Yesterday, I had a go at one of the codeword puzzles that is in the book I wrote about on November 19th.
It took me a while to get into it. I sat there for quite some time trying to work out where the 'E' should go after I had already inserted the head-start letters.
I made a mistake or two along the way, but found my way back before I reached the point of no return.
28:24 was the time it took to complete. That is higher than my target of twenty minutes.
