And on the other side, the Voice had come to life.
After a moment a girl's voice came on the line.
As if in answer to her thought, the voice came again.
For a moment he couldn't work out where the voice had come from.
A moment later the security chief's voice came over the line.
Just when she was ready to give up, a woman's voice came on the line.
The voice came from above them and to their right.
The voice had come from the other side of the door.
The voice came from behind her, and she turned quickly.
A deep and very clear voice came from the other end.
