A long moment later I heard the front door open.
She led me to the front door and we went outside.
A moment later she heard the front door open and close.
They went to the front door, looked up and down the street.
After what must have been half an hour, she heard the front door open.
More than likely he came in through the front door.
He put his key in the front door and went inside.
Then he saw a black man going in the front door.
He came in the front door and called her name.
We won't use the front door in case they hear us.
