A serious and pious young girl, she has become fascinated by a young man of bad reputation, Arthur Huntingdon, a Byronic figure of great fascination but also of hardly-concealed moral failings. She marries him, fatally confident that her love will reform him. For a time all goes well, but gradually he resumes his drinking and womanising, and Helen becomes increasingly unhappy. A son is born, but her husband's debaucheries become more frequent and more organised. When he begins to corrupt his son into his own 'manly' habits she decides to flee, and after an aborted attempt, sadistically thwarted by her husband, she finally achieves her aim, fleeing to Wildfell Hall, in the vicinity of her brother, who is Frederick Lawrence.

When Arthur is on his death-bed, Helen returns to him and watches helplessly as he dies unrepentant. After some delays and misunderstandings she marries Gilbert Markham.

The novel was so unsparing in its depiction of drunkenness and debauchery that Charlotte tried to prevent any reprinting of it after her sister's death. Anne's aim, however, was entirely to warn by depicting vice as it really is, unattractive and soul-destroying. Many modern critics have seen parallels in the novel to Wuthering Heights, signalled by the W.H. house name and plethora of characters whose names begin with H, but more importantly in the similar themes covered: drunkenness, corruption of children, mistreatment of women and so on. They have believed Anne wished her novel to see these things in a proper moral context, something conspicuously lacking in her sister's novel. However that may be, the novel has certainly increased in reputation in our own time. Many find the moralising too insistent, but it is firmly grounded in situation and characters, and the stern tone is mitigated by the discussions of the doctrine of universal redemption.
