Walter peered into the night. He saw no signs of the movement. The only sounds came from traffic on the surrounding streets. After waiting several seconds to be certain that was all he heard, he took a deep breath and then started down the twin steps. A moment later, he froze.
There it is again.
He looked upward to find that silhouetted leaves of the tree above were almost completely still.
Okay . . . so it’s not the wind.
Once again, the faint sound had been so brief that he had no idea where it might have come from. Turning slowly, he surveyed the street again, paying particular attention to the windows and dark alcoves of the doorways. He saw nothing unusual and bowed his head wearily.
I’m too tired for this . . .
Swinging his head slowly in an attempt to shake away some of his fatigue, Walter stepped back onto the sidewalk. He paused, looked both ways down the street again, and then moved off in the direction that headed toward home. It would take him past one of the two warehouses.
The least I can do is check it out as I go by.
With that silent promise, Walter began walking down the street.
When he reached the first of the warehouse windows, he slowed his pace and tried to glance inside. The windows were dark and so heavily layered with grime that he had no desire to try to rub some of it away. He continued on past the second and third windows with similar results, with the exception that someone had, not very recently, traced a vulgar suggestion involving someone named “Tracy” into the thick dust.
The fourth window provided as little insight into the warehouse’s interior as had the previous ones. For a moment, Walter thought he saw the faint flicker of light inside, and then realized that it was a reflection of the light from across the street. He passed the fifth window almost without a glance, but then stopped when he thought he saw light from within the warehouse again.
It was not a reflection again, as he first thought. Instead, it came from the movement of the glass. It appeared to be vibrating slightly, just enough to make the panes seem to shimmer. Walter placed his fingertips, and then his palm against one of the panes. He could tell nothing for certain, though, through the thick material of his gloves.
He stepped back and studied the other windows again. As far as he could tell in the dark evening, none of the other windows were vibrating in the same way. Whatever was causing movement of the glass within this particular windows seemed to be localized to the end of the building.
Walter looked around for an entrance, but saw none. There were two additional windows ahead of him on this side of the warehouse, before the building ended at a narrow alleyway. Beyond that was an upholstery store that also advertised used furniture. Probably stuff people never paid for or picked up, Walter guessed, before turning his attention back to the mystery of the vibrating window.
