This paper aims to analyse the way the narrator`s view of modern women`s social work negatively affects the consistency and wholeness of the narrative, in D. H. Lawrence`s The Lost Girl. Many critics have considered The Lost Girl as an unsuccessful novel, generally arguing that it lacks a consistency between the English and the Italian parts of the novel. Basically agreeing with them, this paper focuses on the problem of inconsistency in the characterization of Alvina, the heroine of this novel. It arises from the discrepancy between the Alvina as represented by the narrative itself and the Alvina conducted by the interfering narrator. Unlike Ursula Brangwen in The Rainbow and Women in Love who has a depth of insight and feeling, Alvina should have been let to live an ordinary living as a rather common girl of declining mercantile class. However, as soon as she actually takes a nursing position, the narrator interferes and prematurely dismisses the episode and furthermore, makes a sweeping criticism of the common people and their way of life. The narrator`s criticism of modern mechanical work or modern women`s preoccupation with `social` work is acceptable and valid to some extent. Nevertheless, the narrator`s pertinacious denial and neglection of her commonness or her search for common career makes this novel unconvincing, and unpopular as well.
