He left me something else.
Just a number, scrawled on the wall, with a message underneath.
Solve it within a week, or never see him again.
Skip, skip, skip.
He's saying James is still alive. But I can't do anything about it. Trying an A-D substitution cipher doesn't work, even though that would be a 3 letter switch. Same with an A-X, which would be -3. If I don't figure this out, James is gone. Forever.
