"I have been asked what I mean by 'word of honor.' I will tell you. Place me behind prison walls--walls of stone ever so high, ever so thick, reaching ever so far into the ground--there is a possibility that in some way or another I may escape; but stand me on the floor and draw a chalk line around me and have me give my word of honor never to cross it. Can I get out of the circle? No. Never! I'd die first!"
