-Mariner tells her a story about his ancestor who lived in Atlantis centuries ago before the continent sunk....
During those days Tolan felt an ill omen that would bring the end of his kingdom. One day, an inventor named Nagorbu developed a new magnet that could repel human flesh and offered it to Tolan as a new weapon they could use to gain superiority over the universe. Tolan believed that such a device was evil and ordered it dumped into the ocean where it sank to the bottom of the sea. However, Nagorbu had gathered faithful followers who attempted to retrieve the magnet and use it. However Nagorbu's constant searching and digging caused floods that eventually sank Atlantis and the survivors of that disaster developed the ability to breath under water and rebuilt their kingdom.
... Finishing his story, Namor is asked by Betty what happened to the magnet. Namor explained that the magnet eventually sunk to the centre of the Earth, eventually creating gravity. When Betty asks if the story is true, Namor tells her that he is uncertain how much is truth and how much is fiction.

Antagonists:
Synopsis for "The Drink of Death!"
The Sub-Mariner is tricked by the Spoiler into drinking a potion that the villain claims will cause Namor death if he comes into contact with water. The Spoiler then mocks the hero before going off and robbing the captain of the ship "Good Heart" which was carrying money for an orphans fund. When the captain returns to shore and asks Namor for help, the hero -- fearing the effects of the Spoiler's potion -- turns his back on him. The story is picked up by the press, disgracing the Sub-Mariner.
Aboard the Good Heart, the Sub-Mariner tries to explain his delicate situation when the Spoiler returns to steal the rest of the money. Namor fights the Spoiler who then flees in the water. Namor takes a gamble and dives in after him and finds out that he is unaffected and easily beats the Spoiler, who admits that the potion did not really work. The Spoiler is turned over to the authorities and Namor's reputation is redeemed.
Notes
- The story "The Man Who Grew" refers to Doctor Dill as Namor's "Arch Nemesis", this is referenced by the narrative, Dill himself, and the Sub-Mariner. However this is the only appearance of the Doctor Dill to date, how he managed to obtain such a distinctive title is unknown.
- The story "The Lost Land!" completely refutes the Great Cataclysm which is historically known as the cause for the sinking of Atlantis. The story recounted by Namor here is likely only an Atlantean myth.
- This is the first story in which Namor's home is actually referred to as Atlantis.
- Although the narrative of the Captain America story refers to him as Steve Rogers, as per the retcon of What If? #4 this appearance is attributed to Jeff Mace.
- Lem Snipe states that he was a Nazi spy who was captured by Captain America during the World War II. That said, as per the above mentioned retcon, this means that he was captured in 1940, during the period that Steve Rogers was active as Captain America. Which creates an inconsistency given the retcon, as Jeff Mace would not have captured Snipe. One could assume that his recognition comes from his access to government files during his tenure as Captain America in the late 40s.
