John’s Wood London, England “David, open up!” Kate pounded on the door of David’s house on Clifton Hill. Her fist thudded dully against the solid oak of the door but Kate carried on, ignoring the pain. David was in there; there were lights showing on the upper floor. He has to be there, she thought desperately, hoping she wasn’t too late. A thumping came from within marking the descent of someone down the stairs and a moment later the door swung open and David stuck his head out in disbelief. “Kate, what are you doing here? I thought you said you didn’t want to go back.” “David, thank God you’re not gone yet!” “Gone, but I’ve…” “No time for talk, David,” she rushed on as she went inside. “I need your help. Lord Harrowby has appendicitis and it’s bad. He needs a doctor, a real doctor to fix it and there isn’t one around here who can save him.”
