Synopsis

Während Sherlock damit beschäftigt ist, herauszufinden, was Moriarty nach seinem Tod plant, verwirrt ein mysteriöser Fall das Scotland Yard. Aber Sherlock ist eher interessiert an einem scheinbar trivialen Detail. Warum zerstört jemand Bildnisse der verstorbenen Premierministerin Margaret Thatcher? Ist es das Werk eines Verrückten, oder ist eine viel dunklere Macht am Werk?
