“Galileo had the experience of beholding the heavens as they actually are for perhaps the first time, and wherever he looked he found evidence to support the Copernican system against the Ptolemaic, or at least weaken the authority of the ancients. This shattering experience—of observing the depths of the universe, of being the first mortal to know what the heavens are actually like—made so deep a an impression… that it is only by considering the events of 1609… that one can understand the subsequent direction of his life.”

Afterword to The Dud Avocado (2006)
Context: Halfway through writing the book, I still had no title. It came wonderfully into being when I complimented my host at a party on his flourishing avocado plant. I said, I’d kept trying and failing with my own avocado pits. Someone said, what you’ve got is a dud avocado, and Ken said, that’s a good title for a novel. I thought, this title is mine, and it was. Ken and I had the same agent, and for a publisher we decided on Victor Gollancz, who was so good with first novels. Wonderfully, he accepted it, but with several caveats. He didn’t like the title. It sounded like a cookbook. He also wanted me to write under my married name. I said no to both. He accepted. He decided it needed a subtitle, "La Vie Amoureuse of Sally Jay in Paris." I said, Oh no, no! He said, this was the first time in his experience that an unknown writer had complained about a book cover. However, he did put on the book’s jacket that the subtitle was the publisher’s. Ken read it in proof and said, "You’ve got a thumping great best-seller here." Curiously, the first thing I felt was relief. I believed him. No one could predict how a play or novel would be received by the public like Ken could. And only then was I set free to let excitement take hold of me.
