Letter From John William James

Warning This Section Does Contain Spoilers

He boasts that Bob, Robert Heck, is his singular possession, that he belongs solely to JWJ and that he exists only for JWJ, which certainly may be true. He then has the word possession in the middle of the page for no apparent reason. To see why please visit here
