When They Come From Space

Mark Clifton (1906–1963) was an American science fiction writer. About half of his work falls into two series: the "Bossy" series, about a computer with artificial intelligence, was written either alone or in collaboration with Alex Apostolides or Frank Riley; and the "Ralph Kennedy" series, which is more comical, and was written mostly solo, including the novel "When They Come From Space", although there was one collaboration with Apostolides.
