Thrones, Dominations and A Presumption of Death, by Jill Paton Walsh (and Dorothy Sayers)
Though I’m not a Sayers expert, it seems to me Jill Paton Walsh carries off these post-Sayers Wimsey-Vane mysteries admirably. Sayers, it seems, lost interest in Thrones, Dominations after penning a partial manuscript and some notes. In 1986 the publisher approached Walsh with the manuscript, and she agreed to complete it. (Who wouldn’t?) The result is the first full-length work to pick up with Peter and Harriett’s married life in London. It follows Busman’s Honeymoon, set in Harriett’s hometown of Hertfordshire.
During WWII Sayers published some letters by members of the Wimsey family that provided the public with a glimpse of the Wimseys’ wartime life. These letters provided the inspiration as well as the opening chapters of A Presumption of Death. Harriett, her two children, her nephews, and a niece are back in Hertfordshire. Peter is on the continent doing (what else?) top-secret intelligence work. When a murder takes place during a village air raid, Harriett, of course, agrees to help with the investigation.
