In the novel Lord Edgware Dies, Jane Wilkinson is an American actress, who has starred alongside Bryan Martin in several films. She is also the estranged wife of Lord Edgware, whom she wants to divorce.
Jane had left the stage on marrying Lord Edgware, but returned to it shortly afterwards. Eighteen months after the marriage, she acted in films in America, and had recently appeared in a successful play in London.
She is very beautiful, and has fair hair, blue eyes, and a husky voice. She is described by those who know her as amoral, and an egoist, seeing only what she wants and nothing else.
She wants to divorce her husband, and marry the Duke of Merton, having fallen in love with him when he did a tour in America.
