Marnie

Blurb

Marnie is an English novel first published in 1961 which was written by Winston Graham. It is about a young woman who makes a living by embezzling from her employers, moving on, and changing her identity. She is finally caught in the act by one of her employers, a young widower named Mark Rutland, who blackmails her into marriage. Two shocking events near the end of the story send the troubled woman to the brink of suicide and she eventually must face the trauma from her past which is the root cause of her behavior.
It was the basis for Alfred Hitchcock's suspense film Marnie, where the setting was changed from England to the United States, details of the story were changed, and the ending was changed to a more optimistic one. It was also adapted into a play by Sean O'Connor in 2001.

His younger child's babysitter was a good looking girl who was constantly taking showers and getting letters from her mother about dangers of getting involved with men, and she had a strong interest in riding horses;
