By Dr. Joel Norris. Dr. Joel is positioning the book as a preventive of sorts, as you can see on the back cover; the front cover is struggling with some taste issues (the gay-panic textual eyebrow-waggle of italicizing the word "LOVERS!").
This paperback is in decent shape, with slightly aged pages, a creased spine, and a previous owner's name and home info on the flyleaf, so you might be wondering if that price point is a typo. It isn't -- this very early complete account (of info we now take for granted as common knowledge) is quite rare. A good investment for case completists, and those who like contemporaneous accounts of major cases.
