A waiter was at his elbow. "Do you feel ill, sir?"

And then, on unsteady feet, he was being led away. Behind him he heard the music once again, heard the rising hum of voices.

Someone set his hat on his head, was holding his coat. The cold air of the night struck his face and the doors sighed closed behind him.

"I'd take it easy going down the step, sir," counseled the doorman.

An aero-taxi driver held open the door of the cab and saluted.

"Where to, sir?"

Wilson stumbled in and stammered out his address. The taxi droned into the traffic lane.

Hands twitching, Wilson fumbled with the key, took minutes to open the door into his apartment. Finally the lock clicked and he pushed open the door. His questing finger found the wall switch. Light flooded the room.

Wilson heaved a sigh of relief. He felt safe here. This place belonged to him. It was his home, his retreat....

A low laugh, hardly more than a chuckle, sounded behind him. He whirled and for a moment, blinking in the light, he saw nothing. Then something stirred by one of the windows, gray and vague, like a sheet of moving fog.
