as far as i can remember, and its along time since i read them, a group of aliens on mars, did not want to be infiltrated, and absorbed the people who came into their lives by pretending to be like them!. pretty creepy really!. they sort of looked into their minds and recreated their lives, the families they had left behind!. etc!. they were a dying race!. ray bradbury wrote them,Www@QuestionHome@Com
