Gillian Honorine Mary Herbert, Baroness Hemingford,, known professionally as Jill Paton Walsh, was an English novelist and children's writer. She may be known best for her Booker Prize-nominated novel Knowledge of Angels and for the Peter Wimsey–Harriet Vane mysteries that continued the work of Dorothy L. Sayers.

Lord Peter Death Bredon Wimsey is the fictional protagonist in a series of detective novels and short stories by Dorothy L. Sayers. A dilettante who solves mysteries for his own amusement, Wimsey is an archetype for the British gentleman detective. He is often assisted by his valet and former batman, Mervyn Bunter; by his good friend and later brother-in-law, police detective Charles Parker; and, in a few books, by Harriet Vane, who becomes his wife.
