I think this would really appeal to Conan Doyle fans overall. It was fairly interesting as it covered not only Conan Doyle, his activism, & his writing of Sherlock Holmes, but the general state of investigative police work in the early 1900s. (Sadly, there still seem to be some parallels to today where "the other" -- whether race or religion or some other demarcation -- gets railroaded or charged even when innocent.) If you're more interested in the story related to the particular murder itself, the last part of the book is the most interesting. Realistically, I think the part about the murder itself could have made a good, in-depth article in something like the Smithsonian or The New Yorker magazines; it didn't necessarily need to be a book. But, for fans of Conan Doyle or those who want to know more about the general time period, this book gives some additional insight & background.
