Although Helene wrote to the Marks & Co. bookstore for twenty years, starting in 1949, she didn't actually get to travel to London until 1971, when she did things up right and stayed there for a month, getting to know a wide variety of people and being (as far as I can tell) incandescently happy.

Milton assumed I'd read the Christian version of Isaiah and the New Testament and had learned all about Lucifer and the War in Heaven, and since I'd been reared in Judaism I hadn't. So I said, 'Wait here,' and borrowed a Christian Bible..."
