We had the shop keeper of the Bookstore in Jacksonville help us
This is the clue that was in the Civil War - North vs South book
What stands out so far:
- The capital letters Spell "LOOK DEEPER"
- The signature is an anagram that spells "LOOK DEEPER"
- The impression text at the very bottom looks like the name
"Rusty Shackleford"
There also seems to be an impression line drawn from the word "this" -
in the phrase "end of this trail of clues I laid" - possibly highlighting further significance for the name "Rusty Shackleford"
We have been unable to figure out what the impressions below and to the right of Rusty Shackleford are.
A theory:
We know that our end game is to find a Email address and a password. The title "THE LOCK" might signify the email address. The password would be the key. This letter could be pointing us towards the email address.
OPs hints:
215 North Laura Street The Civil War North vs South
SOLUTION OF PUZZLE: you have to count all the intersections on the line drawings and then find correspondong letter in LOCK message from Bookstore
