Evidence: Skylark Three Edward E. Smith, Ph.D. Skylark Science fiction Skylark Three (1948) is the second book in the Skylark series and is set a year after the events of The Skylark of Space, during which year antagonist Marc "Blackie" DuQuesne has used the wealth obtained in the previous book to buy a controlling interest in the story's 'World Steel Corporation', a large company known for its ruthless attitude. When the story begins DuQuesne announces a long absence from Earth, to find another species more knowledgeable than the Osnomians allied with protagonist Richard Seaton. Having used the 'zone of force' at first to conceal himself, and then to destroy the Fenachrone battleship, Seaton captures a leading crew-member, who reveals (upon interrogation) that the Fenachrone intend conquest of the entire Milky Way Galaxy, and eventually of the Universe, and that a message is already in progress toward the Fenachrone capital to summon aid. Meanwhile, DuQuesne and his aide have also interrogated a Fenachrone and plan to capture an entire Fenachrone battleship for personal use. Near the Green System, they are attacked by the hitherto-unseen natives of the planet 'Fenachrone', whose weaponry surpasses any known to Seaton or the Osnomians.
