Grace Livingston Hill 
The White Lady 

When Pastor John Endicott returns from burying his mother, he discovers the legendary ‘haunted’ house in town really is inhabited, and he sets out to determine if the lady in white is a ghost or real. Constance Whetherhill left the city when her wealth failed, and renting the “haunted” house was the most economical choice she could make. But when wealth and privilege are offered back to her, she must choose between the new life with the young dedicated pastor and the old life she was raised to expect.
