For our final (!) post about H.H. Holmes in this twenty-four part series (!), we return to Frank Geyer. Remember our tenacious Philadelphia detective who was integral to the conviction of Holmes? Geyer went on to pen a book about the case after Holmes was executed. As it was a first-hand account of the investigation, the book was quite the rage at the time.
The book has passed out of copyright, so you can purchase a relatively cheap reprint of it online. Detective Geyer nor his estate will make any money off the sale, but I like to help keep his name alive on Amazon. Ha.
