From November and December of 1934.

The Sea Magician

King John's ghost was stalking The Wash, a vast marshy area in England, terrorizing and maiming the inhabitants. Then the mighty Man of Bronze investigated -- and discovered the impossible. The Wash was producing real gold ... from nowhere!

The Annihilist

The dread Annihilist was slaughtering the criminals of New York in wholesale lots. Hundreds of men were found mysteriously murdered, victims of the hideous pop-eyed death. The finger of suspicion pointed directly at one man, Doc Savage himself. Even as The Man of Bronze scrambled to solve the terrifying enigma, the invisible assassin began to play havoc with one of humanity's most important secret defenses -- Doc Savage's legendary crime college.
