The GCHQ Puzzle January 31, 2016

Sometime in December, I received an email from my friend Delia, who forwarded me a Christmas card in the form of a puzzle from Britain’s spy agency GCHQ (Government Communications Headquarters).  The puzzle consisted of a grid with a series of numbers and one had to deduce the pattern it produced.  It was engaging and I sent it on to two friends of mine from Marin Oratorio, Julie and Mike, who I suspected would enjoy it too. 

It turns out, however, that the grid was just part 1 of a 5-part puzzle and that each subsequent part had multiple subparts.  I was clearly now out of my element, but fortunately Mike was in his!  He proved to be a good match for these geeky “spy guys”, because many of the puzzles involved computer codes and languages, Dr. Who, Lord of the Rings, John Le Carre, and some Harry Potter thrown into the mix – none of which I had read or knew anything about.  Mike and I egged each other on, but he is responsible for 95% of the success.  The deadline was today, and with a bit of cheating along the way (shall we call it reassurance?), we have made it to the end!  Now we need a new puzzle passion – any suggestions?
