In 1966 there was an episode of Dr Who with William Hartnell. This featured a puzzle which I persuaded my father to make for me, and since then I have amassed a wide range of puzzles. A few years ago my wife, who was president of our local W.i. at the time, suggested I give a talk about them. If you are looking for something a little different then you have come to the right place!

** Update **. The selection of puzzles has been updated, with new ones added this year!
