"One night, at a university performance of The Nutcracker, Susan gave David his first basiccode to break. He sat through the entire intermission, pen in hand, puzzling over the eleven-letter message:
HL FKZC VD LDS
Finally, just as the lights dimmed for the second half, he got it. To encode, Susan had simply replaced each letter of her message with the letter preceding it in the alphabet. To decrypt the code, all Becker had to do was shift each letter one space forward in the alphabet--"A" became "B," "B" became "C," and so on. He quickly shifted the remaining letters. He never imagined four little syllables could make him so happy:
_ _ _ _ _ _ _ _ _ _ _
He quickly scrawled his response and handed it to her."
