question:  What did Charles decide to do when he realized he was alone?
context: There should be an epitaph for every man, big or little, but a really grand and special one for Loner Charlie. He touched buttons by the edge of the bed and the illumination quieted to a soft glow, wrapping her in a radiant halo. 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. Trembling, he dropped to his knees, his head against the cold firmness of the sill, his hands clutched tightly around the jagged edges of the window pane. Charles picked it up and folded it across her now cold breasts. 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. The panic which had begun with the death of the animals was quieted somewhat by the fact that humans seemed immune to the pandemic. But the lakes full of dead fish caused a great stink and residents along the coasts began to move inland. Less than a month ago no more than a few thousand people remained in New York. And now.... "I've got to find out," Charles told himself. Once a year the Bureau issued The Index, an exact accounting of Earth's four billion inhabitants. In all of his life, Charles had never once glanced at The Index. Reaching the gigantic building, Charles pushed aside the body of a young man and walked into the main foyer. Only once, before the plague, had he seen the interior of this room. And again at the age of 10 each child returned to the Bureau for a recheck. It was for this latter recording that Charles had come to the Bureau some twenty-two years before and a friendly guard had let him peep briefly into the computer room. The impression of intense activity, of organized confusion, of mechanical wonder had remained with him the rest of his life.
