Then, shortly after she first met consultant neurosurgeon Mr. Adam Ross-Pitt, Henrietta fell seriously ill - and her world changed irrevocably. She had Mr. Ross-Pitt to thank for her new job at the manor-house near his home, but she was sensible enough to realise that he was beyond her reach. If her gratitude tipped into love, there was no need for him to know - even if he did continue to come to her rescue ...
