Why? That’s mainly because death was the fate of Mary Watson in the original Sherlock Holmes series of stories. “While we play fast and loose with the original stories, we generally follow the trajectory of what Conan Doyle did,” “Sherlock” star Martin Freeman tells the Telegraph in a recent interview. “[Watson] gets married, and then Mary dies — so at some point presumably she’ll die.”
Don’t worry about losing Amanda Abbington — the actress who plays Mary on the show as well as Freeman’s real-life partner. Freeman also points out that Abbington will be around the program “for the foreseeable future.”
Fans will just have to hope that she will survive at least until Season 5 of the always-delayed British series.
