This engaging mystery was co-authored by Dorothy Sayers and Robert Eustace, a physician and author who provided pivotal scientific information and plot ideas . It is written primarily in epistolary form. It features the character of forensic analyst Sir James Lubbock, who is a character in several of the Lord Peter Wimsey mysteries, although Lord Peter himself is not a character in the story. This is, in fact, the only mystery novel written by Sayers that does not include Lord Peter. (Summary by Ciufi Galeazzi)
