It does not take a master detective to deduce that Millie Bobby Brown is about to be a huge star. According to Deadline, the Stranger Things favorite has just signed a deal with Legendary Entertainment to both star in and produce a film series based on the Enola Holmes Mysteries by Nancy Springer. The first book in a collection of six is called The Case of the Missing Marquess, and it kicks off the adventures of Sherlock Holmes’s much-younger sister, Enola, who neither he nor his brother Mycroft take very seriously, and they try to ship her off to boarding school after their mother disappears. Enola of course won’t have that, so she runs away and ends up encountering various mysteries and kidnappings to solve. More familiar figures, like Dr. John Watson, show up throughout the series to bring Enola along on her journey to becoming the next top mind in the Holmes family. Brown signed the deal with Legendary after working with the studio on the forthcoming installment in the Godzilla franchise.
