As one of the three most famous immigrant writers in England, Naipaul creates works with such typical themes as cultural displacement, exile and identity. But in his novel HalfaLifehe chooses to keep away from these.

It may be a positive suggestion for those immigrants who are puzzled by cultural identity.
