'Long before I heard of Freud I was interested in reading accounts of first memories and impressions. My own experience had taught me that the roots of life were there but it was never certain, and that was the adventure, how they would emerge. It was partly because of this belief and partly because of a poem with that title by Robert Browning that I called my first book Development. The two volumes I now discovered were linked to this interest and not only gave me great pleasure but won me lasting friendships. They were A London Child of the Seventies (and its sequels) by Molly V. Hughes and Within the City Wall by Margaret Phillips.'
