Synopsis for Superman: "... and the Numbers Racket"
Superman rescues a man from committing suicide, and the guy turns out to be a thief, whose straight life has been completely ruined by gambling. This motivates crusading journalist Clark Kent, the next day, to visit the Police Commissioner and urge him to act forcefully against the numbers racketeers and other gambling gangs that are preying on the city. But the commissioner just blows him off.
Superman then goes to work, demolishing one illicit casino after another, hospitalizing many low-level thugs, and directly threatening death to several gang bosses. One boss calls in some help from his ally, the Police Commissioner, and Superman convincingly threatens both of them, with death. They flee the city.
Superman then convenes a meeting of all the gambling racketeers, and compels each of them to draw a card. He announces that he will kill the holder of the ace of spades card, unless he immediately leaves Metropolis, never to return. Superman has, of course, dealt every single one of them an ace of spades, and they all leave town very quickly.

Synopsis for Pep Morgan: "Bodyguard"
Because he had helped to save his warehouse business, Mr. Smith trusted Pep Morgan with another job, one that was much more personal to him. He had received several letters threatening harm to his daughter, Mary, unless he came up with 200,000 dollars to pay in protection. He wanted Pep to guard her, but without alerting her to any danger. Smith didn't want her to worry, after all. So Morgan spent the next week as a guest at the Smith home, showing Mary how to swan dive, after which they shared a meal together. A few nights later, the house servant opened the door for a bunch of crooks, leading them to Mary's room. They kidnapped the poor young lady, dragging her back to their car. Pep woke up and gave chase to their vehicle, following it all the way to the city cemetery. The thugs grabbed Mary and pulled her out of the car. Pep was on top of them almost immediately! He stole one of the thugs' guns and held up the others until the police arrived. The next day, Pep and Mary celebrated aboard one of Mr. Smith's boats

Bandits appear and start pelting him with stones and arrows. His horse is killed, forcing Marco to climb up a nearby ravine in a desperate attempt to escape! Climbing up to a narrow pass, Marco follows it. Unfortunately, it stops at a dead end, and with the slavers and bandits at his back, it looked like he was done for! Suddenly, the men start falling left and right, hit by large rocks being thrown from above by Marco's mysterious rescuers.

The excited duo are then greeted by a swarm of angry bandits with sharp swords. From the entryway comes a man dressed in regal clothing. Calling him their master, the Pharaoh Cheops, the Arabs all bow down before him.

- Published by Detective Comics, Inc.
- Superman and the Numbers Racket is reprinted in Superman: The Action Comics Archives Vol. 1 and Superman Chronicles Vol. 2.
- First named appearance of the city of Metropolis.
- Convergence #0 states the first appearance of "Pre-Crisis Earth-Two Metropolis" was in The Flash #123 (rather than in Action Comics #16). This supports E. Nelson Bridwell's suggestion, in the Superman Family letters page, that the characters and places of Earth-Two, and those of the actual Golden Age characters and places, were two different things. Many (but not all) of these stories were assigned to "Alternate Earth-Two" (Earth-Two-A).
- At the end of the 1930s and the beginning of the "golden age" of superheroes, as shown in several early Superman stories and at least one Green Lantern story, the municipal and state governments of Metropolis were riddled with corruption.
- Superman appeared last in Action Comics #15. He appears next in Superman #2.
- George Taylor appeared last in Action Comics #15. He appears next in Superman #2.
- Again the main cover art is something other than Superman. Of the sixteen issues of Action Comics published so far, Superman has monopolized only five covers.
- Gargantua T. Potts mentions buying Action Comics in the Tex Thomson story.
- Zatara mentions Action Comics in his own story.
