Lord Ronald gave Lady Clare a lily-white doe as a love-token, and the cousins were to be married on the following day. Lady Clare opened her heart to Alice the nurse, and was then informed that she was not Lady Clare at all, but the nurses child, and that Lord Ronald was rightful heir to the estate. Lady Clare dressed herself as a peasant, and went to reveal the mystery to her lord. Ronald replied, If you are not the heiress born, we will be married to-morrow, and you shall still be Lady Clare. (Tennyson.)
