Grace had heard a car pull up the gravel driveway, but couldn't tell if it was Jim's car or  if it belonged to someone else. She did not have an ear for car engines like her husband did. Deciding to get up and check, she entered the house through the glass doors and walked through the rooms til she arrived in the living room, calling out, "The door is open! Come on in!" In the background, you could still hear the radio going, but now it was a Jim Croce tune.
