Chance. That was it! The laws of probability, the bell-shaped curve, normal distribution, rectilinear regression. More people per square foot in New York than elsewhere. The first person who died was from New York, so the last person who gave way to the disease should come from here too. Spin the wheel; throw the dice; toss the coin.
So simple to explain by the laws of chance. No need for any underlying assumptions about good and evil, no need for teleological arguments concerning cause and effect. Simply explain it by chance. Somebody had to be the last to go and that was—
"No," Charles said, standing up in the quiet of the spring evening. "No, chance won't do it. No man can reckon with chance. The mind rejects such things. There must be something beyond mere accident. There must be!"
He sighed slowly.
"So now I'm a hermit, whether or not I like it," he said in derision to the gravel path as he walked along it. "A hermit in the midst of a city of millions of—No, I forgot. There aren't any more people, are there?" It was hard to realize, even now. "A hermit, alone—and I haven't even got a cave...."
Charles stopped walking suddenly. No cave, he thought. No place to sleep out the long one, no place to rest while time came to change things around and make them for the better. No place to hide.
And suddenly it was the most important thing in life to him to find his "cave."
It took him almost an hour to find the proper tools, and better than two hours more of hard, nighttime work to get the hole dug to his satisfaction. It took almost three hours to find the right sort of casket, durable but not too heavy for one man to handle. He carted it out to a grassy plot close to the center of the park where the grave was. He let the coffin down slowly into the depression, then piled up loose dirt on the sloping sides of the hole so that the rain would wash it down over him.
"I can't very well bury myself," he said. "I guess it will rain after I'm gone." He looked carefully down at the metallic container.
