Three quintessential space operas by one of the founding fathers of modern SF. Arcot and Morey, a pair of young superscientists, foil a pirate who preys on giant airplanes carrying thousands of passengers in the year 2126. Then with the reformed pirate as their ally, they build a space ship that takes them to Venus where they end a war by whipping up a disintegration ray. Their ultimate, exploit involves an interstellar battle waged across the galaxies. The science is slipshod and the fiction is old-fashioned but action-minded adolescents and devotees of period pieces will be pleased with this volume.
