I don't know what it is with me, but nearly everything I read, buy or browse, is historical fiction. It may be a historical mystery, but, it is historical fiction nonetheless. My question is why do I enjoy reading historical fiction more than fiction that was written years ago. Case in point...I like reading Arthur Conan Doyle's Sherlock Holmes. One of my favorite authors and certainly one of, if not my favorite, literary characters. However, I don't have a need to read all the stories. But then I read one of the books in Laurie King's Mary Russell series, or one of Nicholas Meyer's books and I can't wait to read the next. The styles are akin to Doyle's. The characters are either about Holmes or his fictitious wife Mary Russell or even Doyle himself. To my amateur understanding, there is no real discernible difference between the "real Holmes" and the historical fiction Holmes. Maybe it's best to read them at the same time.
With that being said, I'm reading Laurie King's A Letter of Mary and Arthur Conan Doyle's A Study in Scarlet. The King book is book 3 in the Mary Russell and Sherlock Holmes series and of course, A Study in Scarlet is the first Doyle story to feature Holmes.
