Psst! Over here!
My name is Agent C and we have a very important mission for you.
It has come to our attention that a secret organization is operating covertly in the Chattanooga area. We know that their hideout is somewhere within the city, but we're not sure where.
Recently, Agents N and M came across a file with cryptic messages written inside (PDF). It is your job, new recruit, to decipher the meaning of these messages and to photograph them. It is of the utmost importance that we obtain an accurate photograph of as many of the locations and objects and possible.
You are our last hope. Do not fail us or our entire operation will be lost!
