Bill Wile is an easygoing, hardworking guy who leads a quiet, ordinary life. One evening, after his usual eight-hour bartending shift, he finds a typewritten note under the windshield wiper of his car. If you don't take this note to the police and get them involved, I will kill a lovely blond schoolteacher. If you do take this note to the police, I will instead kill an elderly woman active in charity work. You have four hours to decide. The choice is yours. It seems like a sick joke, and Bill's friend on the police force, Lanny Olson, thinks so too. His advice to Bill is to go home and forget about it. Besides, what could they do even if they took the note seriously? No crime has actually been committed. But less than twenty-four hours later, a young blond schoolteacher is found murdered, and it's Bill's fault: he didn't convince the police to get involved. Now he's got another note, another deadline, another ultimatum--and two new lives hanging in the balance
