I recently caught sight of AN Wilson in the London Library.
Wilson had kindly helped me with some research into the novelist Elizabeth Jenkins - so I introduced myself. Alas, this was during the heatwave: I was dressed as if I was on a coach tour.
Wilson, by contrast, resplendent in a double-breasted suit, purple flowery tie and buckled patent leather shoes, could have rivalled a magnificent bird of paradise. Gentleman that he is, Wilson made no sign of noticing this contrast and slipped politely off.
