Magdalen and her sister Norah, beloved daughters of Mr and Mrs Vanstone, find themselves the victims of a catastrophic oversight. Their father has neglected to change his will, and when the girls are suddenly orphaned, their inheritance goes to their uncle. Now penniless, the conventional Norah takes up a position as a governess, but the defiant and tempestuous Magdalen cannot accept the loss of what is rightfully hers and decides to do whatever she can to win it back. With the help of cunning Captain Wragge, she concocts a scheme that involves disguise, deceit and astonishing self-transformation. In this compelling, labyrinthine story Wilkie Collins brilliantly demonstrates the gap between justice and the law, and in the subversive Magdalen he portrays one of the most exhilarating heroines of Victorian fiction.
