Nell got into the elevator, punched the button for the lobby, and held 
down the DOOR CLOSE button. The girl thought for a moment, then stepped forward 
to hold the door. Several more girls were running down the hall. Nell kicked 
the girl in the face, and she spun away in a helix of blood. The elevator door 
began to close. Just as the two doors were meeting in the center, through the 
narrowing slit she saw one of the other girls diving toward the wall button. 
The doors closed. There was a brief pause, and then they slid open again.
