Harriet Deborah Vane, later Lady Peter Wimsey, is a fictional character in the works of British writer Dorothy L. Sayers (1893–1957).
Vane, a mystery writer, initially meets Lord Peter Wimsey when she is on trial for poisoning her lover (Strong Poison
) – the detective falls in love with her and proposes marriage but she refuses to begin a relationship with him, traumatised as she is by her dead lover's treatment of her and her recent ordeal. In Have His Carcase
she collaborates with Wimsey to solve a murder but still finds him to be overbearing and superficial. She eventually returns his love (Gaudy Night
) and marries him (Busman's Honeymoon
