The Stanley Parable (Book edition)

What could it mean, Stanley wondered aloud to nobody. He began wildly tearing through papers on the boss's desk, pulling books off the shelf, looking behind paintings, desperate for clues to his situation. But his attention was caught by a keypad behind the boss's desk. What could its purpose be? In fact, this keypad guarded the terrible secret that lay buried below his feet. And so the boss had assigned it an extra secret PIN #. 2845. But of course, Stanley couldn't possibly have known this.
