 The village dance and air raid practice, which are the starting point for the plot of "A Presumption of Death", are also derived from one of Sayers' fictional letters, though the idea of making this the scene of a murder to be investigated was Walsh's.Other than the selection made by Walsh and incorporated in her book, "The Wimsey Papers" have never been republished.In the Author's Note appended to "A Presumption of Death", Walsh cautioned the eager Wimsey fans that "The Wimsey Papers are not fiction, and were not intended to be read in a continuous chunk" and that "Some of them are about details of war-time history that would now require extensive footnotes in explication".
