Thanks. I got the answer - the letters anyway - but it never occurred to me there might be an apostrophe in that word. And a strange looking word it is! I'm relieved to know Doc didn't commit a solecism. I have always respected him a lot, even if his puzzles tend to be easier than other setters' efforts. He's been around as long as I've been doing the Spectator puzzles (well, Jac was still a solo act for a few months at the start I seem to recall), and I hope he remains for many years to come.
