Lou Williams stood in front of the huge window that dominated most of his living room. One hand twitched at the curtains he had moved aside just enough to peek through. The other rested on the butt of the old revolver he had taken down from its box in the back of the closet. A dreamlike expression rode his wrinkled old face as he stood there, caught between wondering if that window could indeed act like a magnifying glass and burn right through him, and the vivid memory of bringing his wife Sally home to that house for the first time.
