She wrote it without spaces: — no. Then he said, “What if the cipher isn’t just A→B but A→Z? Try shifting each letter back one in a circle: Z becomes Y, A becomes Z. Now try.”
p (16th letter) → o (15th) s (19th) → r (18th) v (22nd) → u (21st) c (3rd) → b (2nd) l (12th) → k (11th) f (6th) → e (5th) v (22nd) → u (21st) b (2nd) → a (1st) p svcl fvb
Then she realized: she had to treat the phrase as one string, but the letters she wrote — — if she shifted each of those back one again, she’d get nonsense. She was stuck. She wrote it without spaces: — no
p → o space s → r v → u c → b l → k space f → e v → u b → a Now try
“I love you,” she said.
