Established for more than 70 years on Curzon Street, and considered by some to be the best small bookstore in the English-speaking world (John Le Carré, who set a scene in Tinker Tailor Soldier Spy here, is a long-standing customer), Heywood Hill stocks both new and antiquarian books. Here's where you can pick up a leather-bound volume on architecture, gardening, natural history, and topography—in which the antiquarian collection specializes. The contemporary selection
emphasizes literature, history, biography, travel, architecture, and children's books. During World War I, author Nancy Mitford helped keep the bookstore going. Today, the descendant of her brother-in-law, the Duke of Devonshire, remains the major stockholder.
