In this steamy novel of bondage and abandon, Richard, an Englishman in Hamburg, is introduced by Margaret Wagner to her beautiful niece Helena, and with them experiences the thrills of sexual slavery and transvestism. A shadow falls across Richard's pleasures, however, when he discovers the strength of Margaret's hold over Helena. Thwarted in a misguided attempt to rescue the submissive Helena, Richard soon finds himself in the sensual tutelage of another of Margaret's business acquaintances - one who will teach him in full the true meaning of obedience.
