This was such a great puzzle book and I learned a lot about different people and ciphers, puzzles and codes that were used during war.
These puzzles are just challenging enough. You might have to work on one for a day or two but some you can breeze through.
If you like puzzles, i definitely recommend any by Dr. Gareth Moore.

Really, fun, a variety of puzzles and lots of spy facts. I also appreciated that the puzzles didn't necessarily build on each other so you could skip one and come back. I think British people would have an advantage because I didn't know some of the hints.
Also the sudoku type puzzles with letters were the bane of my existence.

Favourite Quote: The fictional British Secret service agent is aided in his daring exploits by gadgets supplied by Q branch, such as the infamous booby trapped attaché case. This incredible device was, in face, a real invention from the Second World War and was primed to explode when the lid was opened. Flemming himself worked in British Naval Intelligence and conceived Operation Goldeneye, a wartime plan to splay on General Franc’s Spain, so it is unsurprising that his wartime experience gave inspiration to his novels.
Favourite Quote: Kings were expected to hide their thinking from all but their closest advisers, partly because household spies were an accepted fact of elite life in the past. Even if it only resulted in gossip and did not cause a political crisis, monarchs required their officials to keep secret any knowledge that touched the wellbeing of the king or the health of the realm.
An engaging read packed with fascinating facts! It was a refreshing change from my usual choices, and I found the facts more enjoyable than solving the puzzles themselves. That said, I was pleasantly surprised at how skilled I was at certain ones. However, some of the puzzle text wasn’t very clear, so took me a while to figure out. A glossary would have been a fantastic addition!

Fun, but has nothing on Murdle. I like the variety of the puzzles in this book, as well as the mixed in history lessons. However, as someone who hates using hints, some of these are literally impossible to solve if you don't just know off the top of your head a random name (of something or someone) from history. They'll just be like "unscramble these letters" then it's "Signor Emblebum McFidleston" with no additional way of getting to that answer other than the scrambled letters. Still fun if you wanna mix it up!
*update* this does get better as it goes along, but still has some of the above issues. Overall a fun puzzle book and would recommend!
