 What was the only thing that mattered to Charles near the end?
There should be an epitaph for every man, big or little, but a really grand and special one for Loner Charlie. New York lay quietly below him. It was the hour of indecision when day has not quite made up its mind to leave and night has not yet attacked in force. A month later the meat animals, the birds and the household pets began dropping as rapidly as the flies which had dropped earlier. Within a year it was obvious to everyone that man was the only animal left on earth. And now.... "I've got to find out," Charles told himself. And again at the age of 10 each child returned to the Bureau for a recheck. Charles was by himself, the last person alive in all of New York City.
