Once the door stood ajar, I pulled the door behind me closed, shutting myself off from the world; a Hardy Boys move if there ever was one. Turning around and positioning my body sideways, facing the interior wall of the house, I slipped two fingers into a three-inch, steel diameter ring that looked like it belonged on a bull’s snout, and locked the door and faux bookcase behind me, keeping all trespassers at bay. Then I moved into the private room ahead of me, on business.
