The story of Markham Sutherland is presented through various letters, journals, and the third-person account of the novel's supposed editor, Arthur. Sutherland, under pressure from his father to become a clergyman, confesses to Arthur his reservations about accepting the
Thirty-Nine Articles and contemporary English Christianity in general. In particular, Sutherland is concerned about the depiction of God in the
Old Testament, God's patronage of the Israelites on non-moral grounds, the doctrine of
Eternal Punishment, and the supposed
inerrancy of the Bible. Sutherland was profoundly influenced by
John Henry Newman in his early years, but was ultimately unable to accept Newman's doctrines. Sutherland also seeks guidance in the writings of Victorian historian and sage
Thomas Carlyle (who was Froude's chief intellectual influence in later years), but finds no solutions. Tormented by his doubts and subsequent alienation from his family, Sutherland becomes morbidly depressed. On Arthur's advice, Sutherland takes orders, hoping that his doubts will eventually pass when he enters a more active life. Because of the selectivity of his sermons, however, his parishioners begin to suspect him of
Socinianism. When Sutherland is tricked into making a harsh criticism of the
British and Foreign Bible Society, claiming that the text of the Bible without clerical guidance is more likely to lead to wickedness than to Christian faith and virtue, his doubts are revealed, and he is forced to resign his position. Sutherland travels to
Como to rest and recover from illness, indulging in free religious speculation while there. He befriends Helen Leonard, who sympathises with his troubles and listens to his doubts. Helen's dull, unloving husband prefers to spend time away from his wife, and leaves her in Sutherland's company for the season. Helen and Sutherland fall in love, causing both great anxiety, although the relationship never becomes physical. The two consider eloping, but Helen decides she cannot leave her daughter, Annie. During this conversation, however, the unsupervised Annie dips her arm into the lake, causing her to fall ill and die soon after. Sutherland again becomes depressed, believing that his religious speculations have brought himself and Helen into
sin. He plans suicide, but is stopped at the last moment by an old friend, representative of
John Henry Newman. Sutherland retires to a monastery, although his repentance is short lived, and he dies still in doubt. Helen, meanwhile, separates from her husband and retires to a convent, although she is unreconciled with the Church because she maintains that her love for Sutherland is holier than her marriage. ==Major themes==
