I enjoy almost all things Sherlock Holmes. The creme de la creme is the Benedict Cumberbatch version of Sherlock. Alas the next new episode is not scheduled until mid-2016. In the meantime I have been sampling other Sherlock interpretations.
There is the CBS television series Elementary. I like the actors and it is well written. It is not as brilliantly plotted as the PBS version. After 3 seasons I am tiring of it.
Another approach is to introduce new characters. Another PBS production, Arthur and George, focuses on Sir Arthur Canon Doyle, the creator of Sherlock Holmes, as a detective. I watched it on-line and found it very dark. Literally dark, as in hard to see. And unnecessarily convoluted. It did not satisfy.
Another recent discovery is the Mary Russell mystery novel series by Laurie R. King. She has created a character who meets a retired Sherlock Holmes as a 15 year old and becomes his apprentice. Mary has a similarly brilliant mind. There are a great many books in the series and I have only read 3 so far. My mom has read all of them and cannot wait until Ms. King writes another one.
