It's been a very good time for boxing books in the past few years... From Moyle's works on Miske and Langford to Compton's work on Greb to Pollack's series on Johnson and now Dempsey... Every bit as good as those is this trilogy. Don't sleep on it. So much to learn about how boxing worked during its Golden Age... https://www.amazon.com/Biographies-Memoirs-One-Jack-Hurley-Books/s?rh=n:2,p_lbr_books_series_browse-bin:The+One+is+Jack+Hurley
