The clock had just struck 11 when I first became aware of a noise coming from the lift. I opened
the door of our flat and listened: Someone was beating against the door of-the lift and calling out at
the same time.
"What's wrong?" I shouted. "The door is stuck. I can't get out." The answer came back. The voice,
which sounded like that of a girl, came from several floors below.
My wife had now joined me and she went off directly in search of the night porter. After calling to
the girl that help was on its way, I went back into the flat to get some tools. Then I hurried down the
stairs until I reached the place where the lift was stuck.
I tried my hard at forcing open the lift door, taking all the while to the girl trapped inside, but-my
tools were no use for this purpose. Very soon, however, my wife returned. Unable to find the porter,
she had called the police; who promised to send an engineer. For good measure she had also contacted
the fire service.
First the engineer turned up, accompanied by two policemen. Almost immediately afterwards the
firemen arrived, too. With his special equipment it took the engineer only a short while to get the door
open. In spite of her experience, the girl was in good spirits. "I'm hungry." was her only complaint as
she stepped out of her cage.
