Lucy uses golf practice as a way to search the grounds. She discovers fur from a woman's fur coat caught on a bush. Then she finds a cheap compact. Lucy takes these to Miss Marple, who believes the murderer knew all about Rutherford Hall. He removed the body from the embankment where it had fallen away from the railway, drove a car outside the grounds at night and hid the body. Lucy finds the woman's body hidden in a sarcophagus in the old stables containing Luther's collection of dubious antiques. Who was she?
