Anyone solved any of the puzzles yet?
I've done two, so far. Although I'm not convinced about the second one, because it's not a place name. I think I'm well on the way to solving a third one.
Edit: Sorted the second one.
Edit: Third one done, but not totally sure yet. Yes, sorted for definite.
Edit: Fourth one sorted.
Edit: Fifth one sorted.

Spoiler Alert:

Buckingham Palace

Blackpool Tower

University of Cambridge

Edinburgh Castle

Giants Causeway

Stonehenge

I suspect the sixth one is based around the Greek numerals. I thought about Roman numerals, but that is difficult to fit.
So in Greek numerals, assuming the 10 to 30 is out by 20, (but it could be out by 19) that would make the first letter K (or for 19: IT). Then the next, if it was out by 2, it wouldn't make much sense because the second letter would then be B. Whereas if it was out by 12, that would make the second character group as IB.(or for 20 - K)
So we'd have KIB so far (or ITK).
 
Did it yesterday. Managed a few in my head but had to grab a pen and paper for the last few. The final cover picture solved ok (and the hidden bonus message)
Gone Skiing, I think you are over complicating 6

Yep, sorted it. You are right I was over complicating it.
Edited the Spoiler Alert.

Yes, I tried Reading as the first word and it was nonsense.

Done the morse code, that was simple enough.

I can make out the four letter groups, but it's gibberish.

EDIN ECTI PROT GDOM UNIT EKIN NGTH =28 letters
PROT ECTI NGTH EUNI TEDK INGD OM = 26 letters


Having wrote it out, I can see it, but it's still gibberish because there are two too many letters in the code.
It's like one of those exam questions with mistakes in it.

It doesn't have mistakes in it, you have not found the correct answer.

UNITED IN PROTECTING THE KINGDOM = 28 letters, not gibberish
