At the celebration of his hundredth birthday, local billionaire Francis Hearty Withers announces to the people gathered on the front lawn of Witherston Baptist Church that he has finalized his will. In it he bequeaths $1 billion to his north Georgia hometown of Witherston and another $1 billion to be divided up equally among the town's 4,000 residents—in recognition of their support of a Senextra pharmaceutical factory.

Senextra is a drug that enables individuals to lead healthy lives well into their second century, but it has some unanticipated consequences. The group assembled to hear Withers's announcement do not all applaud. One person carries a sign that says SENEXTRA VIOLATES MOTHER NATURE. Another, KEEP SENEXTRA OUT OF OUR SYSTEM. A third, WE DON'T NEED MORE OLD MEN.

Withers vows to change his will and disinherit the community. Two days later he is found dead. Who killed him? And why?
