chunk: Many of the events of the novel are narrated twice; first by the 'editor', who gives his account of the facts as he understands them to be, and then in the words of the 'sinner' himself.
  The 'Editor's Narrative' starts in 1687 with the marriage of Rabina Orde to the much older George Colwan, Laird of Dalcastle. Rabina despises her new husband because he falls short of her extreme religious beliefs, his love of dancing and penchant for drinking alcohol. She initially flees him but her father forces her back, and they live separately in the one house. Rabina gives birth to two sons. The first, George, is indisputably the son of the Laird, but it is strongly implied – though never confirmed – that her second son, Robert, was fathered by the Reverend Wringhim, Rabina’s spiritual adviser and close confidante.
