Mystery of the Atomic Boomerang

William Nasland and Fred Davis Jr. are among soldiers dispatched to a recently captured Japanese island in order to clear it out of any remaining hostiles. As they search the area a strange explosion with no apparent source goes off. As more explosions go off in supposedly cleared zones, William and Fred slip away to change into Captain America and Bucky to investigate further.

Not far away, Japanese soldiers led by Professor Sico Rudo gloat over their victory over the soldiers with their new weapon Atom Water. Found by Captain America and Bucky, a fight breaks out but the Japanese soldiers escape when Rudo unleashes an Atom Water explosion that stuns Cap and Bucky. Searching for clues as to how these explosions occur, Bucky finds and pockets a magnifying glass dropped by a soldier. Hearing another explosion, Cap and Bucky follow it's trial back to a cave where Rudo and his men are hiding out with their supply of Atom Water. Cap and Bucky are soon overpowered and knocked out and Sico decides to use the Atom Water to kill the two heroes.

Tying up the two heroes, Rudo places them in a nice sunny spot and surrounds them with Atom Water, explaining that it explodes once it starts to evaporate and then mockingly leaves a sample vial of the water before leaving the two heroes to die. With their lives in peril, Cap remembers Bucky's magnifying glass and uses it to burn through their ropes and get free. Cap then picks up the vial of Atom Water and tosses it into the cave opening while they flee the explosion.

Hearing the blast Rudo and his men assume Cap and Bucky are killed but are soon ambushed by the two heroes. With the battle fairing poorly, Rudo shoots his men and attempts to flee. Cap and Bucky chase him back to his cave where Rudo mistakes Cap and Bucky's hesitance to follow him is cowardice. However, Rudo realizes his fatal mistake when the broken vial of Atom Water explodes, killing him and destroying the rest of of the supply.

Recovering a vial of Atom Water from one of the dead soldiers, Cap turns it over to the military brass who tell the two heroes that the United States has developed a more powerful weapon: The Atom Bomb.

Killer from the Grave

Rufus King is walking the streets when he is suddenly confronted by his nephew Danny who shoots him dead. When the authorities arrive, they fail to stop Danny from escaping, and fail to recognize him, but manage to note the license plate number on his getaway car.

When Rufus King's death is reported in the newspaper, the Human Torch and Toro recall that Rufus had his nephew Danny committed to an insane asylum despite Danny's pleas that his uncle was attempting to force him out of the family fortune. Suspecting that Danny is the likely suspect, the two heroes pay a visit to the police to compare notes. Learning that the police are looking into the license plate, the Torch calls the state insane asylum and learn that Danny King apparently died months earlier, and they find that stolen car abandoned in a ditch. Going there, the Torch and Toro learn that the police were able to lift a print from the steering wheel. Comparing the prints to those of criminals turns up no match, but when the Torch suggests comparing it to the prints of mental patients, they find it matches Danny King's prints exactly.

Suspecting that Danny faked his death, the Torch and Toro race to the asylum where they question Dr. Hack, the man who signed Danny's death certificate. Pressing Hack for information, the Torch learns that he helped fake Danny's death and that Danny is hiding out at the State Hotel. The Torch and Toro then race to the hotel where they apprehend Danny and turn him over to the police. At the police station the Torch tells Toro he suspected Dr. Hack since doctors don't typically write death certificates AND dispose of the bodies.

Fraternity of Fat Fellows

William Nasland and Fred Davis Jr. are walking down Metropolitan Avenue when they hear an argument. They then find portly Jonathan Mortimer being pushed out of a building by the superintendent. Helping the man up and joining him for lunch they learn of his strange predicament: A mortician, Mortimer was advised by his assistance Beese that there was a "Fraternity of Fat Fellows", a foundation that benefits over weight men, and that was seeking new members. Mortimer joined the fellowship and part of his job was to work at their office at 77 Dunhill Lane every day until noon. Then that day he received a letter informing him that the Fraternity had dissolved and went to investigate, thus leading to his altercation with the landlord.

Leaving Jonathan's company, William believes that someone is playing an elaborate prank on the man and decides they should investigate as Captain America and Bucky. The two heroes arrive at Mortimer's mortuary where they are spotted by someone inside. Suddenly a van leaves the facility and the back end opens up and a gunman begins firing on them. Diving into the back of the truck, Cap and Bucky fight their attackers and learn that they are employed by a criminal calling himself the Chameleon. As the driver bails out of the truck, Cap and Bucky jump out as the truck drives off a bridge.

Suspecting the crooks plots, Captain America begins tapping the ground out front of the mortuary, but finds it sold. While inside, believing Captain America to be dead, the Chameleon meets with his men to begin planning the next part of their plan when suddenly the alarm is tripped. The Chameleon orders his men to hide in coffins as Cap and Bucky enter the building. Finding nothing out of the ordinary, Cap and Bucky are found by Mortimer. They ask him introduce them to his assistant, who they learn is apparently ill and confined to his bed. However, Cap notices something and leaves. Outside, Cap begins tapping the ground outside finding a hollow noise coming from below. Heading back to the mortuary, Cap asks Mortimer if Breese was in charge while Mortimer was at the Fraternity each day. Confirming this, they rush back down into the basement of the mortuary and find the Chameleon and his men attempting to rob the bank next door through a secret tunnel they built connecting to the mortuary.

The two heroes are overpowered and then tied up onto a conveyor belt leading to a massive furnace and are left to die. Cap spots a loose live wire and manages to grab it in his teeth and use it to short out the conveyor. Breaking free of their bonds the two heroes then easily round up the gang, unmasking the Chameleon, revealing him to be Beese.
