The House of Green Turf — Ellis Peters

MAGGIE
--rich, beautiful, and young. She was a famous opera singer with many admirers, but no long had ever touched her heart. After a near-fatal car crash, a voice from the past haunted her; somewhere at some time, she had wronged someone -- destroyed him -- but the memory kept eluding her. She needed someone to help her find this demon sent to torment her from the recesses of her mind.

FRANCIS
--Handsome and aloof, he was a discreet detective -- had brushed with love, been hurt, and now never let his emotions get out of hand -- that is, not until her met Maggie. His search for the identity of her faceless accuser was more to him than just a case. It became his life.

They were bound together in their search for the truth -- and separated by a wall of fear!
