[Doc Savage (Bantam) #97, 98] • Cargo Unknown

Satan Black

The Man of Bronze is pegged for murder in a family feud over a pipeline stretching from Arkansas to the Atlantic. The precious oil it carries is needed by the army for the invasion of Europe that will end the war. Only Doc Savage and his fearless sidekicks can find the real culprit and see that the pipeline gets built — at the risk of death by dynamite!

Cargo Unknown

Doc Savage’s men are on a top secret mission aboard the Pilotfish when the submarine explodes and sinks to the ocean floor. The Man of Bronze tracks down the treacherous vipers behind the sabotage and searches for the purgatory of terror 200 feet below the ocean surface — with only 12 hours of air left!
