On 1 January, the first episode of the new series of Sherlock aired — a retelling of the Arthur Conan Doyle story A Scandal in Bohemia called A Scandal in Belgravia. Among several changes from the source material were a few which provoked comment; particularly the decision to adapt the character of Irene Adler (“the woman”, as Holmes calls her).
Instead of an opera singer, she was now a dominatrix. And — spoiler alert — instead of outwitting Sherlock, she was undone by her decision to make a crucial password dependent on her fearsome crush on the great-coated detective.
