Her eye caught the middle: "lktkwth" — that looked like "l k t k w t h" — seven letters. "l k t k w t h" could be "l a t a w t h" if you shifted... No. But "k" to "a" is minus ten. Inconsistent. nwdz msrb lktkwth sghnnh bjsm abyd wks...

Lena grabbed her coat. "Rami, we walk into a trap tonight. But if we don't go, we never know who's been rewriting history from the shadows."
