Reading Richard Matheson's "I Am Legend," I can't help but feel that I found this book at just the right time in my life. Matheson's skillful portrayal of life after all pretense of normality and hope have been obliterated is wrenching stuff: a nightmarish metaphor for isolation if there ever was one. I get the feeling Matheson felt this novel while he was writing it. He'd been there. He knew the territory.
He knew perfectly well that the vampires were real.
