Book and movie about Sherlock Holmes's sister prompt a lawsuit

The upcoming Netflix adaptation of a YA novel is causing some controversy … and for once, it’s not disgruntled fans of the book who are to blame.

Nancy Springer’s Enola Holmes follows the teen sister of Arthur Conan Doyle’s beloved detective, Sherlock Holmes.

The Digital Spy explains that Doyle’s final ten Sherlock Holmes stories remain property of his estate, while the rest are in the public domain.

In those stories, Sherlock Holmes begins to show more emotion and becomes "warmer,” and since Holmes does the same in both Springer’s book and the Netflix adaptation of it, the Doyle estate is suing for copyright infringement and trademark violations.

Netflix’s Enola Holmes, starring Millie Bobby Brown of Stranger Things fame, comes out tomorrow — when the Digital Spy expects more movement in the copyright lawsuit.
