- Gregory Stark gets a letter at the office. Comes FedEx. Stamped "Personal and Confidential". Sender's name marked as "Past Due Collections". Laser-printed, not very long. Starts out: "Mr. Stark, I have evidence linking you to your crime. You may entertain notions of impunity. But in the end everyone is culpable." There's a succession of $100,000 payments to be collected. He gets letters which lay out a maze and at the end of the maze he makes the drop.
