When I was sixteen my high school math teacher dissapeared. It is now several years later and I am at my high school reunion. just a week before I received a letter which was in code, when I got to my old high school I realize I'm not the only one who got the letter, everyone else did as well. When I look at the code it looks like the puzzles my teacher gave my class on some days! This is a big discovery, my math teacher may be found. If only we could decode the message. I guess now we have to do this on our own because according to the police, FBI, and CSI she will probably never be found. But I won't give up, not when I am so close, I will keep searching.
