Calibax, you are quite right, when I turned off the computer last night, i went back to the atlas with a magnifying glass, gave up after an hour, then sat with a pice of paper thinking up things 'he' could do, then looking them up in the index of the atlas, such as Bookchurch, Buyring, etc
When I looked up Pickering, I found it just above Malton on the map, so it must be a misprint in the quiz sheet that I have, annoying, but solved now. X
