'' `` I pray God it will be as you say . '' Several minutes later Walter was on his way to the practitioner 's . In due time he was back and told his father she had promised to come that evening at 7:30 . Promptly at 7:30 the door-bell rang , and Walter went to the door to welcome the practitioner ; he showed her into the parlor and called his father . After a formal introduction , the Rev.
