The beast was across the street and into an empty window in three huge bounds.
He turned without a word and led the way down the hallway towards the empty window.
The office building across the street was a grid-iron of dark and empty windows.
He stood there, boiling, looking into the shadows through the great, wide, empty window.
He opened the door to see an empty window open to the sea.
The empty windows were like mirrors with the night behind them.
I looked at the empty white window, peering too high for the trees.
The empty window looked out on to the apartment block opposite.
I walked the streets in the East 50's, looking for empty windows.
"Now I always walk around with my vision up, looking for empty windows."
