Why did everybody have to stand along the side wall?

Not one broad space of the side wall gave results.

Those against the two side walls are not so well cut.

What had been the floor was now a side wall.

One of them had worked his way along the side wall.

She decided to try and get to the side wall.

A little later he was found dead by a side wall.

The man had come through a secret door in the side wall of the office.

He put his hands before him and found the side wall.

The side wall fell behind him and suddenly he was alone.
