I noted that the puzzle was set by the four time Times Crossword champion
and initially I could see why he was!
I think there is an alternative spelling to one solution which may cause a problem.
That's great: many thanks. I confess that last week I was too embarrassed to add to the list of e-mail requests and popped next door to buy a copy of the magazine -- and found more there that I enjoyed reading than I had expected.
Many thanks for the link, DJA; a little late to the fray this week but it was a useful time passer on a northerly M1 journey! Would agree with Kayakamina on the tricky dual spelling choice.
