Perhaps some of the best moments in a book-lover’s life are when you chance upon something that turns out to be a real find. The first of many such discoveries for me was a well-used Penguin entitled Twenty Years A-Growing, which I came across nearly sixty years ago, in the back room of a junk shop. I bought it for a penny, read the whole book that day and loved every word of it. I have it still and often revisit it.
