A Presumption of Death A Presumption of Death A Presumption of Death is a Lord Peter Wimsey-Harriet Vane mystery novel by Jill Paton Walsh, based loosely on "The Wimsey Papers" by Dorothy L. Sayers. The novel is Walsh's first original Lord Peter Wimsey novel, following "Thrones, Dominations", which Sayers left as an unfinished manuscript, and was completed by Walsh. "A Presumption of Death" is written by Walsh, except for excerpts from "The Wimsey Papers". Harriet, Lady Peter Wimsey, has evacuated her family to the Wimseys' country house, Talboys in Hertfordshire, taking her two children, along with the three children of her sister-in-law, Lady Mary,
Lord Peter Wimsey for their evocation of that period as much as for the intrinsic detective mysteries. It was left to Jill Paton Walsh to extend Wimsey's career through and beyond the Second World War. In the continuations "A Presumption of Death" and "The Attenbury Emeralds" Wimsey and Bunter have returned successfully from their secret mission in 1940 and his nephew Lord St. George is killed while serving as an RAF pilot in the Battle of Britain. Consequently, when Wimsey's brother dies of a heart attack in 1951 during a fire in Bredon Hall at Duke's Denver, Wimsey becomes the Duke of Denver.
