Sherlock waits to see where Moriarty will make his posthumous move. One mysterious case in particular baffles Scotland Yard but Sherlock is more interested in a seemingly trivial detail. Why is someone destroying busts of the late Prime Minister Margaret Thatcher? Is there a madman on the loose, or is there a much darker purpose at work, something with its roots deep in Mary Watson's past?

Did You Know?


When Mary is in Norway, two boats can be seen with the names "Flekkete Bånd" and "Løvens Manke". These names both reference, and are direct translations of "the speckled band" and "the lion's mane", two well known tales of Sherlock Holmes. See more »


As a doctor John Watson would have immediately placed Mary flat on the ground and placed pressure on the wound. He would not have just left her propped at an awkward angle and done nothing as she bled out. See more »


[first lines]
Mycroft Holmes: What you're about to see is classified beyond top secret. Is that quite clear? Don't minute any of this. Once beyond these walls, you must never speak of it. A D-notice has been slapped on the entire incident. Only those within this room, code-names Antarctica, Langdale, Porlock and Love, will ever know the whole truth. As far as everyone else is concerned, going to the Prime Minister and way beyond, Charles Augustus...

Series 4 a disappointment
2 January 2017 | by loa-3See all my reviews

We saw the first episode on STAN in Sydney on 2 January. We are absolute dedicated Sherlock fans, but were disappointed with the offering. Not because of what happened in the end- that was predictable. It just seemed as though we were watching a pilot that had not been tightened up either that or the authors had grown tired of the writing the series. It was all a bit sloppy with silly and unnecessary dialog that could have been deleted. And it just seemed as though the whole cast was wondering where it was all going. What was the reason for that ridiculous coiffured Dr Watson hairdo? Freeman just didn't seem the same to us. Was this because of his real life breakup with his partner?

But the biggest omission to my mind: where was that thumping Arnold and Price music that kept the pace of previous episodes. All the dynamic music had been 'sucked out' of the presentation and we were left with limpid weedy muzak that reminded me of cheap 80's drama background of distant wailing strings not all that relevant to the story. It sounded like someone had left the radio on in the background. It was pathetic. It left the characters 'naked' with embarrassing dialog in many of the scenes. So were all of these changes because of budget limitations? Sorry I give it a bare 6.5 to 7/10.
