This is about Lillie Langtry, a hidden river, the origin of Gray's anatomy, Julian Asange, Jane Austen, PG Wodehouse and Harrods. We end at Knightsbridge station. I shall be waiting in The Genadier from 7.00 pm till 7.30 pm, wearing a bright red shirt. If you are late or lost, phone me on[masked]-2932. From Hyde Park Corner tube station take exit no 3 (Grosvenor Place) then turn right. After 50 yards turn right again along Grosvenor Crescent. When you reach the statue with dogs, turn right again. Soon you see a small very unpromising lane called Wilton Row. Despite your reservations you walk along it. At the very end is The Grenadier.
