The two Mrs Grenvilles - Dominick Dunne

When showgirl Ann Arden meets Billy Grenville, heir to a New York high society's family fortune, it is love at first sight. They get married, but Ann has to face her indomitable and disapproving mother-in-law, Alice. Ann's difficult social ascent is suddenly interrupted the night she shoots and kills her husband, claiming that it has been a terrible accident. Alice has no doubts that her son was murdered, but nevertheless uses all her influence to ensure that Ann is acquitted to save the family reputation, binding the two Mrs Grenvilles in a conspiracy of silence.
