E.C. Tubb 
Pandora’s Box [EPUB ebook] 

Written under the working title of "The Spore Menace" in 1954, Pandora’s Box was not actually published until 1996. Many of the ideas in this novel are seminal, even prophetic. Tubb was one of the very first sf writers to realize the potential danger to Earth from alien organisms. He appreciated that whilst technology may change, Man’s nature remains the same and Pandora’s Box spins a fascinating tale based on that most basic human emotion – greed!
