From the book
Title: Bride of Moat House by Norah Lofts Description: It began when he met Antonia. Richard Curwen fell in love—wildly, passionately—and the lovely Antonia returned his love. But Richard and Antonia were penniless. And too spoiled and selfish to live as ordinary mortals. They wanted the best. The very best. And so Richard married Eloise, Antonia’s frail but wealthy cousin. The resemblance between Eloise and Antonia was astonishing. In fact, most people couldn’t tell them apart. Which was exactly what Richard was counting on.
