Margaret Lockwood devours the screen as a tightly wound seventeenth-century beauty with loose morals, who steals her best friend’s wealthy fiancé on the eve of their wedding. And that’s only the beginning of this piece of pulp from director Leslie Arliss—there are no depths to which this sinful woman won’t sink. James Mason costars, and nearly steals the movie, as a highwayman with whom our antiheroine becomes entangled. This nasty, subversive treat was the most commercially successful of all the Gainsborough melodramas.
