both the book and the film be excellent in their own right . they do differ slightly but that enhances and not detracts from what be an excellent script and act . the historical atmosphere and the young girl look for love and the amazing background of music hall and the voyage into the lesbian world of london early twentieth century make this an exceptional movie . andrew davy a the scriptwriter excel himself a he write this lesbian love story with such sensitivity . rachael sterling and keeley hawes be both excellent actress and give these part their best . the rest of the cast be very good . if there be high than positive i would give it .
