- Colin MacInnes, Absolute Beginners (1959)
It isn't directly mentioned anywhere, but those in the know will recognise a description of the Churchill Gardens estate in Pimlico, where my dad grew up. The playground was still there in the 1980s (maybe it's still there?) and dad used to take me and my sister to it when we were down there on visits to our granny. Anyway, this is probably the estate's only literary appearance.
