He leaves the shop and goes to see his friend the doctor. They have dinner together and the conversation turns to Catherine Weir. The doctor feels that to help her they must know more about her history.
The doctor tells a story to illustrate this point. The story is about Mrs. Oldcastle and her daughter Dorothy, and how the doctor couldn't help Dorothy until he knew her history. She was really ill but what made it worse was the way Mrs. Oldcastle and her maid Sarah tried to control Dorothy. They did not approve of her husband, and would not let him into the house.
Ethelwyn let him in by a secret door, and husband and wife were reunited, but it was too late for Dorothy. She died moments later. Dorothy and her husband were the parents of Judy, Mrs. Oldcastle's spunky grand-daughter.
Mr. Walton decides to preach his next sermon on the gift of the Holy Spirit. He believes that if Catherine Weir will ask for the Holy Spirit, she will receive in him the helper she needs to forgive her father.
In the audience that Sunday, there sit Catherine Weir, Mrs. Oldcastle and Judy, listening to the message about the Holy Spirit: "If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him?"
