"Pen number" and "Fibbie" etc. reading John Grisham's "Firm",chapter 36, "That's a Code Three account, opened by a T. Hemphill, with access only by her and a certain male meeting the following physical requirements: approximately six feet tall, one seventy-five to one eighty-five, blue eyes, brown hair, about twenty-five or twenty-six years old. You fit that description, sir" "Sir, what is your Pen number?" what puzzles me are: 1. What is a "Code Three account", 2. "one seventy-five to one eighty-five" refers to what? 3. What is a "Pen number", password? why "Pen" is always capitalized here? 4.the book uses "Fibbie" to refer to FBI agent, why, it can not be found in any dictionary available to me. thank you for your help,
