The pulp era's greatest superman battles evil in two of his earliest exploits by Lester Dent (writing as Kenneth Robeson). After stowing away aboard a ghost zeppelin, Doc and his Iron Crew tangle with a bizarre vampiric murderer and villainous Arabs who are protecting the secret of 'The Lost Oasis.' Then, while returning to New York via ocean liner, the Man of Bronze encounters modern-day Amazons in Lester Dent's all-time favorite Doc Savage story, 'The Sargasso Ogre.' This classic pulp reprint also features the original 1933 pulp covers by Walter Baumhofer from the ultra-rare (and expensive!) seventh and eighth issues of Doc Savage Magazine, the unsold 1936 Doc Savage newspaper strip by Lester Dent and Paul Orban, and historical commentary by pulp historian Will Murray, author of seven Bantam Doc Savage novels!
