I just can't figure out the decipher ting in chapter 10, don't see any pattern at all. If it's suppose to be like a Caesar replacement code, with J=S and P=E, that doesn't make much sense to me, since there is 9 between J and S, and 15 between P and E. All hints exhausted, still didn't get it. Any help?
