She looked at her watch. It was just past eleven. “Harry, get in here,” she called. As she turned back toward the front door, she heard the sound of -a car going by out on Beach Mill Road.

She was surprised to see that they were watching Train von Rensel, who stood like a stubby oak tree, alone in a space about fifteen feet square.
