The Marks — Volume I of Off the List

He already knows he can get in. What he's deciding is whether anybody will notice.

Twenty-five years on patrol taught me that almost none of it was random. A house gets chosen days before it gets entered, from the sidewalk, in under a minute — and the way that decision gets made is by leaving something small behind and coming back to see whether it moved. A leaflet wedged low in a door seam. A pebble on a step. A plastic tie on a gate latch.

73 numbered checks across nine modules. What gets left on a house that is being tested, what each thing is actually testing, and the sixty-second walk that finds it the same day it was placed.

One module is about nothing but telling a real mark from a coincidence — what wind does, what animals do, what your mail carrier does, what children do. One pebble is a pebble. A book that teaches you to see threats everywhere has made you worse off, not safer, and this one says so.

Every check is free to do. There are no prices in this book and nothing to buy.

Includes what to do when you find one, in order, and the exact words for the non-emergency call.
