Luke's Wife by Evelyn R. Garratt

Rachel was not very sorry to remember that Gwen would be leaving in a / few days. She might do a great deal of mischief if she stayed longer / with them. Anyhow she would probably make Luke unhappy if she talked to / him in the same way as she had spoken to her.

But there was only one part of Gwen's conversation that had effect / on Luke, and that was the fear of Rachel's health suffering from the / change from the country to the overpopulated town.
