By William R. Drennan. Drennan was a professor of English at the University of Wisconsin and Appalachian State; Frank Lloyd Wright was, well, Frank Lloyd Wright, but you may not know he suffered "the brutal murders in 1914 of seven adults and children dear to" him, and the "destruction by fire of his landmark residence, Taliesin." The cover describes this as "a gripping mystery story"; the cover is also rather lurid, and the writing, while aiming at an academic tone, matches the content.
Still, this is a lesser-known crime of the previous century (not to mention further proof that Wisconsin is kiiiiind of a legendary-case magnet), and at under 170 pages of book proper, you'll likely speed right through it. Said pages are clean and intact; the jacket has some mild shelfwear and a sticker ghost or two, but it’s a good reading copy.
