The tale unfolds effortlessly, bolstered with a set of vivid supporting characters: the ascetic Lady Mary, second wife of the Earl, whose interference partly precipitates the horrific outcome; Father Marty, the priest who equally misguidedly counsels the O'Haras; the beautiful Sophia Mellerby described by Trollope as having 'the intellect ...sufficient to enable her to make use of it'; and Kate's shadowy father, a fugitive convict.
