After the death of her family, Mary Russell, a fifteen year-old, moves to a farm with her "evil" aunt. In one of her walks around the area she meets the famous Sherlock Holmes, who is retired and dedicates his hours to the study of bees. Right from the start the two main characters in the book match their wits and Holmes is surprised by the potential he sees in this young woman. He then decides to tutor her and introduce her to the art of investigative work. In the next few years, they go through a few cases and Mary goes away to Oxford to continue her studies; but at one point they are faced with a more dangerous opponent, who wants to kill not only Holmes, but also Mary; even Dr. Watson and Mycroft are in danger. If you want to know the rest, you better read the book!
In my opinion the author does a very good job in maintaining the particular characteristics that define the characters in Arthur Conan Doyle's books, especially in the case of Sherlock Holmes. It is amazing how you feel that the deductive work is done by exactly the same detective you knew from the past, and with the added benefit of a fresh mind assisting him!
I was very pleased to see the ingenious way in which Laurie King connected this new series with the Conan Doyle's work. She concocted a story about her receiving the manuscripts of the different stories in the series some time ago, and that she is merely the editor. The manuscripts were of course written by the enchanting Mary Russell.
Finally, let me tell you that, since I am an avid chess player, I thoroughly enjoyed the way in which Holmes uses a chess game with Mary to explain the strategy he was planning to utilize in one of their cases.
I will definitely continue reading the books in this series, and if you haven't started yet, I recommend you do it now!
