One of the first books I was ever given was Sycamore Square. It was old for a toddler, but a pretty thing to grow into: light verse, which had mostly first appeared in Punch. Ernest Shepard’s drawings showed willowy, upper-middle-class young men and women of the sort my parents had aspired to be in their youth. I later discovered that its author, Jan Struther, was the creator of Mrs Miniver, while ‘Sycamore Square’ itself was just off the King’s Road. My grandmother lived around there. It was a rather grand world, brittle and tinkling, and its idea of art was light entertainment.
