Elena, princess of Wales, the Diana-like heroine of this enjoyable mystery thriller from Froetschel (Interruptions
), yearns for respect, to be free of her claustrophobic marriage and to lead a fulfilling life. Adding to her woes is an antiroyal faction intent on destroying the British monarchy, whose members include the widowed queen, Catherine II; Elena's estranged husband, Edward, prince of Wales; and their sons, 13-year-old Richard and 10-year-old Lawrence. When several of Elena's protectors are murdered, starting with her divorce solicitor, Elena fears she may be next and begins to plot an escape aided by a daring American freelance journalist, Michael McLarrity. Froetschel offers a nuanced view of Elena's relations with the royal family that closely follows the obvious historical model. Readers looking for a less tragic fate for the late Diana, princess of Wales, will find much to like in this beguiling what-if. (Dec.)
