PGW was, and probably always will be, unsurpassed as a writer of sparkling comedy. I collect the books on a modest scale, and have done since schooldays in the sixties, and I'm sure I've read 'Pearls, Girls and Monty Bodkin', but can't recall the 'irising' bit. Probably just advancing age.
Talking of which, I was brought up with a start recently when I read somewhere that that amiable old buffer Lord Emsworth of the Blandings stories, although seemingly in his dotage all through the saga, was actually supposed to be slightly younger than I am now. I think, if I recall correctly (and that's by no means certain) that his age was given as around fifty-six in one of the stories. But none of Wodehouse's characters ever aged, so Lord Emsworth was, presumably at that age throughout.
Probably just another of those signs of ageing, like policemen looking younger and modern pop music getting on your nerves.
It's lovely to know that P. G Wodehouse is as popular as ever. His writing never fails to cheer me up.
